C. Decreased death rate is the answer
Answer: The frequency of brown beetles is 0.32.
Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:
1 - 0.8 = 0.2
In Hardy-Weinberg principle,

2pq represents the frequency of heterozygote individuals, so:
genotype A1A2 = 2*0.8*0.2 = 0.32.
Thus, the frequency of brown beetles (A1A2) in the population is 0.32.
They could look for similarities in the DNA or protein structuresof the organisms<span> and similarities in early development</span>
Hi. excuse me sorry but i cant see your question. do you think you could post it again, please?
thank you
