Inheritance is the process by

Inheritance is the process by which characters are passed from parent to progeny. Variation refers to differences between progeny and parents. Genetic

Gregor Mendel carried out hybridisation experiments

Gregor Mendel carried out hybridisation experiments on garden peas for seven years and selected 14 true-breeding varieties with contrasting traits. Hi

In a dissimilar pair of factors

In a dissimilar pair of factors, one member dominates the other. In a monohybrid cross for height, T is dominant over t, so all F1 plants are tall eve

The two alleles of a gene

The two alleles of a gene separate during gamete formation, so each gamete receives only one allele. In the F2 generation, the hidden recessive trait

A cross involving one character

A cross involving one character, such as tall and dwarf pea plants, gives F1 tall plants and an F2 phenotypic ratio of 3:1. The genotypic ratio in F2
