Question

problem 2
in a population of 1,000 flowers, 490 are red, 420 are pink, and 90 are white. red is homozygous dominant (rr), pink is heterozygous (rr), and white is homozygous recessive (rr). use this information to calculate:

• the allele frequencies (p and q)

problem 3
in a population of 2,500 beetles, 100 are homozygous recessive for a wing shape trait. determine:

Explanation:

Step1: Count total alleles

Total flowers = 1000, each has 2 alleles.
Total alleles = $1000 \times 2 = 2000$

Step2: Count R alleles

Red (RR): 490 flowers, each has 2 R alleles. Pink (Rr): 420 flowers, each has 1 R allele.
Number of R alleles = $(490 \times 2) + 420 = 980 + 420 = 1400$

Step3: Calculate p (R frequency)

$p = \frac{\text{Number of R alleles}}{\text{Total alleles}} = \frac{1400}{2000} = 0.7$

Step4: Count r alleles

White (rr): 90 flowers, each has 2 r alleles. Pink (Rr): 420 flowers, each has 1 r allele.
Number of r alleles = $(90 \times 2) + 420 = 180 + 420 = 600$

Step5: Calculate q (r frequency)

$q = \frac{\text{Number of r alleles}}{\text{Total alleles}} = \frac{600}{2000} = 0.3$

Answer:

$p = 0.7$, $q = 0.3$
