Answer: A
Explanation: I did the test
The answer is C. Genetic drift is the change of an allelic frequency due to random sampling in a population. When the brown and black bottles are preyed upon compared to the green bettles, their numbers in a population decrease. Therefore the next generations/offsprings of bettles population is more likely to be of green beetles since they will be more in the parent population. The allelic frequency of the allele for green bettles becomes higher than that of brown and black beetles. Eventually, after generations, the black and brown beetles may be eliminated from the population
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from <em>homzygous.</em>
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous <em>dominant</em>, which means there will be two of the same dominant alleles, so, RR.
