Answer:
It's true...
Explanation:
Under the light of Mendel's laws of segregation and independent assortment, the ratio of the hetrozygous alleles always remain constant no matter what the circumstances are.
In the case of a dominant allele, it is very easy to be selected even when joined with a recessive part because that's the way of nature and in hetereozygous condition only the dominant phenotype appears and recessive expression gets masks din the process. It means it requires only one dominant parent to be major in the population. However, in the case of recessive allele, it's phenotype only appears when both of the parent recessive alleles are equally participating. That's why the recessive population is very low due to less rational selection.
Answer:

and this can cause tumors in the body with the uncontrollable growth of the cancer cells
The mating is the first event that happens in the development of a new organism because you may have A lion and a word you know that's not possible that would be a possible new organism that have not been formed yet but the mating would be the first thing that would happen
