Understanding Spermatogenesis and oogenesis both involve mitosis cell growth two divisions of meiosis and differentiation Processes in spermatogenesis and oogenesis result in different numbers of gametes with different amounts of cytoplasm.

Sexual vs. Asexual Reproduction Compare the results of uniform or diverse offspring from sexual or asexual reproduction Uniform offspring Diverse offspring Sexual reproduction Asexual reproduction Sexual Reproduction 1. Asexual Reproduction. Requires only one parent. Offspring have 100% the same chromosomes as the parent.. In other words, the offspring are exact “clones” of the parent.. 2. Asexual Reproduction.

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.. 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.. 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 .
