social, ethical and economic factors with cloning

Question 9

sources of genetic diversity

Answer 9

-Crossing Over of chromatids in meiosis
-Independent Assortment of chromosomes in meiosis
-Random Mutations
-Random Fusion of -
-Gametes at fertilization
-Gene flow - exchanging of alleles between population

Question 10

natural selection and it’s processes

Question 11

causes of low genetic diversity

Answer 11

-inbreeding
- decrease in population
-monoculture

Question 12

importance of genetic diversity

Answer 12

-Maintains health and stability of a population
> Higher amount of alleles= higher chance at disease resistance

-Improves Biological Fitness (ability to survive and reproduce)

-Increases the Evolutionary Potential through higher genetic diversity

-Low genetic diversity increases risk for extinction (esp. small/fragmented populations)
-Very important in conservation programs for endangered species
