Among a particular population of 100 plants, red flowers are dominant and yellow flowers are recessive. F is the dominant allele and f is the recessive allele. 40 plants are homozygous dominant 44 plants are heterozygous 16 plants are homozygous recessive Use the Hardy-Weinberg equation to calculate the equilibrium frequencies of each genotype.

Transcript

00:01 According to the given information, f is the dominant rate or allele, while small f is the recessive allele.

00:13 So this makes capital f and capital f to be a dominant genotype and small f and small f to be a recessive genotype.

00:28 That way capital f and small f, this genotype will be a heterozygous.

00:36 Dominant.

00:41 Now according to the given information, there are 40 such dominant plants which are having the genotype capital f and capital f.

00:53 16 such plants or offsprings which are having the genotype small f small f so these are recessive ones and the heterocytrus dominant the number is 40.

01:04 So from this we can calculate the total number of plants.

01:10 Thus being observed or thus being studied in this entire experiment is 100.

01:20 Now let us see the hardy weinberg equation that is hw equation to find out the frequencies of each one of these.

01:31 So the hardy weinberg equation is such that p square plus 2pq plus q.

01:39 Square equals to 1.

01:42 So here p square represents the allele frequency for homozygous dominant.

02:00 Not allele frequency but the number of individuals that is homozygous dominant.

02:07 2 pq explains about heterozygous dominant and q square represents the homozygous dominant.

02:22 Cycles recessive...
