Chapter 16.6, Problem 1TYK
Summary Introduction
Introduction:
In a fruit fly, two genes are linked on the same chromosome. Two individuals having the genotypes AABB and AaBb are crossed with each other. Then the female offspring having AaBb genotype is crossed with a male having a genotype of aabb.

You are looking at a maternal effect gene that comes in 2 alleles, B (brown) is dominant and b(gray) is recessive. What are the phenotypic ratios of offspring for the following crosses?a. BB female x bb maleb. bb female x BB malec. bb female x Bb maled. Bb female x Bb male
You are looking at a maternal effect gene that comes in 2 alleles, B (brown) is dominant and b (gray) is recessive. What are the phenotypic ratios of offspring for the following crosses?
BB female x bb male
bb female x BB male
bb female x Bb male
Bb female x Bb male
Two genes, A and B, are 10 map units apart along the same chromosome. A cross was made between AAbb and aaBB individuals to produce AaBb F1 offspring. The F1 offspring were then crossed to aabb individuals to yield an F2 generation. What would be the genotype(s) of F2 offspring that carry recombinant chromosomes? (Note: recombinant chromosomes are the product of crossing over). What percentage of F2 offspring would be Aabb?

- When crossing a true breeding white mouse with a true breeding brown mouse your friend tells you she recovered all black mice. But then when she crosses the F1 mice to each other she recovered 28 black mice, 8 brown mice, and 13 white mice. Can you help her explain these results? (Type out the cross and include genotypes of as many mice as possible. What phrase best describes this phenomenon? How many genes are involved are they linked or unlinked? Etc.)arrow_forwardGreen color in corn plant is controlled by a pair of genes. Give the genotype and phenotype of the offspring from the following crosses:a. GG x Ggb. Gg x Ggc.

- The presence of horns in cattle is controlled by a single gene. The hornless (H) condition is dominant over the horned (h) condition. A hornless cow was crossed repeatedly with the same horned bull. The following results were obtained with the F1 offspring: 8 hornless, 7 horned.

The following progeny are obtained: round, pink – 440 round, white – 76 wrinkled, pink - 84 wrinkled, white - 400 What is the distance (in map units) between the two genes in question? Your answer should be a single whole number between 0 and 50. Choose 50 if you think the genes are not linked.arrow_forwardIn sweet peas, gene C or P alone produces white flowers, the purple colour being due to the presence of both these factors.
