Answer: A. Archaea

Domain Archaea is the group of single celled prokaryotic organisms. These organisms lack a well defined nucleus and cell organelles. The cell wall of these organisms lack peptidoglycan which makes them distinct from bacteria. These organisms are tolerant to saline conditions and they survive in marshes, hence they are called as halophiles.  They produce methane as a metabolic byproduct, therefore are called as methanogens.

kirza4 [7]

The statement: Allele frequencies will stay the same, but genotype frequencies will change over time is False, option B

<h3>What are dominant and recessive traits?</h3>

Dominant traits are traits which whenever the allele for such traits appear will always be expressed in the offspring.

Recessive traits are traits which are masked by the dominant trait whenever the allele for the dominant traits appear. Recessive traits are only expressed in the absence of the dominant traits.

In the snail population, the M is dominant over m and that selection acts against hom0zygous recessive individuals.

Also individuals in the population will only mate with others of the same genotype.

Overtime, it will be observed that the allele frequencies and the genotype frequencies will change over time.

In conclusion, the allele frequency and genotype frequencies of the snail population will change over time.

#SPJ1

Note that the complete question is given below:

You are working with a population of snails. during the mating season, you observe that individuals in the population will only mate with others of the same genotype (for example, mm individuals will only mate with mm individuals). there are only two alleles at this locus (M is dominant; m is recessive); you have determined that the frequency of the M allele = 0.4 and that selection acts against h0m0zygous recessive individuals. Consider whatbwill occur in this population overbthe course of many generations and mark A for True or B for False for each of the following statements:

Allele frequencies will stay the same, but genotype frequencies will change over time.
