Genetic Diversity And Natural Selection

Question 1

What is genetic diversity?

Answer 1

The number of different alleles of genes in a population

Question 2

What is natural selection?

Answer 2

The process that leads to evolution in populations

Question 3

What is evolution?

Answer 3

The change in allele frequency over many generations in a population and results in species becoming better adapted to their environment

Question 4

Describe the process of natural selection.

Answer 4

1. New alleles for a gene are created by random mutations
2. If this new allele increases the chances of that individual surviving in that environment it is more likely to survive and reproduce
3. This reproduction passed down the advantageous gene onto the next generation
4. Over many generations the new allele increases in frequency in a population
