GENETICS PROBLEMS 1. The gene for widow's peak (W) is dominant to the gene for straight hairline (w). A male homozygote with widow's peak marries a female homozygote with straight hairline, what are the possible genotypic and phenotypic ratios of the F1 and F2 generations that may result from the union? Phenotype of Parents ………………………… x ………………………… Genotype of Parents ………………………… x ………………………… Genes in gametes ………………………… x ………………………… Genotype of F1 Generation ………………………… Phenotype of F1 Generation ………………………… Genes in F1 gametes ………………………… or ………………………… (Punnett Square)...

In mice, black fur (B) is dominant over brown fur (b). Breeding a brown mouse and a homozygous black mouse produces all black offspring. a. What is the genotype of the gametes produced by the brown-furred parent? ________________________________________________________ b. What is the genotype of the brown-furred parent? ________________________________________________________ c. What is the genotype of the black furred parent? ________________________________________________________ d. What is the genotype of the black-furred offspring? By convention, P stands for the parental generation. The offspring are called...

The results for the F2 progeny are shown for a F1 cross using
the two X-linked markers:
w+ and m+.
As shown in the figure, the F1 cross is between the following
two parents:
- a phenotypically wild-type (red eye, full wing), heterozygous
female: w+m+/wm
- a double mutant male (white eye, miniature wing):
wm/Y
Answer the following questions:
1) In the F1 cross, can you infer the genotype for the phenotype
in the female? Why or why not?
2)...

Question 12 only.
Punnett's square analysis for the parental cross r Rr Rr 9) If we used the above offspring (F1) in a new cross, what would be the genotypes and phenotypes of the offspring of the Fz generation? 10) What is the genotypic ratio of the F2 generation? 11) What is the phenotypic ratio of the F2 generation? 12) What would be the genotypic and phenotypic ratios of offspring from a cross between a homozygous recessive parent (r r)...

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall...

Check my work Genes A and B are so close together on the same chromosome that crossing-over occurs between A and B in only 1 in a million meioses. An AA bb individual mates with an aa BB individual to produce an F1 that is A b/ a B. If 100 progeny are observed, what genotypic ratio is expected in the gametes produced by the F1? Multiple Choice 1 AB:1Ab: 1 a 8:1 ab More parental A B and a...

2. The lubber grasshopper is a very large grasshopper, and is black with red and yellow stripes. Assume that red stripes are expressed from the homozygous RR genotype, yellow stripes from the homozygous rr genotype, and both from the heterozygous genotype. A. If two heterozygous grasshoppers were crossed, what would be the genotypic ratio of the F1 generation (RR:Rr:rr)? Fill in the Punnett square. B. What genotypes would be produced by crossing a grasshopper with both color stripes and one...

In a particular species of tomato plant, the plants can bear fruits of different colors. Suppose a researcher crosses a homozygous plant that bears white fruit with a different stock of homozygous plant that also bears white fruit. In the Fı generation, all of the fruits are red. Two Fı plants are then crossed and the F2 progeny are examined. The F2 generation contains 219 plants with red fruit and 173 with white fruit. Stepl: Determine if there is one...
