Reproduction and Heredity Standard # 8: Recognize that hereditary information is contained in genes located in the chromosomes of each cell. A human cell contains about 30,000 different genes on 23 different chromosomes. Standard #9: Compare sexual reproduction (offspring inherit half of their genes from each parent) with asexual reproduction (offspring is an identical copy of the parent’s cell).
Major Learning Targets:
I can explain the difference between sexual and asexual reproduction
I can name and describe methods of asexual reproduction
I can explain how a cell divides and copies its genetic information
I can illustrate the difference between mitosis and meiosis
Important Concepts:
In asexual reproduction the offspring is identical to the parent
Meiosis produces the gametes for sexual reproduction
Two sex cells must join in sexual reproduction to create the genetic code for a new organism, each sex cell only contains half the necessary DNA for the organism
There are both male and female cells needed for sexual reproduction
Understand how gametes are different from regular cells
Know that sexual reproduction results in greater variety in the offspring than asexual reproduction because it incorporates genes for two organism
