Answer:
L allele: 0.575 (or 57.5%)
l allele: 0.425 (or 42.5 %)
Explanation:
Homo-zygous individuals have two copies of the same allele (i.e., either L alelle or l allele), while heterozygous individuals carry both alleles at a time (i.e., one L allele and one l allele). In consequence:
- Frequency of the L allele: [(450 x 2) + 250] / 2000 = 0.575
- Frequency of the l allele: [(300 x 2) + 250] / 2000 = 0.425
Extinction happens when there is a major climate change, then some species are unable to adapt to those changes, so they become extinct. Extinction basically occurs when species are unable to adapt quickly enough to the environment
