<h2>Ovulation </h2>

Explanation:

In women, luteinizing hormone carries out different roles in the two halves of the menstrual cycle

In week one to two of the cycle, luteinizing hormone is required to stimulate the ovarian follicles in the ovary to produce the female sex hormone, oestradiol
Around day 14 of the cycle, a surge in luteinizing hormone levels causes the ovarian follicle to tear and release a mature oocyte (egg) from the ovary, a process called ovulation
For the remainder of the cycle (weeks three to four), the remnants of the ovarian follicle forms a corpus luteum
Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs

ivann1987 [24]

Answer:

Frequency of heterozygous animals with agouti fur is $42$ %

Explanation:

As per the Hardy Weinberg's equation -

$q^2$ represents the frequency of population with phenotype expressed by homozygous recessive genotype

$p^ 2$ represents the frequency of population with phenotype expressed by homozygous dominant genotype

and $2pq$ represents the frequency of population with phenotype expressed by homozygous recessive genotype

Given -

$q^2 = 0.49\\q = 0.7$

As per first principle of Hardy Weinberg's equilibrium

$p + q = 1$

Substituting the value of q in above equation, we get -

$p = 1- 0.7 \\p = 0.3$

As per second principle of Hardy Weinberg's equilibrium

$p^2 + q^2 + 2pq = 1\\$

Substituting the given values in above equation, we get -

$0.09 + 0.49 + 2pq = 1\\2pq = 1 - 0.58 \\2pq = 0.42$

Frequency of heterozygous animals with agouti fur is $42$ %
