Both parents must contribute a copy of the same gene. This implies that each pea plant possesses two sets of all genes, with one set inherited from each parent.

Both parents must contribute a copy of the same gene. This implies that each pea plant possesses two sets of all genes, with one set inherited from each parent.
For both parents to help determine a trait in the progeny, the trait must be influenced by genes contributed by each parent. The trait should be controlled by alleles located on homologous chromosomes, one inherited from the mother and the other from the father. The specific combination of alleles inherited from both parents determines the genotype of the offspring, influencing the observed phenotype or trait. This principle aligns with Mendel’s laws of inheritance, where traits are often governed by pairs of alleles, and both parents contribute to the genetic composition of their progeny, influencing the expression of specific traits.
