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
the phospholipids are tightly packed togther and the membrane has a hydrophobic interior.
Chemical (mutagens)
usually either mimic the structure of nucleotides and are inserted in DNA or either cause
chemical changes (such as alkylation) in nucleotides hence causing mismatching during replication.
Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an
increased likelihood of mutations during the repair of the DNA by cell
mechanisms.
I think it's prophase, antaphase, metaphase, and telophase.
