If YOU are human, then YOUR cells have 46 chromosomes and your parents’ cells each have 46 chromosomes. Agreed?

Data are from all models from CASP2 andCASP3 (Critical Assessment of Techniques for Protein Structure�) for which 80% of the protein residues are modeled. Eachtarget This fusion of gametes is called fertilisation. . Sexual reproduction allows some of the genetic information from each parent to mix, producing offspring that resemble their parents, but are not identical to them. In this way, sexual reproduction leads to variety in the offspring. Animals and plants can reproduce using sexual reproduction..
