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.

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.”. Binary Fission. Bacteria reproduce by a process called binary fission. Binary fission: a copy of their single chromosome is produced and then the cell divides in half so that one half gets one chromosome and the other half gets the other chromosome. 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.. Life. Chapter 5.4 and 5.5. KEY CONCEPT. Many organisms reproduce by cell division.. Asexual reproduction. Creation of offspring from a SINGLE parent that does not involve the joining of gametes.. Binary fission is similar in function to mitosis.. 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..
