PPT-3.2 Sexual Reproduction & the Diversity of Life

32 Sexual Reproduction amp the Diversity of Life Joining or fusing two gametes is called fertilization This will create a Zygote first diploid 46 chromosomes cell of the offspring. The . disadvantages and advantages of sexual . reproduction. CfE. . Advanced Higher Biology. Unit . 2: . 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. . 1. Make a Venn Diagram. 2. Asexual Reproduction. Sexual Reproduction. Both. Types of reproduction in living organisms. Asexual Reproduction. Requires only one parent. Offspring have 100% the same chromosomes as the parent.. 1. Make a Venn Diagram. 2. Asexual Reproduction. Sexual Reproduction. Both. Types of reproduction in living organisms. Pass DNA from parent to offspring. Asexual Reproduction. Requires only one parent. How do species become varied?. Do animals and plants reproduce the same ways?. Are there other ways that a species can be varied?. Asexual and Sexual Reproduction. Reproduction produces new individual species. The way a species reproduces determines how much variation the new individual will have. . reproduction: . The . disadvantages and advantages of sexual . reproduction. CfE. . Advanced Higher Biology.

This means that it . only requires 1 organism . (ex. Skin cells dividing). For growth and repair in . somatic. (body) cells!. Results in 2 cells identical to the original (parent) cell. 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. Test Tomorrow!!!!!!!. Which of the following is an advantage of sexual reproduction over asexual reproduction?. I. Sexual reproduction is more rapid and less complicated.. II. Sexual reproduction results in more diversity.. © Copyright 2015 – all rights reserved . www.cpalms.org. How do Sexual and Asexual Reproduction compare?. DNA transfer through . sexual. reproduction (meiosis) and . asexual. reproduction (mitosis) equip organisms in different ways for survival. Phylum. Class. Order. Family. Genus. Species. Archaea. - Single celled prokaryotes that reproduce asexually. 4 major phyla. Extremophyles. Have cell walls with no peptidoglycan. Diverse metabolic pathways. 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.. 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 . Class:I. . B.Sc.,Microbiology. By. . A.Swedha. Assistant Professor. Department of Microbiology. Jamal Mohamed College(Autonomous). . Trichy.
