3.2.4 Apply the Hardy–Weinberg principle to estimate carrier frequency.
Why this video
It walks through step-by-step mathematical examples showing how to determine allele frequencies and calculate the frequency of heterozygous carriers from recessive phenotypes using the Hardy–Weinberg equation.
Part of this line
Covers part of this objective. It leaves out: It does not cover human disease applications, clinical pedigree risk calculations, or the shortcut approximating p as 1 (carrier frequency ≈ 2q). Effort should be spent practicing these clinical applications separately.
Heads up
It calculates the exact value of 2pq rather than using the medical genetics convention of approximating p as 1 to calculate carrier frequency directly as 2q.
