In humans, MN blood types are determined by an autosomal gene with two alleles: LM and LN. In one population of 592 people, ther
RoseWind [281]

Answer:

148

Explanation:

According to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1 where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

Here,

Total population = 592

Number of NN people = 148

Frequency of N blood group or NN genotype (q²) = 148/592 = 0.25

q = √0.25 = 0.5

p = 1 - q

= 1 - 0.5 = 0.5

Hence, p = 0.5

Frequency of MM genotype = p² = 0.25

Number of people with MM genotype = 0.25*592 = 148

Hence, 148 people will have MM genotype or M blood group.

7. Phytochrome prevents seeds of some plants from germinating when they are in deep shade by the: absorption of far-red waveleng
SIZIF [17.4K]
<h2>Function of Phytochrome </h2>

Explanation:

  • The <em>color of light</em> that they absorb maximally by the two types such as   <em>Pfr is a blue-green structure</em> that ingests far-<em>red light (730 nm)</em> and<em> Pr is a blue structure that retains red light (660 nm)</em>
  • <em>Pfr assimilates far-red light</em>, it is changed over to the <em>Pr structure</em>
  • Pfr can spontaneously revert to the Pr form  structure in obscurity <em>dark over time = dark reversion Pfr</em> is additionally helpless to proteinases
  • <em>Pfr contains  some red light, so in red light 15% Pr and   there is a parity of 85% Pfr.</em>
  • <em>The  phytochrome (Pr)</em> is changed over to the organically dynamic structure red light with the <em>Pfr under illumination</em>
  • <em>Darkness and Far -red light convert</em> the particle back to the inactive form.
