The earth is the third planet from the centre of our Solar System, orbiting the Sun. The Moon is a natural satellite of the Earth, orbiting it in a circular orbit. The moon is in eastern quadrature at first quarter. On the sky's dome, the sun is 90º east. A last quarter moon, on the other hand, is the same as a moon in western quadrature, when the moon is 90 ° west of the sun.

Answer:

The First Quarter Moon is a primary Moon phase when half of the Moon's face is lit up. Whether it is the left or right half depends on where you are on Earth.

Recall that in Mendel's garden peas, the yellow gene determines flower color, with the A (yellow) allele dominant to the a (gree

Rufina [12.5K]

Answer:

Frequency of allele "A" $= 0.7071$

Frequency of allele "a" $= 0.2929$

Explanation:

Given,

The alleles for flower color are A (yellow) and a (green) where A is dominant to a.

The genotype frequencies are -

AA - $p^{2} = 50$ %

Aa - $pq= 25$ %

aa- $q^{2} = 25$ %

so the frequency of allele A is equal to $p$

$p = \sqrt{p^2} \\p = \sqrt{0.5} \\p = 0.7071$

As per Hardy Weinberg's equation 1-

$p+q=1\\$

Substituting the value of "p" in above equation, we get -

$q=1-0.7071\\q=0.2929$

So the Frequency of allele "A" $= 0.7071$

Frequency of allele "a" $= 0.2929$
