Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if one dog is true-breeding for the long-coat trait and the other dog is true-breeding for the short-coat trait. ResetHelp

100% long-coat

Explanation:

Assuming that the long-coat trait is represented by L allele and the short-coat trait by l allele.

True-breeding long-coat dog would have the genotype LL while true-breeding short-coat would have the genotype ll.

Assuming that the long-coat trait is dominant over the short-coat trait.

           LL    x    ll

        Ll   Ll   Ll   Ll

All the offspring would have Ll genotype and would appear with long-coat phenotypically. Hence, the proportion of offspring phenotypes is 100% long coat.

answer: c

explanation:

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
