Answer: Polygenic inheritance
Explanation:
Polygenic inheritance is a phenomenon that explains how a character like skin color show a range of more or less continuous variation due to many genes controlling it. And this is unlike Mendel traits that are controlled by single genes.
So, skin color in an individual is expressed as red hair and pale skin.
The biome concept organizes large-scale ecological variation. Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall.
Fertilization is the impregnation, the state when<span> a sperm cell penetrates the egg cell and the genetic material of both cells combines.
A few days after fertilization i</span><span>mplantation happens. Implantation is the attachment of the fertilized egg to the uterus, happens on average about 9 days after ovulation/fertilization (between 6 and 12 days) and is required for the fetus to continue to grow.</span>
