Genrish500 [490]

The question is incomplete. Here is the complete question.

You are studying a population of ground squirrels. You trap 100 individuals and find 9 that have a light colored coat and the rest have a dark coat. You know that light coat color is recessive in ground squirrels. What is the allele frequency for the light coat allele  and the dark coat allele? How many of the dark coated individuals do you expect to be heterozygotes at the coat color gene? Assume the population is at H-W equilibrium.

Answer: Allele frequency for light coat: q = 0.3;

              Allele frequency for dark coat: p = 0.7;

             There will be 42 heterozygote;

Explanation: A population in H-W equilibrium is a population which doesn't change from one generation to the next if there are no disturbing factors, as migration or mutation.

It follows the equation: p^{2}+2pq+q^{2}=1.

p represents the frequency of the dominant allele;

q represents the frequency of the recessive allele;

2pq represents heterozygote individuals;

The sum of frequencies of both alleles must be 1, i.e.: p+q=1

For the population of squirrels:

  • Frequency of recessive allele

q^{2} = \frac{9}{100}

q = \sqrt{\frac{9}{100}}

q = 0.3

  • Frequency of dominant allele

p+q=1

p=1-q

p=1-0.3

p = 0.7

  • Frequency of heterozygote

2pq = 2*0.7*0.3 = 0.42

In a population of 100 individuals: 0.42*100 = 42

The allele frequency for the light coat is 0.3; for the dark coat is 0.7.

It is expected to have 42 heterozygote individuals in this population.

This biome contains plants that are adapted to prevent water loss due to the low average rainfall and high temperatures year-rou
sladkih [1.3K]

Answer:

This is a Desert Biome.

Explanation:

  • There are hot deserts and cold desert.
  • Here the question is stating about the hot deserts.
  • Hot deserts are characterized by extremely hot and arid climate.
  • Average annual range of rainfall is as low as 25 cm.
  • Deserts lack vegetation except at some patches.
  • Plants that survive in hot deserts have several adaptation to check the loss of water through transpiration.
  • These adaptation include, succulent stems, cuticularized epidermis, Reduction of leaves into spines or thorns, stems modified into phylloclades and deep roots to absorb water.

What is a good example of a response-based definition of stress?
TEA [102]

Answer:

What is a good example of a response-based definition of stress?

Bruce experiences stress because his heart rate increased when he noticed Jack had a knife.

Explanation:

Stress can have many different causes. In this case, it is produced by seeing danger in Jack by having a knife. His heart rate increases because this is a common response in stress, which would enable people to scape. It is important to control stress lebels.

A stressor is distinguished as a threat. If someone anticipates that it could lead to some kind of harm, loss, or other negative consequence. However, if you see the positive side and believe that it carries the potential for gain or personal growth, it would be appraised as a Challenge.
