Question

For a population at Hardy–Weinberg equilibrium in regard to a two-allelic gene (e.g. gene A with two alleles A+ and A–, the frequency of A–A– homozygotes will be the greatest when ____. Group of answer choices A+ > A– A+ < A– A+ = A– A+ >> A– A+ << A– The allelic frequencies and the genotypic distribution of these alleles will remain constant. The allelic frequencies will not change over time, but the genotypic distribution of these alleles will change (e.g. more heterozygotes, fewer homozygotes, etc). The allelic frequencies and the genotypic distribution of these alleles will change over time (e.g. more heterozygotes, fewer homozygotes, etc).

00:01 Hi, so there's a discussion about hardiv -enburg equilibrium and we have to fill certain blanks related to it.

00:07 So first one is the condition of hard -ewenberg equilibrium.

00:11 So it is random meeting.

00:13 So random meeting is the condition for hard -evenberg equilibrium.

00:18 Now next blank it says, the dash not affected by allele.

00:22 So what will not be affected by allele? so in hard -evenberg equilibrium, genotype is not affected by allele.

00:30 Now third one, it is same, which is allelic and genotypic frequencies.

00:36 So same.

00:38 So what remains same in hardinberg principle? it is ellic and genotypic frequencies.

00:47 Allelic and genotypic frequencies, which remains the same.

00:53 Frequencies, which remains the same.

00:58 Now next blank is genotypic.

01:00 Genotypic frequency is fully determined by allelic frequencies.

01:05 So this fourth point will be genotypic, genotypic frequency, genotypic frequency fully determined by allelic frequencies, determined by allelic frequency.

01:30 Then next it comes the fifth blank.

01:34 It is conditions of hardi -bin -bug equilibrium.

01:39 So next blank will be equilibrium.

01:43 So it is the conditions of hardi -win -bug equilibrium which are sometimes not strictly met in practice.

01:51 Not strictly met in practice.

01:56 Now after this, the sixth blank, it is the gene.

02:05 Now the seventh answer is selection among individuals...
