Answer:

The correct answer is sedimentary rock.

Explanation:

The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.

Consider a wildflower population with the following allele and genotype frequencies. Frequency of the CR allele: p = 0.6 Frequen
k0ka [10]

NO,  It Isn't

Ideally a population in Hardy Weinberg equilibrium should hold true to the following equation for genotypic frequencies of an allele;

P² + 2pq + q² = 1

Explanation:

We are provided with allelic frequencies hence we can derive the genotypic frequencies; (CR allele: p = 0.6 Frequency of the CW allele: q = 0.4)

P² = 0.6 ^2 = 0.36

2pq = 2 * 0.6 * 0.4 = 0.48

q² = 0.4 ^ 2 = 0.16

Lets find out if all add up to  as supposed to;

0.36 +  0.48 + 0.16 = 1

Converting to percentages is easy – just multiply by 100

  • 36 % CRCR
  • 48% CRCW
  • and 16 % CWCW

The population provided is not in equilibrium because their percentages vary widely to that the expected Hardy Weinberg's equilibrium percentages. This could be attributed to factors like;

  1. Migration
  2. Mutations,
  3. There is natural selection in progress in the population
  4. There is gene flow
