1141 Germinal epithelium cells spermatogonium Sertoli cell Developing spermatozoa spermatids Leydig cell Each time a spermatogonium divides it may either undergo mitosis to maintain the number of spermatogonia or spermatogenesis. What is asexual reproduction. ?. Asexual reproduction. is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only, it is reproduction which does not involve . Animal Science. What is Reproduction? . It occurs when organisms multiply, or produce offspring.. Sexual reproduction occurs when a female gamete and a male gamete unite..

Organisms and Evolution. SQA mandatory key information. Disadvantages of sexual reproduction – males unable to produce offspring, only half of each parent’s genome passed onto offspring. Benefits outweigh disadvantages due to increase in genetic variation in the population. . Asexual Reproduction. only one parent is involved.. 100% of the genetic material from the one parent is passed on.. Bacteria . primarily reproduce asexually.. Examples of Asexual Reproduction. Binary fission . Life Cycle. Life Cycle. – the development of an organism from fertilization to birth, growth, reproduction, and death.. The life cycle of every organism has these 4 main stages. 1. .

How do seed plants reproduce?. How can you identify fruits?. ACTIVITY. 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. In asexual reproduction, one individual produces offspring that are genetically identical to itself. These offspring are produced by mitosis. There are many invertebrates, including sea stars and sea anemones for example, that produce by asexual reproduction..
