  1. In a population of mice, coat color is controlled by a gene locus with two alleles, B and W. BB mice are brown, BW are tan and WW mice are white.

What is this type of inheritance called?

In this population there are 20 brown mice 15 tan mice and 30 white mice. Calculate p and q for this population where p = the allele frequency of B and q = the allele frequency of W.

Solutions

Expert Solution

• Given example is type of " Incomplete dominance" inheritance.
• In this inheritance, neither allele is dominant and when a organism is heterozygous then it shows a third phenotype which is intermediate of other two phenotypes.
• In given question, heterozygous mice BW is showing coat colour tan, which is intermediate of brown and white.

The coat color in mink is controlled by two codominant alleles at a single locus. Red coat color is produced by the genotype R1R1, silver coat by the genotype R1R2, and platinum color by R2R2. White spotting of the coat is a recessive trait found with the genotype ss. Solid coat color is found with the S- genotype. Two crosses are made between mink. Cross 1 is the cross of a solid, silver mink to one that is solid, platinum....

  Suppose that a particular gene that controls coat color in dogs is controlled by four alleles in the population. These alleles are called cch (chinchilla dog), cd (white dog with dark eyes), cb (pale gray dog) and c (albino dog). The alleles are given from the most dominant to the most recessive. Let’s assume that a particular population of these dogs is in Hardy-Weinberg equilibrium. The allele frequencies for our four alleles are: cch = 0.37 cd = 0.23 cb...

a. In a pea plant, leaf color is controlled by a gene with two alleles: a dominant allele G for green leaves, and a recessive allele g for yellow leaves. A researcher crossed a plant with green leaves with a plant with yellow leaves. All the resulting offspring had green leaves. What were the genotypes of the two parental plants? (5 points) b.  Explain briefly what is a bottleneck effect and give two examples (the examples can be imaginary). (5 points)

The agouti locus in mice has three alleles: a is recessive and confers a black coat, A is dominant to a and confers an agouti coat, and AY is dominant to both and confers a yellow coat. AY is also a recessive lethal. In addition, the independently assorting c allele is recessive (to C) and prevents the mice from making any fur pigments at all, resulting in albinos. Two mice are crossed, and produce offspring in a ratio of 2...

1. In mice, one of the gene determining coat color is the A gene, which has multple alleles. two of these are an Allele for black hair (a) and allele for yellow hair (Ay) . (Ay) is completely dominant to a; however, for reasons that are unclear ( at least to me), AYAY mice always die before embroyic development is completed. a) two mice with yellow hair mate with each other. what are the genotype of the mice? b) for...

In Labrador retrievers coat color is controlled by two independently assorting loci. The B locus controls hair color; black (B) is dominant to chocolate (b). A second locus, E, allows for deposition of the color on the hairs. The homozygous recessive condition at this locus (ee) produces a yellow dog, regardless of whether the animal is BB, Bb, or bb. You discover that your female yellow Labrador is pregnant, and she delivers a litter of 5 black puppies, 2 chocolate...

Nail color in the North American sasquatch is controlled by a single gene with 2 alleles. The completely recessive allele (n) results in a yellow nail, while the dominant allele (N) results in a black nail. A female sasquatch with black nails mates with a male sasquatch with yellow nails. Two of their 5 offspring have yellow nails.             a. What are the genotypes of the male and female sasquatch? How do you know? B. Suppose one of the yellow-nailed...
