Question

does someone know the answer for these questions? Thank you so much

3. In certain breeds of dogs, black color is dominant and red color is recessive. Solid color is dominant and spotting is recessive. A homozygous black male is crossed with a red-and-white spotted female. What is the probability of them producing a solid black puppy? 4. In horses, black color (B) dominates chestnut color (b). The trotting gait (T) dominates the pacing gait (t). A cross is made between a horse homozygous for black color and the pacing gait, and a horse homozygous for chestnut color and the trotting gait. List the probable genotype and phenotype of offspring resulting from the F2 generation. 5. Many animals and plants bear recessive alleles for albinism, a condition in which homozygous individuals completely lack any pigments. An albino plant lacks chlorophyll and is white. An albino person lacks melanin and has very pale skin, white blond hair and reddish eyes. If two normally pigmented people that are heterozygous for the albinism allele have children, what proportion of their offspring would be albino? 6. Black (B) involved in the synthesis of melanin in Labrador dogs is dominant over brown (b). A separate allele (E) is responsible for deposition of the pigment in the hair. Two recessive alleles (ee) result in failure of deposition and a lab with yellow fur will result. If you cross a homozygous black male (BB EE) with a homozygous yellow female (bb ee) what will be the F, and F2 combinations? 7. In humans, the condition for normal color vision dominates color blindness. Both genes are linked to the X chromosomes. A color-blind man marries a color-blind female. If they have a daughter, what are the chances that she will have normal vision?
