Genetic Information, Storage and Transfer Flashcards
1
Q
What is a genotype?
A
Set of genes you inherit
2
Q
What is a phenotype?
A
Individual characteristics and appearance
3
Q
How are characteristics determined?
A
- Can be determined only by genes (ABO blood group)
- Can be determined by genes and environment
- Some characteristics not determined by genes
4
Q
What are epigenetics?
A
The study or heritable changes in the phenotype without the alteration of DNA base sequence
5
Q
What is a genome?
A
the total amount of genetic material in one chromosome set
