Textbook Question
Chapter 12, Problem 18TYK
Design an Experiment Imagine that you are a breeder of Labrador retriever dogs. Labs can be black, chocolate brown, or yellow. Suppose that a yellow Lab is donated to you and you need to know its genotype. You have a range of dogs with known genotypes. What cross would you make to determine the genotype of the donated dog? Explain how the resulting puppies show you the Lab’s genotype.

Use the image below to answer the following questions.
Label the genotypes for ALL the family members in the pedigree above. Remember to use XX and XY when labeling.
What does it mean to be a carrier?
Why does Alexis have hemophilia?
Is hemophilia a sex-linked disease? What does that mean and how does this pedigree show you this?
You cross two wildtype (short-tailed) chipmunks, and collect a male offspring with a
particularly long tail, which you name Dale. Tail length is controlled by the gene T, which is a
maternally imprinted gene in chipmunks. Choose the best answers to complete the
following statements.
⚫ Dale's allele for a long tail was inherited from the
female
parent.
That parent did not express the long tail phenotype because the allele was inherited from
father
the parent's own
• If one of Dale's offspring inherits the long tail allele from him, it
either will or will not
express that phenotype.
Understand the the given genetic problem. Draw the Punnet square using a clean paper and analyze the results.
A cross between true breeding plants for red (R) flower and white (r) flower results to all red flowers in F1. Based on the results, red color is dominant while white color is recessive. Use Punnett square to show the result of genetic cross and analyze the results.

Two different genes control the expression of kernel colour in Mexican black corn: black pigment gene B and dotted pigment gene D. Gene B influences the expression of gene D. The dotted phenotype appears only when gene B is in the homozygous recessive state. A colourless variation occurs when both genes are homozygous recessive. After pure-breeding black-pigmented plants were crossed with colourless plants, all of the offspring were black-pigmented. What is the probability of dotted offspring being produced from the test cross described above? (Record your answer as a whole number percentage).
