In a population with two alleles, B and b, the allele frequency of B=0.59. What would be the frequency of the heterozygotes if t
Levart [38]

Answer:

0.483

Explanation:

The given population is in Hardy-Weinberg equilibrium. If the gene has two alleles, the sum total of the frequencies of these two alleles will be one.  

Therefore, the total of the frequency of allele B and frequency of allele b will be 1. f(B) + f(b)=1

If the frequency of allele "B" is 0.59, then the frequency of allele "b" will be=1-0.59= 0.41

The frequency of heterozygous genotype in the population= 2pq

p= frequency of the dominant allele

q= frequency of the recessive allele

So, 2pq= 2 x 0.59 x 0.41 = 0.483

Describe the importance of biomes such as forests, freshwater, and marine biomes? How have human actions affected these biomes?
Allisa [31]

Forest biome:  It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological  functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.

Freshwater biome:  We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.

Marine biome:  It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.

As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
