How are traits inherited by offsring?
Answer:
Traits are passed to offspring by the offspring parents.
Explanation:
the genes that control a trait come in pairs, one from each parent. If a gene pair contains a dominant allele (a variation of genes that will produce phenotype,) than the offspring gains that trait from the dominant parent.
Analyze the Punnett square below and determine the the genotypic ratio. Axial flowers are dominant
Answer:
first answer choice
