A.The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals.
FF genotype frequency:
98÷200=0,49. There are approximately 5 <span>homozygous dominant mice in 10.
Ff genotype frequency:
84</span>÷200=0,42. There are approximately 4 <span>heterozygous mice in 10.
ff genotype frequency:
18</span>÷200=0,09. There are approximately 1 <span>homozygous recessive mouse in 10.
B.To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
</span>

<span>=0.7
There are 7 F alleles in 10 random alleles.
f </span>allele frequency:

=0.3
There are 3 f alleles in 10 random alleles.<span>

Gene mutations can be passed on to future generations and drive natural selection. ... Gene mutations can be helpful, harmful, or neutral for an organism's survival. Only mutations that are helpful in the organism's environment would influence its survival and reproduction
<span>Cohesion- attraction of molecules of the same substanceCauses water molecules to be drawn together to form a smooth surface (surface tension)adhesion- attraction of molecules to different substances<span>The correct answer is A because the cohesion causes water to form in drops, and adhesion allows it to stick to different substances, such as the pine needles</span></span>
