Need more information to complete the question. what’s the data? what are you recording? what’s the experiment?
Answer:
0.549 is the frequency of the F allele.
0.495 is the frequency of the Ff genotype.
Explanation:
<em>FF </em>or <em>Ff</em> genotypes determine freckles, <em>ff</em> determines lack of freckels.
In this class of 123 students, 98 have freckles (and 123-98= 25 do not).
If the class is in Hardy-Weinberg equilibrium for this trait, then the genotypic frequency of the ff genotype is:
q²= 25/123
q²=0.203
q= 
q= 0.451
<em>q </em>is the frequency of the recessive f allele.
Given <em>p</em> the frequency of the dominant F allele, we know that:
p+q=1, therefore p=1-q
p=0.549 is the frequency of the F allele.
The frequency of the Ff genotype is 2pq. Therefore:
2pq=2×0.549×0.451
2pq=0.495 is the frequency of the Ff genotype.
Answer:
A population comprises individuals of the same species. A community however is comprised of different populations of several species coexisting in the same area. In short, a population only refers to one species, but a community refers to all living species within a certain area.
Answer:
Forests are helpful, They provide clean oxygen for us. Imagine life without forests. Now that wouldn't be good for the animals would it? Many animals are very important to the earth. Forests nurture the soil, Forests absorb carbon, Forests provide food for millions, Forests are natural aqueducts, Forests host 80% of Earth's biodiversity. There are many reasons why we need forests. Overview, Forests are vital to life on Earth. They purify the air we breathe, filter the water we drink, prevent erosion, and act as an important buffer against climate change.
Answer:
A. Interphase
Explanation:
Interphase is when the DNA is copying itself. It is being prepared for the cell to divide and one of the key parts of mitosis is when the chromosomes duplicate, so to prepare for mitosis, the chromosomes must duplicate during interphase.
