3 0

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

D) Competition favors the fittest organisms. 
This is correct because, in different parts of the world, different organisms need different things to survive, which means if Wolves in Alaska need warm coats to survive, but animals in some parts of America don't, each animal that is the fittest to live in those conditions will survive, while the others with unfavorable genes will not.
