Homework Answers
a)dominant alleles are those which expresses its traits even in presence of an alternative allele i.e in heterozygous condition. now, here when cross is done in white and black cat they gave f1 generetion (i.e first filiial generation ) black cats here the black color is dominant over white color.
b) the recessive allele white is designated with small letter whereas dominant allele is designated by capital letter so here dominant allele is black designated by 'B' whereas recessive allele white is designated as 'b'.
c) genotype of black cat is BB or Bb whereas for white is bb and that of f1 is Bb.
d)

In a cross between a black and a white guinea pig, all members of the F1 generation are black. The F2 generation is made up of approximately 3/4 black and 1/4 white guinea pigs. A. Based on this cross, which trait is dominant and which is recessive? What information lead you to your conclusion? B. Diagram this cross, showing the genotypes and phenotypes of parental, F1 and F2 generations. C. What will the offspring be like if two F2 generation...

A guinea pig with black fur was bred to one with brown fur and all offspring na When two of these F1 offspring were bred, some of the resulting F2 progeny while others were black. a.

Determine the F1 generation of a cross between plants with the following genotypes: rrPp and RrPP. Create a Punnett square with the allelic combinations of rrPp on the x axis and RrPP on the y axis. Enter the possible combinations in the 16 blank, middle squares. Calculate the genotypic ratio for the F1 generation. Calculate the phenotype ratios for the F1 generation and record the phenotypic ratio. I know this is more than one question and don't expect you to...

6. In tigers, a dominant allele (W) is responsible for the expression of the normal orange pigment. Individuals that inherit twe recessive alleles (w) lack the normal orange pigment in their fur, appearing white with black stripes. A pair of normally colored parewis produces a cub that is white with black stripes and scab that is orange with black stripes. What are the possible genotypes of the cube? b. What are the possible genotypes of the parents? 6. Explain your...

In hogs, and allele that produces a white belt around the animals body (W) is dominant over its allele for a uniformly colored body (w). The dominant allele of another gene (F) produces a fusion of the two hoofs on each foot. Suppose a uniformly-colored hog homozygous with fused hoofs is mated with a normal-footed homozygous for the belted character. what are the genotypes of the parents? belted parent: Uniformly-colored parent: What are the genotypic and phenotypic ratios in the...

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...

2. In certain cats, tail length-long, short, manx (no tail) - is determined by a gene that demonstrates incomplete dominance. a. Make up letters to represent the long & manx alleles. b. Give the genotypes for each tail type. Long-tailed Short-tailed Manx c. Construct a Punnett square to illustrate a cross between a short-tailed cat and a man. What is the probability that the resulting kittens will be manx? Activity 3: Codominance 1. In codominance, the symbols for alleles are...

Just answer Part B
While working with a type of beetle that is normally smooth, large, and white, you discover three mutations that lead to the recessive phenotypes bumpy, small, and grey, respectively. You cross true- breeding smooth white beetles to true-breeding bumpy grey beetles and get all smooth white F1 beetles. Then you cross the F1 beetles to true-breeding bumpy grey beetles and, after analyzing 800 F2s, calculate a map distance of 5 M between the smoothness and color...
