2. the gamete that Sheilx can prealuce: c. What are the genotypes of the offipribg? Oftispeing with
fatch and no spotke Oftspring with no patch or spotss d. What gamete did Ash give the offippring?
Offipring with patch and no ipots: Ofispring with no patch or spots: c. Based on this information,
give the genotype of Ashi f. Drave a Puninets Square to illustrate the cross between Ash and
Sheila g. This cross would be an example of a cross. 9. In walleye (a species of fish), seale colour
and pattern are determined by two different genes located on different chromosomes. In
answering the following questions, use the letters G and g for scale colour and H and h for scale
pattetn. Tobin, a wallcye with yellow scales that had a motticd pattern, was bred with Crystal, a
walleye with bluc scales with a solid pattern. All of their children had yellow scales and a solid
pattern. a. Give the genotypes of the following: Tobin Crystal! Their children (the F1) Jeanette is al
walleye that is heterozygous for scale colour and homozygous recessive for pattern. b. What is
Jeannette's phenotype?c. Give the genotypes of all of the gametes that Jeanette could produce. d.
Jeanette was accidentally crossed with one of Tobin and Crystal's children. Draw a Punnett
square to illustrate this cross. c. Calculate the expected phenotypic frequencies among the
offspring of this cross. 10. In rats, the allele for kinky hair (h) is recessive to the allele for normal
hair (H), and the allele for short tail (t) is recessive to the allele for long tail (T). The genes for hair
kinkiness and tail length are found close togetber on the same chromosome (i.e., they are linked).
"Backalley Bob" is a rat who is heterozygous for both hair type and tail length. Bob's mother had
normal hair and a short tail, and was homozygous for both traits. Bob met and married "Riverboat
Rita," a kinky-haired, short-tailed rat. a. Give the genotype of each of the following: Backalley Bob:
Backalley Bob's mother: Riverboat Rita: b. Draw a Punnett square to illustrate the cross between
Backalley Bob and Riverboat Rita. Remember-the genes are linked. Assume that there is no
crossing over. c. Give the predicted genotypic ratio of the offspring of this cross, if there is no
crossing over. d. Draw a chromosome diagram to show Backalley Bob's cell in prophase I of
meiosis. Assume no crossovers have occurred. Label alleles on each chromatid you draw.
