Answer:
d
Step-by-step explanation:
Hardy Weinberg equilibrium equation is represented below
p² + 2pq + q²
p = 0.6 and q = 0.4
with p² representing homozygous dominant frequency and q² representing homozygous recessive frequency
the expected frequency is of heterozygotes = 2pq = 2 × 0.60 × 0.40 = 0.48
