You discover a population of mustard plants and find it to be at Hardy–Weinberg equilibrium with respect to the R locus. Suppose
natulia [17]

Answer:

The fraction of heterozygous individuals in the population is 32/100 that equals 0.32 which is the genotipic proportion for these endividuals.

Explanation:

According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the alleles. The genotypic frequencies after one generation are p² (Homozygous for allele p), 2pq (Heterozygous), q² (Homozygous for the allele q). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.

In the exposed example, the r-6 allelic frequency is 0,2. This means that if r-6=0.2, then the other allele frequency (R) is=0.8, and the sum of both the allelic frequencies equals one. This is:

p + q = 1

r-6 + R = 1  

0.2 + 0.8 = 1

Then, the genotypic proportion for the homozygous individuals RR is 0.8 ² = 0.64

The genotypic proportion for the homozygous individuals r-6r-6 is 0.2² = 0.04

And the genotypic proportion for heterozygous individuals Rr-6 is 2xRxr-6 = 2 x 0.8 x 0.2 = 0.32

The world's average footprint per person is about 2.7 hectares per person. At that size, we are depleting our renewable resource
MariettaO [177]
<h2>Answer is "3.5 times"</h2>

Explanation:

  • A measure of how a lot of region of naturally productive land and water an individual, population or action requires to create all the assets it consumes and to absorb the waste it produces, utilizing winning innovation and asset the board rehearses. The Ecological Footprint is normally estimated in worldwide hectares.
  • Since the exchange is worldwide, an individual or nation's Footprint incorporates land or ocean from everywhere throughout the world. Moving along without any more particular, Ecological Footprint, for the most part, alludes to the Ecological Footprint of utilization.
  • Natural Footprint is frequently alluded to in a short structure as Footprint. "Biological Footprint" and "Impression" are formal people, places or things and along these lines ought to consistently be capitalized.
  • Hence, the right answer is "3.5 times larger than the average world footprint"
