question 25 of 25
scientists compare two different plant species. in species a, the leaf color is
controlled by two alleles. in species b, leaf color is controlled by five alleles.
how will these two plants be different?
a. species b will have a wider range of leaf colors.
b. species b will have more offspring.
c. species a will have a wider range of phenotypes.
d. species a will have a wider range of genotypes

Explanation:

Alleles are different forms of a gene. More alleles (species B has five, species A has two) for a trait (leaf - color here) generally lead to more variation in that trait. Since leaf color is controlled by alleles, species B with more alleles for leaf - color will have a wider range of leaf colors. Offspring number (option B) is not related to the number of alleles for leaf - color. Species A having fewer alleles (two) for leaf - color will not have a wider range of phenotypes (related to the trait's expression, here leaf - color) or genotypes (related to gene combinations) compared to species B which has more alleles.

Answer:

A. Species B will have a wider range of leaf colors.
