Desert and tundra both ________.

Biology
1 answer:
NARA [144]3 years ago
3 0

Answer: Option A. Have relatively low participation

Explanation: Dessert and tundra have a relative low precipitation. Desert is a very dry place and they have varying temperature. Many factors causes the low precipitation of desert, such as pressure. Atmospheric pressure contributes to low precipitation. Lack of available surface water on the soil for evaporation also affects desert precipitation.

There is low precipitation in the tundra as a result of extreme cold temperatures of the tundra. There is so much frozen on the ground and the air is very cold, all this causes low precipitation of tundra.

svetlana [45]

Answer:

The options

a. New combinations of genes yielding genotypes of greater fitness

b. Few heterozygotes because of underdominance

c. Frequency-dependent selection, leading to fluctuations in fitness

d. Heterozygotes with greater fitness, owing to overdominance

e. A random assortment of genotypes because of genetic drift

The CORRECT ANSWER IS b.

b. Few heterozygotes because of under dominance

Explanation:

In genetics, underdominance (at times called "negative overdominance") is the opposite of overdominance.

It is the selection against the heterozygote, that leads to disruptive selection and divergent genotypes. It occurs in cases of inferior and reduced fitness (As in our case study, it is the different chromosomal fusions and inversions)

of the heterozygotic genotype to the dominant or recessive homozygotic genotype. It is unstable as it causes fixation of either allele.

Another example is the African butterfly species Pseudacraea eurytus, which makes use of Batesian mimicry to avoid predation. This species carries two alleles that gives a coloration that is alike to a different local butterfly species that is harmful to its predator. The butterflies who are heterozygous for this trait are observed to be intermediate in coloration and thus encounter an higher risk of predation and a decrease in the total fitness.
