Mendelian inheritance specifies that if two heterozygous individuals mate, the chances that a child would be homozygous for the recessive allele would be 25%.
Certain patterns of how qualities are passed from parents to children are referred to as mendelian inheritance. Gregor Mendel, an Austrian monk who conducted countless pea plant tests in the 19th century, developed these broad patterns. A chart known as a Punnett square makes it simple to ascertain the predicted ratios of potential genotypes in the offspring of two parents. The hypothetical situation shown in Figure below.
The gene in question is autosomal, and both parents have heterozygotes for it (Aa). Each parent will generate half the gametes with the A allele and half the gametes with the an allele. The potential genotypes of their offspring are revealed by filling in the Punnett square's cells.
It displays the potential genotype ratios that are most likely to occur, in this case 25% AA, 50% Aa, and 25% aa.
