Genetics - dihybrid crosses in Drosophila
1.
A. Diagram the cross: a male fly expressing white (w) on the X chromosome, vestigial wings (vg) on chromosome 2 and sepia eyes (se) on chromosome three with a female that is heterozygous for all 3 traits.

B. What proportion of the progeny from the cross above will express the vestigial trait, but not white or sepia. Consider using branching.

I think I have figured out part a -- just wanting to check work. Based off part a ...for part B I got 9/64 as my answer. Please check my work & show your work...I will give high rating.

A phenotypically wilptype F1 female fruit fly that was heterozygous for genes controlling body color and wing length was crossed to a homozygous mutant male tester with black body (mutant allele b) and vestigial wings (mutant allele vg). a.

"The orange locus in cats is located on the X chromosome. In females, XoXo results in orange cats and X+X+ results in black cats When a female is heterozygous XoX+, they express both colors in patches due to a phenomenon called X-inactivation in which one X in every cell is inactivated. These females are called calico or tortoiseshell, depending on the presence of white spots. Male cats are either orange (XoY) or black (X+Y). A cross between a black female...

Probability and Genetics Lab In heredity, we are concerned with the occurrence, every time an egg is fertilized, of the probability that a particular gene or chromosome will be passed on through the egg, or through the sperm, to the offspring. As you know, genes and chromosomes are present in pairs in each individual, and segregate as they go into the gametes (egg and sperm). There are two possible genes (alleles) that the egg or sperm might obtain from each...
