Wild horses can have short or long manes and brown or green eyes. Mane phenotype is controlled by a single gene with two alleles, M (long mane) and m (short mane), where M is dominant to m. The eye phenotype is also controlled by a single gene with two alleles, B (brown eyes) and b (green eyes), where B is dominant to b. The mane and eye phenotype genes assort independently. a. In the cross MmBb x mmBb, what is the probability of a foal having a short mane and green eyes, or, a short mane and brown eyes?b. In the cross MMBb x Mmbb, what is the probability of a foal having a long mane and green eyes, or, a long mane and brown eyes?
please explain.
The answer to the following question are
A. Probability of short mane with either brown or green eyes is 1/2
B . Probability of long mane with either green or brown eyes is 1
For explanation
Hope you find this helpful thank you ☺️

The allele se gives Drosophila a sepia body and se+ gives brown,
the wild-type phenotype. The allele ro of a separate gene gives
rough eyes and ro+ gives smooth eyes, the wild-type phenotype. The
allele ss of a third gene gives flies without thorax spines and ss+
gives flies with thorax spines, the wild-type phenotype.
When females heterozygous for each of these genes were
testcrossed with sepia, rough, spineless males, the following
classes and numbers of progeny were obtained:

In flies, red eyes are dominant to brown eyes, while long wings are dominant to dumpy wings. You will cross a true-breeding fly with red eyes & dumpy wings to a true-breeding fly with brown eyes & long wings. a. What genotype & phenotype do you expect in the F1 generation? b. Draw a Punnett Square which represents the F2 generation & give phenotypic ratios.

3. A father with brown eyes marries a woman with blue eyes, and all of their children have brown eyes. (We are going to assume that this is a monogenetic trait, but in reality, t is not.) a. Assign symbols for the possible alleles. Brown:_ b. Which allele is dominant? Complete a Punnett square for the cross that results in all the offspring (the F1 generation) Blue having a brown-eyed phenotype C. What are the...
The genes for sepia eye color, short bristles, and dark body coloration are on the same chromosome of Drosophila melanogaster. Each gene has two alleles: wild type, which is dominant, or mutant, which is recessive. se+ is dominant and causes red eyes; se is recessive and causes sepia eyes sb+ is dominant and causes long bristles; sb is recessive and causes short bristles b+ is dominant and causes gray body coloration; b is recessive and causes dark...
1. In dogs, brown hair (B) is dominant over yellow hair (b), green eyes (G) are dominant over blue eyes (g), long tails (L) are dominant to short tails (l), and drooling (D) is dominant over not drooling (d). List all the gametes produced by a dog with the genotype BBGgLldd. 2. The following genotypes mate: bbGGLlDd x BBggLlDd What is the probability of producing a dog with the following genotype: BbGgLLDD BbGgllDd BBggLlDd

Dumpy flies have short, stubby bodies. A test cross is performed to determine whether this phenotype is the result of a single dominant allele. The following results are obtained for one such cross: Dumpy offspring 124 Wild type offspring 110 Use the Chi squared test to determine whether or not the results are compatible with the hypothesis of single gene inheritance
Let's say you have a pea plant that has the dominant traits for Tall stalks and Yellow seeds (TY). You want to know if this plant is homozygous for these traits, or heterozygous. What would you cross it with, and what is this called? A Monohybrid cross: TY X TY a plant with the same phenotype B. Dihybrid cross: a plant with a different trait (pink flowers and tall stalks) C. Test-cross; a plant homozygous for the recessive alleles: short...
BIO340 Recitation 5 Spring 2020 Your professor is having you look at two genes in Drosophila fruit flies to determine experimentally whether they are linked. One trait is eye color and two alleles are present at the gene: se+ is the wild-type allele for red eyes, and se is the mutant, recessive allele for sepia eyes. The second trait is body color and two alleles are present at this gene: e+ is the wild-type allele for grey body, and e...
