Black fur in mice is dominant to white fur. Short tails are dominant to long tails. A mouse that is heterozygous for both fur color and tail length is crossed with a white, long-tailed mouse. What would be the fraction of the offspring that would have both black fur and short tails?   1/16   3/16   1/4   1/2   9/16

Brown eye color is dominant to blue eye color. Individual A is heterozygous for brown eyes. Individiual B has brown eyes, and both his parents have brown eyes. Given this information, what is the probability that their baby will have blue eyes?

n mice coloring is determined by three alleles of the agouti gene.  AA, codes for agouti coloring, AT codes for black with tan belly, and AB codes for all black.  The dominance order is AA>AT>AB. What proportion of offspring are expected to be black with a tan belly from the following cross  ABAT x AAAT?     1/2     1/8     none     3/4     1/

In pea plants, flower color is determined by one gene with two alleles, with the allele coding for purple flowers (P) being dominant to the allele coding for white flowers (p). If two purple-flowered offspring resulting from a cross between homozygous dominant and white-flowered parents are crossed, what percentage of the progeny are expected to have the dominant phenotype?

A type of mouse may have round ears or pointed ears. A female mouse homozygous for pointed ears is crossed with a male mouse homozygous for round ears. All the male offspring have pointed ears and all the female offspring have round ears. When the F1 offspring are crossed with each other, the resulting F2 are produced in the following ratios:                                                   Males: 3 pointed : 1 rounded                                                  Females: 3 rounded : 1 pointed Explain the inheritance mechanism that produces these results and indicate the dominance relationship.

A fish with red eyes and yellow scales is crossed to a pure-breeding fish with brown eyes and orange scales, resulting in offspring having red eyes and yellow scales (50%) or brown eyes and yellow scales (50%). You cross the red eye/yellow scale offspring together, and the resulting offspring are as follows. How are these traits likely inherited Number of offspring 676-yellow/red 224-red/orange 224-brown/yellow 76-brown/orange

Three different genes determine the coat colour of cats. One of the genes controls the black-based coat colour. There are three alleles for black-based coat colour genes with the following order of dominance: black (B) > chocolate (bch) > cinnamon (bc). Two black cats were crossed. The offspring produced were three black kittens and one chocolate kitten. What is the probability of having a male chocolate kitten? Select one: a. 0.50 b. 0.25 c. 0.13 d. 0.06

In mice coloring is determined by three alleles of the agouti gene.  AA, codes for agouti coloring, AT codes for black with tan belly, and AB codes for all black.  The dominance order is AA>AT>AB. What proportion of offspring are expected to be black with a tan belly from the following cross  ABAT x AAAT?     1/8     none     3/4     1/4     1/2
