PPT-Asexual reproduction – 1

Asexual reproduction Overview Example 1 Garlic Allium sativum As far as we know garlic in cultivation throughout history has only been propagated asexually by way of vegetative cloves bulbs and bulbils or topsets not from seed These asexually propagated genetically distinct selections of garlic we cultivate are more generally called clones Yet this asexual lifestyle of cultivated garlic forgoes the possibility of combining traits proffered by interpollinating diverse parental stocks. Biology 4.1. Asexual Reproduction. Asexual reproduction results in the production of a new organism . The organism produced has . ____________. to . the parent . Asexual Reproduction can be found in . Asexual reproduction . Asexual reproduction is reproduction without . sex, by which an organism reproduces through . MITOSIS. . . Mitosis is a form of cell replication that makes . EXACT. copies of the parent cell. . 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. . Reminder:. Mitosis. Meiosis. Forms sex cells (sperm and eggs). ½ the number of chromosomes compared to the parent cell. Genetically identical to parent cell. Responsible for growth, differentiation, and asexual reproduction. Reminder:. Mitosis. Meiosis. Forms sex cells (sperm and eggs). ½ the number of chromosomes compared to the parent cell. Genetically identical to parent cell. Responsible for growth, differentiation, and asexual reproduction. 06 Many organisms reproduce by asexual means. 06.1 Understand that, in eukaryotes, asexual reproduction involves mitosis. Survival of a species involves reproduction. Two methods: sexual and asexual. reproduction: . 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. . Lesson 3: Plant Reproduction. Essential Questions. What is the alternation of generations in plants?. How do seedless plants reproduce?. How do seed plants reproduce?. How can you identify fruits?. ACTIVITY. 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. Punnett. Square. In Roses having thorns is dominant to not having thorns. Use the . punnett. square to predict the probability that the offspring produced between two heterozygous roses will have thorns. . A . clone. is an identical genetic copy of its parent. Many organisms naturally form clones via asexual reproduction. Cloning is also used in agriculture and research to copy desired organisms, tissues and genes. To be able to explain Sexual Reproduction. To be able to give advantages and disadvantages for each. R. eproduction. Why does reproduction exist?. What is reproduction?. . Sexual. reproduction involves . 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.. Sexual reproduction and meiosis. Sexual reproduction. : requires two sex cells to combine during fertilization.. Egg:. female sex cell. Sperm:. . male sex cell. Fertilization. : the joining of egg and sperm.
