If a fruit fly that has long wings and a gray body (LIGG) mated with another fruit fly that has long wings and a gray body (LIGG), what would be the phenotypic ratio of their offspring? Also, list the different phenotypes. Do the cross! L=long wings, l-short wings, G-gray body, g=black body. 6) Phenotypic ratio: Different phenotypes:

Gene A converts compound A (white) to compound B (blue). Gene B converts compound B to compound C (purple). These compounds determine the color of the individual. In a self cross of AaBb individuals, what proportion of white to purple offspring should be seen? 3 white : 1 purple 3 white : 4 purple 4 white : 3 purple 1 white : 3 purple 4 white : 9 purple
A wild-type fruit fly (heterozygous for gray body color and red eyes) is mated with a black fruit fly with purple eyes. The offspring are wildtype, 721; black purple, 751; gray purple, 49; black red, 45. What is the recombination frequency between these genes for body color and eye color? Using information from problem 3, what fruit flies (genotypes and phenotypes) would you mate to determine the order of the body color, wing size, and eye color genes on the chromosome?
In swallowtail butterflies, let's pretend that the R gene codes for coloring on the forewing. The R1 allele, which codes for red color, is dominant to the R2 allele, which codes for white color. If R1 is a recessive lethal allele, what phenotypic ratio would you expect when crossing two swallowtails with red forewings? 1 red : 2 white 1 red : 3 white 3 red : 1 white there is not enough information given to answer this question 1 red : 1 white 2 red : 1 white

What is the expected phenotypic ratio among the offspring?
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?

A walnut comb rooster is mated to three hens. Hen A, which has a walnut comb, has offspring in the ratio of 3 walnut to 1 rose. Hen B, which has a pea comb, has offspring in the ratio of 3 walnut to 3 pea to 1 rose to 1 single. Hen C, which has a walnut comb, has only walnut comb offspring. What are the genotypes of the rooster and the three hens?
Imagine that you are performing a cross involving seed color in garden pea plants.
