A disputed paternity case! Hermione’s new baby has a blood type of O. Her blood type is B and Ron Weasley is A. Harry Potter (blood type AB) insists he is the child’s father. CAN THIS BE TRUE???!
Answer:
No becuase one of the parents needs to have type O
Explanation:
No, this cant be true because in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]".
What type of alleles are blood types?An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele.
Codominant alleles in humans are responsible for determining blood types. There are three distinct alleles, and they are denoted by the letters IA, IB, and i. The IA and IB alleles both have co-dominant inheritance, but the i allele has a recessive inheritance pattern. Type A, type B, type AB, and type O are the four different human phenotypes that are possible for the blood group.
Therefore, in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]"

2. The small molecules move into the?
Facilitated diffusion, like passive diffusion, involves the movement of molecules in the direction determined by their relative concentrations inside and outside of the cell. ... They then undergo conformational changes that allow the molecule to pass through the membrane and be released on the other side.
Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion (or simple diffusion), osmosis, and facilitated diffusion

how do amphibians breathe on land and in water
Answer:
Most amphibians can breathe both through cutaneous respiration (through their skin) and buccal pumping - though some also retain gills as adults. Some aquatic salamanders (and all tadpoles) have gills and can breathe underwater thanks to them. The Mexican axolotl, for example, never loses its gills.

Assume for the purposes of this problem that the order of and distances between three linked genes are the following: unc-32 10mu vab-7 20mu dpy-17 What is the probability of obtaining a phenotypic unc-32 vab-7 offspring from a cross between a heterozygous fly(unc-32 vab-7 dpy-17/ ) and the triple recessive nematode
From the distances between genes and their order, it is possible to get recombination frequencies per region (simple and double recombination frequencies). The probability of obtaining a unc-32 vab-7 + offspring is 0.09 = 9%.
---------------------
We are usually asked to get the order of genes in a chromosome. To do so, we need to get the distances between genes. And to get distances between genes, we need to get their recombination frequency.
When three genes are involved, we get the distances by taking the recombination frequency, P, per region.
We talk about regions, R, when we are making reference to the space between two genes.
Gene 1 -----(R1)----- Gene 2 --------(R2)------ Gene 3
P1 P2
P1 = recombination frequency between Gene 1 and Gene 2P2 = recombination frequency between Gene 2 and Gene 3⇒ P1 = (SR + DR) / N
⇒ P2 = (SR + DR)/ N
Where:
SR is the number of simple recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals.The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU).
In the exposed problem, we need to do the inverse way. We already have the order and distances between genes, and we need to get the recombination frequency, P.
We know that the order of genes is as follows,
unc-32 ------------- vab-7----------------- dpy-17
Distances are:
Region 1 = 10 MURegion 2 = 20 MUWe need to get the probability of obtaining a phenotypic unc-32 vab-7 + offspring from a cross between a heter0zyg0us fly (unc-32 vab-7 dpy-17/ + + + ) and the triple recessive nematode (unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17).
Cross:
unc-32 vab-7 dpy-17 / + + + x unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17
To get the genotype unc-32 vab-7 + , a simple recombination, SR, must occur in region 2.
So we need to get the simple recombination frequency in Region 2.
To do so, first we need to clear the following equation
Distance between vab-7 dpy-17 = P2 x 100 = 20 MU
20MU = P2 x 100
P2 = 20 / 100
P2 = 0.2
The recombination frequency in region 2 (P2) is 0.2.
Now, we need to get the simple recombination frequency in this region.
P2 = (SR + DR) / N
P2 = Simple recombinants Frequency + Double recombinants Frequency
R1 = 10 MUR2 = 20 MUDouble recombinants Frequency = 10% x 20% = 0.1 x 0.2 = 0.02P2 = Simple recombinants Frequency + Double recombinants Frequency
0.2 = Simple recombinants Frequency + 0.02
Clearing the equation,
Simple recombinants Frequency = 0.2 - 0.02 = 0.18
Simple recombinant frequency in region 2 will produce the following two chromosomes,
unc-32 vab-7 ++ + dpy-17So half of this frequency will produce one chromosome, and the other half will produce the other chromosome.
unc-32 vab-7 + ⇒ 0.09+ + dpy-17 ⇒ 0.09So, the probability of obtaining a phenotypic unc-32 vab-7 + offspring is 0.09 = 9%.

Examine the comparison between a eukaryotic cell and a prokaryotic cell. Which two lettered choices provide a comparison of structures that encode genetic information for the cells? A) A and D B) B and D C) C and D D) None of these choices, as prokaryotic cells do not contain DNA
I am almost certain it is A) a and d) but I need reassurance.
Answer: c & d
Explanation:
C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.
What are Prokaryotic and Eukaryotic cells?Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.
Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.
Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

IF a man with blood type A, one one of whose parents had blood type O, marries a woman with blood type AB, what are the putative genotypes of the offspring?
Answer:
The 1st child will surely have AA,The 2nd might have AB/OB and the last one will surely have OB
Explanation:
I studied at school like 2 yrs ago
I am sure
Answer:
If the man has blood type A one of whose parents had blood type O then he must be having the genotype IAi and the woman with blood group AB would have genotype IAIB. So if they produce offspring than the putative genotype of the offspring would be IAIA, IAi, IAIB, and IBi.
Explanation:
IA i
IA IAIA IAi
IB IAIB IBi
Therefore out of four offspring, two offspring would be having A blood group, one offspring would have AB blood group and one offspring would have B blood group.

Fill in the blank with the correct term to complete the sentence provided. When the valve between the right atrium and right ventricle has an abnormal narrowing, this is known as
(Answer is NOT pulmonary valve or pulmonary stenosis)
Explanation:
if its correct please let me know
A narrowing of the valve between the lung arteries and the lower right heart chamber (right ventricle) is known as pulmonary valve stenosis (pulmonary arteries).
What is an abnormal narrowing in the heart?The valve flaps (cusps) of a constricted heart valve may thicken or stiffen, as a result, the valve's blood flow is decreased.
When that valve narrows, blood cannot flow correctly and aortic stenosis develops, mild to severe cases of the illness are possible.
The left ventricle of your heart has to work harder over time to force blood past the stenotic aortic valve.
Therefore, an abnormal narrowing of the right atrium and right ventricle is due to pulmonary valve stenosis.
