In hamsters, black fur (B) is dominant over brown fur (b) and long fur (L) is dominant over short fur (l).  A black, long furred female whose mother had brown fur and whose father had short fur is mated with a black, short furred male whose father had brown, long fur.  What is the probability that the first three offspring will have brown, long fur? What is the probability that the first offspring will have black, long fur? What is the probability that one of the first three offspring will have black, long fur and the other two brown, short fur?

a) colored, normal mated with white, normal, produced 29 colored, normal, and 10 colored waltzers. behavior is dominant over (n) for waltzing. Pairs of mice were mated and the following results obtained. In mice, the gene (C) for colored fur is dominant over its allele (c) for white. The gene (N) for normal on separate dominant genes located on different chromosomes. Normal vision and normal bones d. man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to are recessive traits. A man with cataracts and normal bones, whose father had normal eyes, married a What is the genotype of the man with cataracts and normal bones? woman firee from cataracts but with fragile bones. Her father had normal bones. 1. In What type of offspring might this couple expect? Phenotypes Genotypes What is the probability that their first child will: (a) be free from both abnormalities (b) have cataracts but not fragile bones (c) have fragile bones but not…

Please read the scenario below, and then answer the question (in bold) that follows. In cats, the allele (B) produces a black coat color and the allele (b) produces a yellow coat color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell coat color. The alleles (B) and (b) are also sex-linked (i.e., they are carried on the X chromosome), and cats possess an XX-XY sex determination system, like humans. If a female cat with a tortoise shell coat mated with a male cat who had a yellow coat... What percentage of their offspring will have tortoise shell coats?   a. 0%   b. 25%   c. 50%   d. 75%   e. 100%

In humans, free ear lobes (E) is dominant over attached ear lobes (e), and brown eyes (B) is dominantover blue eyes (b). A man with free ear lobes and brown eyes marries a woman with attached ear lobes andbrown eyes. Of four children, one has free ear lobes and brown eyes, one has free ear lobes and blue eyes,one has attached ear lobes and brown eyes, and one has attached ear lobes and blue eyes. Determine thegenotypes of the parents.
