of eye pigment) is inherited as a sex-linked recessive. A
man with ocular albinism marries a woman who neither has
this trait nor is a carrier. What would you predict about
their offspring concerning this trait?

what is the pairing rule for deoxyribonucleic acid?
The weight of the fruit of one variety of squashes is determined by three pairs of genes: AABBCC produces 6 lb squashes and aabbcc produces 3 lb squashes. Each dominant allele adds 1/2 lb tothe base weight (3 lb). If a pure breeding line that produced 6 lb squashes was crossed with a pure breeding line that produced 3 lb squashes, what would be the phenotypic ratio of the F1 and the F2?

In horses, B = black, b = brown, T = trotter, t = pacer. A black pacer mated to a brown trotter produces a black trotter offspring year after year. What are the probable genotypes?

The gene for tallness (T) is dominant over the gene for shortness (t) in pea plants. A homozygous dominant pea plant is crossed with a heterozygous pea plant, and 200 seeds are produced. Approximately how many of these seeds can be expected to produce plants that are homozygous dominant?
How do you recognise that it is deoxyribose nucleic acid?
