Given an inheritance pattern of incomplete dominance and 81 flowers that are red (R¹^R¹),18 flowers that are pink (R¹^R²),and 1 flower that is white (R²^R²),the frequency of the R¹ allele is 0.9.

Question

Quizplus · Accepted Answer

We can use the Hardy-Weinberg equation to calculate the frequency of the R¹ allele:

p² + 2pq + q² = 1

where p is the frequency of the R¹ allele, and q is the frequency of the R² allele.

We are given that there are 81 red flowers and 18 pink flowers, which together make up 99 flowers that carry the R¹ allele:

2pq = number of heterozygous individuals = 18
p + q = 1 (since there are only two alleles)

Solving these equations simultaneously gives:

p = frequency of R¹ allele = 0.9
q = frequency of R² allele = 0.1

Therefore, the statement is true.
