Read about the Hardy-Weinberg Equation and work through the Hardy-Weinberg example in Procedure 11.6. Then solve the equation for the following example: In a population of 400 pea plants, 64 of them produce the recessive white flowers while the others produce the dominant purple flowers. Use the Hardy-Weinberg equation to calculate the proportion of the population that is homozygous dominant, heterozygous, and homozygous recessive: 42 = 0.1 * P^2 + 2 * p * q + 0.9 * q^2. 0.1 = 1-0.4 = 0.6. Homozygous dominant = 0.4^2 = 0.16. Heterozygous = 2 * 0.4 * 0.6 = 0.48. Homozygous recessive = 0.6^2 = 0.36.

Step 1
First, we need to find the frequency of the recessive allele (q) and the dominant allele (p). Since we know that 64 plants produce white flowers (recessive), we can find the frequency of the homozygous recessive genotype (q^2) by dividing the number of white Show more…

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.

Pea plants produce flowers that have one of two colors: Purple or white. The locus for the gene that produces that pigment in pea plants has two alleles. The P1 allele codes for purple color while the P2 allele codes for white color. Plants that are homozygous for the P1 allele as well as heterozygotes produce purple flowers while homozygotes for the P2 allele produce white flowers. If the frequency of individuals of individuals in a pea plant population that are homozygous for the P1 allele is 0.49 and assuming the population is in Hardy-Weinberg equilibrium, what would be the frequency of: Homozygotes for P2 Heterozygotes
