Answer:
0.5
Explanation:
According to Hardy-Weinberg equilibrium p2+2pq+q2=1 (p+q=1)
p2 is frequency of the dominant homozygous genotype
2pq is the frequency of the heterozygous genotype
q2 is the frequency of the recessive homozygous genotype
In the example above 80 chickens have bare legs (ff)-recessive homozygous which means that the frequency of that genotype is 80/240+80=0.25 (q2), frequency of the recessive allele is
=0.5. This means that the frequency of the dominant allele (p) is 1-0.5=0.5
So, the frequency of the heterozygous genotype (2pq) is 2*0.5*0.5=0.5
The frequency of the dominant homozygous genotype is p2=0.25
Answer:
An index fossil is a fossil used to determine the age of the sediments in which it is found. When quickly approximating the age of new finds, an archaeologist looks at the rocks in which it is buried, as those sediments would have been on the surface at the time of the death of the pre-historic creature.

The amount of ozone and particle concentrations in a given area are influenced by a variety of weather-related factors, therefore the weather can have a significant impact on air quality.
<h3>What influences the air's quality?</h3>
The quality of the air is influenced by a variety of climate-related elements, including temperatures, cloud cover, humidity, precipitation frequency and intensity, wind patterns, and others.
In India, more than 90% of people live in areas where the air quality is below WHO limits. The biggest sources of pollution are factories, coal-fired power plants, and automobiles.

Small intestine
Peyer's patch are small masses of lymphatic tissue found usually in the ileum region of the small intestine. This is an aggregated lymphoid nodules and form an important function in immune system. This allows to monitor bacterial population and prevents the growth of pathogenic flora in the intestine. They are egg shaped lymphatic tissue that are similar to lymph nodes in structure except the absence of connective tissue.
