I think its C.
I hope this helps and please do correct me if im wrong.
Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.
3) The punnet square for cross between these parents can be shown as follows:
B b
B BB Bb
B BB Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).

Estimates of current rates of extinction indicate that rates may be greater than extinction rates seen in the fossil records.
<h3>What is extinction of species?</h3>
Extinction of species refers to the event in which species of organisms are entirely wiped from existence either by man-made causes, natural disasters or disease.
The recent industrial age and many technological advancements by man has resulted in rapid extinction of species .
Estimates of current rates of extinction indicate that rates may be greater than extinction rates seen in the fossil records.

The reptile produce few offsprings having no unique traits, and the vegetation as well changes quickly so that it can be protected from the reptile species.
Explanation:
Majority of the reptiles lay eggs or give birth to young ones such as squamates , this is done in two ways such as by keeping the egg inside the body of the mother or by developing offsprings without any formation of eggs. Climate change is having an adverse effect on the reptiles , a physiological as well as ecological change is occurring as a result reptiles as well as other species are in danger. Climate change is having an adverse effect on snakes , that is, there is fall in range size of snakes.
