What do the letters inside and outside the punnett square represent?
1 answer:
A Punnett square is used to find out the possible genotypes of the next generation after a cross from 2 parents.
Usually, the letters outside the box are the genotypes of the parents, and the letter inside is the possible genotypes of their next generation.
The image inserted is an example of a Punnett square (made in MS word). It shows the cross of parents with genotypes Aa, and thus leads to possible next generation with genotypes of either AA, Aa or aa.

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.
Option A
<u>Explanation:</u>
According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.
In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.
So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.
