A plant that is heterozygous for both traits is crossed with a plant that is homozygous recessive for both traits. What is the genotype and phenotype of the offspring? Saguaro cacti are very tall cylindrical plants that usually have two L-shaped arms, one on each side. Suppose you live in southern Arizona where the Saguaro cactus is common, and you happen to have one growing in your yard. Your Saguaro has two arms, but one is longer than the other. Now, assume that arm length in these cacti i controlled by a single gene with arms of the same length (A) being dominant to arms of different lengths (a). What is the genotype of your cactus? Could one of the parents of your cactus have had a phenotype with arms actusWhen artificial selection is practiced over many generations, it iscommon for the trait to reach a plateau in which further selectionhas little effect on the outcome of the trait. This phenomenon isillustrated as shown. Explain why it occurs.
