Lecture 19: Extensions of Mendelian Genetics Flashcards
1
Q
What is the probability of getting ssyy from SsYy x SsYy
A
1/16 (independent events)
2
Q
What does polymorphic mean and how does this relate to genes
A
It means occurring in several different forms, in particular with reference to species or genetic variation.
One gene –> Many alleles
3
Q
Define incomplete dominance
A
Blending of phenotypes
4
Q
Define co-dominance
A
When both phenotypes exist sisde by side within the organism
5
Q
What are polygenic traits
A
Phenotype controlled by many genes that have an additive effect
6
Q
Does the environment affect phenotype
A
Yes, it can. Nutrition can affect phenotype expression
