2. Biological Foundations of Development Flashcards
1
Q
What are gametes?
A
Sex cells (sperm and eggs)
2
Q
What is a genotype?
A
One’s actual genetic makeup
3
Q
What is a phenotype?
A
The expression of genotype, someone’s appearance
4
Q
What are dominant and recessive genes?
A
Dominant genes control the phenotype if present, while recessive genes only control the phenotype if both are the same
5
Q
What are additive genes?
A
Genes that share control of traits.
6
Q
What is polygenic inheritance?
A
The control of complex traits by many genes working together.
7
Q
What is epigenesis?
A
The view that there is a bidirectional interaction between one’s genes and environment
8
Q
What is reaction range?
A
The range of possible phenotypes for any given genotype.
