Parental cross: Homozygous brown (BBRR) X Homozygous white (bb
rr)
F1 progeny: BbRr
F1 backcross: BbRr X bbrr
Gametes: BR Br bR br X br
Progeny: BbRr Bbrr bbRr bbrr
F2 phenotypic ratio = 1:1:1:1
F2 genotypic ratio = 1:1:1:1
1 = Brown (B_R_) = BbRr
1 = Blue (B_rr) = Bbrr
1 = Red (bb R_) = bbRr
1 = White (bbrr) = bbrr

can i get help with these 2 problems?
In the yawncat (a rare hypothetical animal), the black coat color allele B is dominant to the brown allele b, but the B locus can only be expressed if the animal has an mm genotype at a second gene locus. Animals that are M_are yellow regardless of which allele from the B locus is present. a. A mating between a yellow-tailed male yawncat and a brown-tailed female yawncat produces 16 offspring with...

18. Coat color in shorthorn cattle is determined by incomplete dominance. Individuals homozygous for the red allele (CRC) have red fur, individuals homozygous for the white allele (CWCW) have white fur, and heterozygous individuals (CCW) are roan (brown and white). A second gene in these cattle determines if they will have horns. The horned allele (H) is dominant to hornless (h). Predict the genotypic and phenotypic ratios of the offspring if a heterozygous horned-roan bullis crossed with a hornless -...

In wild petunias, the allele for red flower color (R) is dominant over the allele for white flower color (r). We sample a population and find 240 plants have white flowers and 85 have red flowers. If the population is in HWE, what are the allele frequencies of R and r in this population? How many of the 85 plants that have red flowers are homozygous and how many are heterozygous at the flower color locus?

Question6 1 pts Recall that, in a type of mouse, fur color is determined by alleles at one gene locus; allele A for brown fur and allele a for white. Height is determined by another gene locus; allele B for tall and allele b for short. Each uppercase allele is completely dominant to their respective lower case allele. The 2 gene loci sort or segregate independently. There are no interactions. Mouse 1 (genotype AaBb) mates with mouse 2 (genotype AaBb)...

In wild petunias, the allele for red flower color (R) is dominant over the allele for white flower color (r). We sample a population and find 750 plants have white flowers and 270 have red flowers. If the population is in HWE, what are the allele frequencies of R and r in this population? How many of the 270 plants that have red flowers are homozygous and how many are heterozygous at the flower color locus? Show your work and...

You are studying the genetic basis of the difference in the color of two species of flowers - one that has | red flowers and one that has white. You have determined that this difference is due to a single gene and red (R) is completely dominant to white) minant to white (C). You have also identified a candidate gene (R-locus) that, while there are no differences in the coding region between red and white flowers, the locus shows a...

In humans, brown (B) eye color is dominant to blue (b) eye color and brown (H) hair color is dominant to red (h) hair color. [Assume single-gene traits] Of only the offspring that have brown eyes and brown hair (B_H_, where dash indicates that the individual could be either homozygous or heterozygous for the dominant allele), what proportion are expected to have a genotype that is heterozygous for one of the traits but homozygous for the other trait? A) 1/4...

2. In Labrador dogs, there are 2 loci that determine coat color. The first locus, B is dominant to b. At least one B allele will produce black coat color, while the bb genotype produces a chocolate coat color. This first locus also determines nose color in Labradors: B_ black noses, and bb brown noses. The second locus has a genotype, ee, that is epistatic in nature. Any Labrador with an ee genotype will be yellow. A genotype containing at...

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...

Question 25 2 pts In dragons, the dominant allele R causes solid tail color, and the recessive alleler results in white spots on a colored background. The black coat color allele Bis dominant to the brown allele b, but these genes can only be expressed if the animal has an mm genotype at a third gene locus. Animals that are M are yellow regardless of which allele from the Blocus is present. A mating between a solid yellow-tailed male dragon...
