The inheritance of height in man is a more complex phenomenon involving perhaps ten or more pairs of genes. The character of tallness is recessive to shortness, thus, an individual having the genotype of more dominant genes will have the phenotype of shortness. Because, this quantitative trait is controlled by multiple pairs of genes

Genetics is the biology of heredity, and geneticists are the scientists and researchers who study hereditary pro-cesses such as the inheritance of traits, distinctive charac-teristics, and diseases. Genetics considers the biochemical instructions that convey information from generation to generation. Tremendous strides in science and technology ...

The ability to taste PTC shows dominant inheritance and is controlled by a gene on chromosomes 7. This gene codes for part of the bitter taste receptor in tongue cells. One of its five alleles (forms) causes a . lack of ability to sense bitter tastes; the other four alleles produce intermediate to fully sensitive taste

The inheritance of chromosomes—Meiosis 1. The 23 pairs of chromosomes in the cell are duplicated every time a cell division occurs. 2. The only exceptions to this rule are gametes (ovum and sperm), which are produced by sex organ. 3. Gametes are produced by a special cell division called Meiosis. 4.

Studied inheritance of traits in pea plants. Dominant – the trait that hides the recessive trait (symbolized with a capitalized letter) Recessive – the trait that is hidden (symbolized with a lowercase letter) Alleles – alternate forms of a gene. Homozygous – two of the same allele for a trait (RR or rr)
