1. In dogs, brown hair (B) is dominant over yellow hair (b), green eyes (G) are...
In dogs, short hair is dominant over long hair, and dark coat
color is dominant over albino fur. Assuming that these effects are
caused by two independently sorting genes, what will be the result
of the following cross? Create a Punnet square and show your

2. In tomatoes, the gene for round fruit is dominant to the gene for long fruit. A homozygous round fruit plant was crossed with a long fruit plant. Show the genotype of the two...
in labrador retrievers, black hair pigment (b) is dominant to brown hair pigment (b); e allows pigment to be deposited in the hairs, while ee individuals deposit no pigment in their hair and appear yellow. if two black labs mate and their litter includes black, brown, and yellow puppies, what are the genotypes of the two black labs? Draw a punnett square showing the gametes possible from these black labs andthe genotypes expected in their offsprings. Assume independent assortment for...
1. A monogenic trait (hair color) is controlled by the B locus with dominant B (brown) and recessive b (red) alleles. Another monogenic trait (hair texture) is controlled by the C locus with dominant C (curly hair) and recessive c (straight hair). a) What are the possible classes of genotypes with these two loci? b) What are the possible genotypes with these two loci? c) What are the possible genotype(s) of a person with brown hair? d) What are the...
In guinea pigs, the allele for short hair is dominant over long hair. If a heterozygous short hair guinea pig is crossed with another heterozygous short hair guinea pig, what is the probability of an offspring having long hair? In pea plants purple flower allele is dominant to white flower alleles. If a homozygous purple flower plant is crossed with a white flower plant, what percent of their offspring would you expect to be purple? Straight fur (S) is dominant...
In humans, brown (B) eye color is dominant to blue (b) eye color and brown (H) hair color is dominant to red (h) hair color. [Assume single-gene traits] Question: Two individuals, who are both heterozygous for eye and hair color, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring if the genes are unlinked?

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...
In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female? B. b,...
The genes for dark eyes (black or brown) are usually dominant over genes for blue or gray eyes. A man with black eyes marries a woman with light gray eyes. They have two children, a boy with black eyes, and a girl with blue eyes. What are the genotypes of the man, his wife, and both children?
