In mice the allele for blue coat color (B) pink coat color (b). The allele for long tail (T) is dominant of the allele for short tail (t).

1) If alleles of the two genes Assort Independently, what types of gametes will BbTt mice produce? What is the expected frequency of each gamete among all gametes produced?

Expert Solution

Since the alleles of two genes assort independently means that the assortment of genes of one pair doesn't depend upon the other gene pair during the process of gametogenesis. This results in production of offspring with new combination of characters.

BbTt will produce 4 different type of gametes having one allele of each of the gene(gametes are haploid) so the different gametes possible are BT, Bt, bt, bT. Because there is equal probability( 1/2)that the gamete will recieve one allele of one gene(coat color) and another allele of the second gene(tail) By multiplication rule (1/2 for blue/pink * 1/2 for long tail or short tail) = 1/4 frequency of each type of gamete.

Please rate my answer positively if u got your doubt solved. It will help me a lot.

In mice the allele for black coat color (B) is dominant to the allele for white coat color (b). The allele for long tail (T) is dominant to the allele for short tail (t). For the same cross: BbTt x bbTt a. Using the Probability Method illustrated in lecture, break the complex two-gene cross into two simple single-gene crosses (note that the Probability Method can be used if it is known that the alleles of the different genes Assort...

In dogs, the allele for black coat color (B) is dominant to the allele for brown coat color (b). But if a dog has two copies of the recessive allele for a pigment-depositing gene (e), it can only have yellow coat color. In a cross of two doubly heterozygous black dogs (BbEe x BbEe), what fraction of the next generation would we expect to be yellow? WHY? a.1/8 b.1/4 c.2/3 d.3/16

In cats, the allele for black coat color is codominant with the allele for yellow coat...

In cats, the allele for black coat color is codominant with the allele for yellow coat color, and is located on the X chromosome. If a cat gets alleles for black and yellow coat, it will have a mottled coat that contains both yellow and black coloring known as Tortoise shell. A tortoise shell female mates with a yellow male. a) What is the genotype of each parent? b) Draw a Punnett square that shows this cross. c) What is...

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.

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...

QUESTION 1 In mice, an allele for brown eyes (B) is dominant over an allele for apricot eyes (b). At an independently assorting locus, an allele for tan coat color (t) is recessive to an allele for black coat color (T). A mouse that is homozygous for brown eyes and black coat is crossed with a mouse having apricot eyes and a tan coat. The resulting F1 mice are crossed to produce the F2. a. Diagram the cross, including the...
