First and last is the answer
Answer:
Explanation:
C = dominant black coat
c = recessive white coat
T = dominant rough coat
t = recessive smooth coat
Heterozygous black coat + Homozygous smooth guinea pig genotype:
Cc tt
homozygous white/heterozygous rough:
cc Tt
Punnett Square
After looking at Punnett squares attached, we can see that 1/2 of offspring are either black or white and 1/2 of offspring are either rough or smooth.
Cc - black coat - 2/4 - 1/2
cc - white coat - 2/4 - 1/2
Tt - rough coat - 2/4 - 1/2
tt - smooth coat - 2/4 - 1/2
The soleus muscle is mainly used for pushing off the ground while walking. It is important for activities such as walking and running. This muscle also helps in maintaining a person’s posture by preventing the person from falling forward. Thus, this muscle is more often used by marathon runners.
"Directional selection" will most likely occur.
<u>Answer:</u> Option B
<u>Explanation:</u>
Directional selection or positive selection is an organic selection mechanism in population genetics, this scrutiny is an intense phenotype is preferred over certain phenotypes, allowing the intensity of the allele to migrate over moment towards that phenotype.
For an instance directional selection are fossil statistics showing that the scale of black bears in Europe diminished throughout ice ages interglacial phases however grew at each glacial period. A further example is the scale of the beak in a finch group.
