PPT-Sexual reproduction happens when a male gamete and a female gamete join. 

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. - Recognized as a deviation from predictions offered by a strict selection model. . In this case, there are different selective pressures on each SEX..

If YOU are human, then YOUR cells have 46 chromosomes and your parents’ cells each have 46 chromosomes. Agreed? If you get DNA from both your parents then why wouldn’t you end up with 92 chromosomes? . Unit 2: Organisms and Evolution. Advanced Higher Biology. Miss A Aitken. Costs and Benefits. Two forms of reproduction:. Sexual Reproduction. Asexual Reproduction. Why do both forms exist?. They must exist because neither one is perfect for all situations. If it was perfect, only one would exist.. Recall that sexual reproduction occurs when one haploid . –. the . sperm. . –. fuses together with. another haploid – the . egg. . . Each haploid contains . 23. chromosomes.. When they combine they produce a .
