Detailed explanation-1: -Mendel hypothesized that gametes have only one factor for each inherited trait. This hypothesis is supported by which observation? haploid cells are produced by meiosis. Mendel crossed a true-breeding plant that produced green peas with a true-breeding plant that produced yellow peas to produce an F1 generation.

Detailed explanation-2: -Mendel’s particulate inheritance hypothesis He predicted that the inherited phenotypes don’t blend from generation to generation. Rather, he suggested that the offspring inherit discrete ‘particles. ‘ If one of these particles is dominant, the dominant phenotype will be expressed.

Detailed explanation-3: -Recombination occurs during meiosis and is a process that breaks and recombines pieces of DNA to produce new combinations of genes. Recombination scrambles pieces of maternal and paternal genes, which ensures that genes assort independently from one another.

Detailed explanation-4: -Mendel stated that heritable factors are segregated during gamete formation. More precisely, this law states that a pair of alleles is separated, or segregated, during the formation of gametes. During meiosis, homologous chromosomes are randomly separated.

Detailed explanation-5: -According to the law of segregation, only one of the two gene copies present in an organism is distributed to each gamete (egg or sperm cell) that it makes, and the allocation of the gene copies is random.
