Gene flow does not promote speciation, whereas season of fertility, natural selection, and genetic drift do.
The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
Answer:
1. Life, exist 2. pre-existing cells.
Explanation:
It occurs during Anaphase II, Telophase II, and Cytokinesis, when the sister chromatids separate so that there is 1 allele per gamete.
