The correct answer for this question is this one: "
Mendel shows that dominant alleles always took over, while sometimes in the F2 generation recessive traits would come back. As you can see, f<span>rom the proportions of phenotypes in the offspring. Then, if given that the genes would be equal you would get 1/4 A, 1/4 B and 1/2 AB; but you often get 1/4 A and 3/4 B.</span>
Answer: fewer areas have fertile soil reducing crop production
Explanation:
I j got it right
Last one - Biodiversity is the diversity of species in an area, which makes an ecosystem better prepared for major changes
Explanation:
If one crop struggles to grow then there will be plenty of others to substitute it. If a prey animal is dying at a faster rate and harder to find, predators can have other prey options and so forth. Biodiversity makes it so ecosystems can get past change.
Answer:
a. the environmental variance (VE) = 3.5 g ²
b. 17.5 g ² for population
c. the heritability of broad sense (H2) = 0.83
Explanation:
a.With the information we have we can infer that environmental factors influence A, which is considered isogenic, thus, the environmental variance (VE) = 3.5 g ²
b.When studying population B, comparing it without environmental changes with respect to population A, we found that its total variance (VT) = 21.0g ²
We generate the following formula with the data obtained previously to find the genetic variation
VT = VE + VG
then VG = VT-VE
replacing data:
VG = 21.0 - 3.5 = 17.5 g ² for population
c. Regarding the heritability of broad sense (H2) in population B, we can reach the result with the data previously obtained like this:
H2 = VG / VT = 17.5 / 21.0 = 0.83
