A
- Multiple alleles for the same gene,
- By polygenic inheritance
- The environment
2
Q
what is the locus?
A
The locus is the place on a chromosome where any particular gene is found
3
Q
What are multiple alleles?
A
More than two possible variants at a paricular locus
4
Q
How are polygenic phenotypic characters determined?
A
Determined by several interacting genes.
5
Q
What is digenic inheritance?
A
It is the inheritance of two pairs of contrasting characteristics at the same time
6
Q
what is the process of cell differentiation?
A
The process by which a less specialized cell becomes more specialized for a particular function
7
Q
what does co dominant mean and what does it produce?
A
It means that both alleles are expressed and produce a protein
