biology (genetics) : Coat color in a given strain of dogs is determined by two independent genes. A dominant gene (D) determines white coat, and its recessive alleles (d) gives colored coat. In the presence of the homozygous recessive dd the coat color is black due to the presence of another dominant gene (B), or brown due to its recessive allele (b). Assuming a random mating population of dogs had the following phenotypic distribution: 448 white, 168 black, and 84 brown, find the frequency of each gene in the population.

Imagine that hair color in cats is controlled by one gene with two alleles: "T" and "t". "T" codes for grey fur and is completely dominant "t" codes for white fur and is recessive If a cat with the genotype TT had kittens with a white cat, what color of fur will their offspring have? Grey and White spots White Grey half the kittens have white fur, and the other half will have grey fur
Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele. In a college genetics class, the professor takes a tally of students who have curly hair and of students with straight hair. In this class of 131 students, 52 have curly hair. Calculate the frequency of the dominant allele, C, and the heterozygous genotype, Cc. Express the frequencies in decimal form rounded to the nearest thousandth. Assume the class is in Hardy-Weinberg equilibrium for this trait. frequency of C: | frequency of Cc: about us careers privacy policy terms of use contact us help
The color of spaniel dogs is controlled by a couple of alleles : B (dominant) leads to black hair [B], b to a tawny color [T]. In second independent gene, the dominant S allele gives a uniform colored fur [U] and the recessive s allele to a speckled coat [S]. A pure lineage uniformly black male is mated to a tawny speckled female. Among F2 animals, a uniformly black dog is crossed with a tawny speckled bitch. The progeny gives 1/4 [BU], 1/4 [TU], 1/4 [SB], 1/4 [ST]. How is this type of cross called and what is its goal? What are the genotypes of their parents?
In an example of recessive epistasis the deposition of pigment into hair follicles of the Labrador Retriever is governed by a dominant gene (C) and lack of deposition by its recessive allele (c). Lack of pigment deposition produces a yellow coat color. The color of pigment is governed by an independently assorting hypostatic gene, the dominant allele (B) produces black pigment and its recessive allele (b) produces brown. What coat color ratio is expected from the cross of a brown dog (bbCc) to a black dog (BbCc)? 3/8 black, 1/8 brown, 1/2 yellow 3/8 black, 3/8 brown, 1/4 yellow 1/2 brown, 1/2 black 1/2 black, 1/4 brown, 1/4 yellow 1/4 black, 1/4 brown, 1/2 yellow
In a certain breed of dogs, a gene (L) codes for hair length. The dominant trait is short hair and the recessive is long hair. Suppose a heterozygous female dog and a homozygous recessive male dog mate. What is the male dog’s genotype and the female dog’s genotype? What is the male dog’s phenotype and the female dog’s phenotype? What will be the genotypic ratio for the offspring from these dogs? What will be the phenotypic ratio for the offspring from these dogs?
Consider this hypothetical example. Bluegills can either have green eyes or brown eyes. The trait is controlled by a single gene. Bluegills can either have long or short fins. This trait is controlled by a single gene that is on a different chromosome from the eye color gene. Having green eyes is dominant (G), while having brown eyes is recessive (g). Having long fins is dominant (L), while having short fins is recessive (I). Your not-so-famous instructor will mate a male and female that both are heterozygous for eye color and heterozygous for fin length. What phenotypic ratio is expected from this mating? O 1:1:1:1 O 1:2:1:2:4:2:1:2:1 O 3:1 O 9:3:3:1
Please read the scenario below, and then answer the question (in bold) that follows. In cats, the allele (B) produces a black coat color and the allele (b) produces a yellow coat color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell coat color. The alleles (B) and (b) are also sex-linked (i.e., they are carried on the X chromosome), and cats possess an XX-XY sex determination system, like humans. If a female cat with a tortoise shell coat mated with a male cat who had a yellow coat... What gametes would be produced by the female (i.e., mother) cat? a. XBXb b. XB and Xb c. B and b d. Xb and Y e. None of the above

Consider this hypothetical example. Bluegills can either have green eyes or brown eyes. The trait is controlled by a single gene. Bluegills can either have long or short fins. This trait is controlled by a single gene that is on a different chromosome from the eye color gene. Having green eyes is dominant (G), while having brown eyes is recessive (g). Having long fins is dominant (L), while having short fins is recessive (1). Your not-so-famous instructor will mate a male and female that both are heterozygous for eye color and heterozygous for fin length.

In rural northeast Kansas domesticated cats are becoming wild, and biologists are observing that wildcats occur in three colors. Fur color is controlled by a single gene that exhibits incomplete dominance. A homozygous dominant cat is blue (BB), a homozygous recessive cat is red (bb), and a heterozygous wildcat will be purple (Bb). What would be the expected phenotypes of the offspring if a blue wildcat mates with a red wildcat? Develop a Punnett square and list the genotypes as well.
