In sexually reproducing organisms, each offspring has two copies of each gene because they inherit genetic material from both parents. This inheritance of genes is a result of the union of two haploid gametes, with each gamete supplying one set of genes. In humans, for example, the sperm from the father and the egg from the mother each contain 23 chromosomes. When the sperm and egg combine during fertilization, the resulting embryo has 46 chromosomes: 23 inherited from the father and 23 from the mother. In terms of genes, this means that the offspring have two alleles for each gene, with one allele coming from each parent, thus forming the organism's genotype. This genetic constitution subsequently determines the organism's phenotype, or physical appearance.

Offspring of sexually reproducing organisms inherit two copies of each gene, one from each parent, during fertilization when haploid gametes combine. This process allows for genetic variation since each parent contributes different alleles. The resulting diploid organism has a unique genetic profile based on the combination of genes from both parents.
