<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
DNA helicases "unzip" the DNA molecule in preparation for replication; they break the hydrogen bonds between the two annealed nucleotide bases.
Answer:
f(A1) = 0.9700, f(A2) = 0.0300
Explanation:
The frequency of homozygous recessive genotype of children is
As per Hardy weinberg's equation, frequency of homozygous recessive genotype is represented by
Here
Thus, frequency of recessive allele would be
as per first law of Hardy weinberg
Hence, option C is correct
Answer:
Yes. they are living and living in the backyard so therefore they are considered part of the population of the backyard. You can also include any birds, squirrels, and any other animals that you see.
