In the punnett square, fill in the shaded boxes with the alleles of each parent. use b for the
dominant allele (black fur) and b for the recessive allele (white fur).

the blue squares are B and the white squares are BB

A diagrammatic representation of a genetic cross in a square box that predicts the phenotype and genotype of the offspring from the parental cross are called Punnett square.

All the progenies will have black fur.

The cross can be explained as:

Given,

The cross between the black and white fur allele is attached in the image below.

According to the cross:

This can be explained as there was no white (bb) fur parent only male and female with black fur (BB) were crossed so all the progenies were having black fur.

Therefore, 100% black fur progenies were produced.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
