3)Assume that green eyes in humans are dominant to blue eyes. Further assume that these are the only two colors and that human eye color follows Mendel’s rules. A true-breeding greeneyed male produces offspring with a true-breeding blue-eyed female. What color eyes will the offspring have?
Homework Answers
Green colour is dominant over blue colour.
Suppose green colour is coded by gene G and blue colour is coded by g.
True breeding green eye will have GG genotype and true breeding blue eye will have gg genotype.
Croos between GG x gg will have Gg genotype offsprings and since G is dominant over g, offsprings will have green colour eyes.

For the purpose of this problem assume that in humans eye color is controlled by a single gene and that the allele for brown eyes is dominant to the blue-eye allele. Two brown-eyed parents planning a pregnancy already have a blue-eyed daughter. PLEASE NOTE: gender (being male or female) is a SECOND trait (like a second Punnett square), but no need for a Punnett square because the chance that an offspring will be male or female is always 1/2. Assign...

29, In fruit flies, red eyes are dominant over white eyes. The gene for eye color (R) is found on the X chromosome (X^R). Females have 2 X chromosomes and males are XY. Fill in the following (case sensitive!): Genotype of a white eyed female: Possible female gametes; separate gametes with a comma (,): Genotype of a red eyed male: Possible male gametes; separate gametes with a comma (,): In fruit flies, red eyes are dominant over white eyes. The...

In humans, brown (B) eye color is dominant to blue (b) eye color and brown (H) hair color is dominant to red (h) hair color. [Assume single-gene traits] Question: Two individuals, who are both heterozygous for eye and hair color, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring if the genes are unlinked? A) 9/16 will have brown eyes and red hair B) 9/16 will have blue eyes and red hair...

A frog biologist breeds true-breeding female frogs that have green bodies and red eyes with true-breeding male frogs with yellow bodies and blue eyes. All male offspring have green bodies and ted eyes, all female offspring have yellow bodies and red eyes. Using your own clearly defined alleles, give the genotypes for the parent frogs and the male and female offspring.

genetics problem:
5. On a small island, 235 mating individuals are all homozygous for brown eyes. An epidemic wipes out all but 10 young women, 2 young men, and two elderly women (both >70 years old). A boatload of foreigners arrives; the foreign population consists of six heterozygous brown-eyed young women, four homozygous brown-eyed young men, and 10 blue-eyed young men. Assuming that eye color is controlled by a single locus with the brown allele being dominant (blatantly incorrect, but...

A frog biologist breeds true-breeding female frogs that have green bodies and red eyes with true-breeding male frogs with yellow bodies and blue eyes. All male offsprings have green bodies and red eyes, all female offsprings have yellow bodies and red eyes. Question : Using your own clearly defined alleles, give the genotypes for the parent frogs and the male and female offspring.

what is b and c?
1) In marsh lizards rough scale (st) is completely dominant to smooth scale (s). Eye colour is determined by an incompletely dominant sex-linked allele and can be blue (b+), or yellow (b) with the heterozygote giving green eyes. A further gene (t) controls tail formation giving rise to a bent tail in homozygotes, t allele is dominant with respect to straight tail formation but is a recessive lethal. Parental genotypes of following phenotypes: A smooth,...
