a) In turtles, brown shells and the red legs are most prevalent forms of the traits. Occasionally, green shells and yellow legs are examined. A test cross of a di-hybrid turtle showing both the wild type phenotypes along with a homozygous recessive turtle is carried out. Suppose both the dominant alleles are present on one inherited chromosome and both the recessive alleles are present on other inherited chromosome in the case of the wild type organism.
Complete a punnett square to display the support of prediction which we would expect a 1:1:0:0 ratio of the possible phenotypes in the offspring generation.
