White is due to a dominant gene W, while black is due to its recessive allele. What is the GENOTYPE of: 1) a homozygous dominant individual, 2) a heterozygous individual, and 3) a homozygous recessive individual? (4 points)
1- WW
2-Ww
3-ww
Note- homozygous means two same , heterozygous means two different . Therefre we know which is recessive and which is dominant already to put at equation.
White is due to a dominant gene W, while black is due to its recessive allele....
coat color is due to a dominant allele (W), black coat color to its recessive allele unnett squares for each of the following crosses and answer the questions. 2. In sheep, white tw). Construct P d frequency fo a. A black sheep crossed to a black sheep. List the genotypes, phenotypes, an each of the offspring b. A white sheep, the product of a black x white cross, is crossed with a black sheep. List the genotypes, phenotypes, and frequency...
In maize (corn) plants, a dominant allele I inhibits kernel color, while the recessive allele i permits color when homozygous. At a different locus, the dominant allele P causes purple kernel color, while the homozygous recessive genotype pp causes red kernels. If plants heterozygous at both loci are crossed, what will be the phenotypic ratio of the offspring?
Black hair color in rabbits is due to the inheritance of the completely dominant allele B, while rabbits homozygous for the recessive allele b are white. If two black haired heterozygotes mate and produce a litter of 3 bunnies. What is the probability that the first bunny is white? 1.00 0.75 0.50 0.25 What is the probability that the first bunny is white, the second is black, and the third is white? 3/64 1/32 1/64 1/16 1/8
In horses, the color black is due to a dominant allele (B) and chestnut color is due to a recessive allele (b) of the same gene. The trotting gate is due to a dominant allele (T) and the pacing gate is due to the recessive allele (t) of the same gene. These two genes are located on different chromosomes. A homozygous black pacer horse mates with a homozygous, chestnut trotting horse and they have a daughter. a. What are the...
An allele, W, for white wool is dominant over allele w, for black wool. In a sample of 800 sheep, 792 are white.. Calculate the following frequencies assuming that the population is in Hardy-Weinberg equilibrium. a) The frequency of the recessive allele: b) The frequency of the dominant allele: c) The frequency of the heterozygotes. d) The frequency of the dominant phenotype.
1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...
2. A recessive allele (e) is epistatic over the B gene locus, producing a golden cot homozygous (ee). Dogs that are homozygous dominant (EE) o determined by the B locus, either black (BB or Bb) or chocolate (bb). Answer the following qs regarding a cross a Labrador retriever with the genotype Bb Ee and a Labrador retriever with the genotype Bb ee r heterozygous (Ee) will show the color A) What is the phenotype of dog 1? B) What is...
Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

1.
There is a gene for height in a species of pea plant that we will
call "T gene". We would denote the dominant allele for this gene as
_____ and the recessive allele as _____. A homozygous dominant
individual's genotype would be _____, a homozygous recessive
individual's genotype would be _____, and a heterozygous
individual's genotype would be _____.
2. If this gene for height in pea plants shows complete
dominance (where the dominant allele...
1) (4 pts) Black hair in rabbits is determined by a dominant allele, B, and white hair by homozygosity for a recessive allele, b. Two heterozygous rabbits mate and produce a litter of seven offspring. With what frequency would we expect to find: a) four whites and three black offspring? b) one white and six black offspring?
