In a dihybrid test cross a dihybrid is crossed to a test cross parent. The test cross parent is Select one: A. homozygous for the dominant allele for each gene. B. heterozygous for the dominant and recessive alleles for each gene. C. None of the above. D. heterozygous for the dominant and recessive allele for one gene and homozygous for the recessive allele of the other gene
Homework Answers
1) The test cross is a type of backcross in which the parent is crossed with a recessive parent to test the homozygosity of the parent. As in this case it is a dihybrid test cross so parent with which it tested is a double recessive plant for both the traits. So the answer is c. None of the above

Which of the following is true regarding dihybrid crosses? A. Each parent involved in the cross is heterozygous for at least one of the two genes being assessed. B. Two gene loci are assessed and the parents can be any genotype at these two loci. C. There are 9 different fertilization possibilities. D. The ratio 9:3:3:1 means that of the possible outcomes in offspring; 9/16 will express the dominant phenotype for both loci, 3/16 will express the dominant phenotype for...

How do you fill in the boxes?
7.1: Dihybrid Cross in Drosophila melanogaster In this exercise we will be focusing on two genes, one of which controls wing development (ap - apterous and the other controlling body coloration (eb - ebony). Each of these genes has two alleles, where the dominant allele of each produces the wild-type phenotype for their respective trait. When expressed in the homozygous recessive genotype, the recessive allele (ap) for the apterous gene results in a...

A dihybrid cross is performed in Drosophila - one parent is heterozygous for both genes (B/b ; F/f) and is test-crossed with a homozygous recessive type (b/b ; f/f). (where B = black body; b = brown body; F = forked bristles; f = unforked bristles.) The results are: black, forked 230 black, unforked 210 brown, forked 240 brown, unforked 250 How many degrees of freedom would you use in this case? What would be the expected number for each...
