Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?
Is Recombination in Human Mitochondrial DNA really possible?
Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child
How is co-dominance different from incomplete dominance
what are the genetical reasons behind obesity?
In cucumbers normal leaves (N) are dominant to curled leaves (n) and elongated fruit (L) is dominant to spherical fruit and these genes are linked on the same chromosome. If a pure-breeding normal-leaved, elongated fruit cucumber is crossed with a curled-leaved, spherical fruit cucumber, what will be the phenotype of the F1? the phenotypic ratio of the F2?
In snapdragons tallness (T) is dominant to dwarfness (t). Red flowers are produced by RR and white flowers by rr but the heterozygous Rr is pink. A dwarf red snapdragon is crossed to a homozygous tall plant with white flowers. What is the phenotypic ratio of the F1? the F2?
