In rabbits, white fur colour (W) is dominant over black fur colour (w), and upright ears (U) are dominant over floppy ears (u). The two genes are on different chromosomes.  A baby rabbit is called a kit. A heterozygous white rabbit with floppy ears mated with a black rabbit with heterozygous upright ears. What is the probability of having a black kit with upright or floppy ears? Select one: a. 0.25 b. 0.13 c. 0.50 d. 0.06

In pea plants, green color (G) is dominant to albino (g). If we cross two pea plants that are heterozygous for color, what would be the expected phenotype ratio of the offspring? Do the Punnett square and write the phenotypic ratio in the space below

In Labrador retrievers, two genes determine fur color: the E gene and the B gene.  Black fur (B) is dominant to brown fur (b).  However, the presence of (ee) will overshadow and create a puppy with yellow fur.  Create a Punnett square crossing 2 Labs that are heterozygous for both genes.  What are the resulting phenotypes?  Don’t forget to take epistasis into account!

In Thomas Hunt Morgan's experiments examining the transmission of eye color in fruit-flies, he observed that when he crossed heterozyYgous red-eyed females to red-eyed males, 1/2 of the male offspring were white-eyed, while all of the female offspring are red-eved, Which of the following best explains the results? 1/2 of the male offspring inherit a white-eye color allele from their heterozygous mothers. Since there is no eye color gene on the Y chromosome, their eyes are white. 1/2 of the male offspring inherit a Y-chromosome from their fathers. Since there is no eye color gene on the Y chromosome, their eyes are white. All of the female offspring inherit a dominant, red-eyed allele from their mothers A 3 to 1 ratio of dominant to recessive offspring are expected in a single factor cross
