When you cross 2 heterozygous black cats (Bb) the expected mendelian phenotypic ratio of black (Bb) to gray (bb) offspring is:
B:G = 2:1
B:G= 3:1
B:G=1:3
B:G= 1:1
or can't be calculated

17. In cats, yellow fur is dominant to black fur. The heterozygous tortoise-shell" or "calico" condition is exhibited only by the female. The fur trait is sex-linked. What offspring (genotypes, phenotypes and frequencies) would you expect from the cross of a black male with a yellow female? What kinds of offspring would you expect to result from the cross of a black male with a tortoise-shell female? How about the cross of two tortoise-shell animals?! dong

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

Question 3 1 pts The color of chickens is determined by gene B, such that BB=black, Bb = gray, and bb = white. A second gene R controls comb shape, with dominant rose and recessive single comb. If a white single-combed chicken is mated with a gray chicken that is heterozygous for rose comb, what fraction of the offspring will be gray with rose comb? 1/4 9/16 1/8 O 3/8 1/16

Observing the phenotypic ratio of the offspring generation of a mated pair can increase our understanding of inheritance of traits. In wolves, gray fur and yellow eyes are dominant, black fur and blue eyes are recessive, and both traits are governed by simple (complete) dominance In the Ely, MN area there exists an alpha pair: a male dihybrid (double heterozygote) wolf displaying both dominant phenotypes mated with a female wolf recessive for both traits. Researchers hypothesize the two genes (fur...

If you test cross a purple bird that is heterozygous at one, but
not both loci, what are the possible phenotypic outcomes for the
offspring?
for each outcome give the genotype of the cross (both purple and
the testcross parent phenotypes- and the phenotypic ratio expected
in the offspring from that cross.

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...
