1
Q
Define gene
A
A sequences of bases on a DNA molecule that codes for a protein resulting in a characteristic
2
Q
Define allele
A
A version of a gene
3
Q
Define genotype
A
The alleles a person has
4
Q
Define phenotype
A
The characteristics displayed by an organism
5
Q
Define dominant
A
An allele whose characteristic appears in the phenotype even if there is only one copy
6
Q
Define recessive
A
An allele whose characteristic only appears in the phenotype if there are two copies
7
Q
Explain incomplete dominance 2
A
- When a trait from a dominant allele isn’t completely shown over trait produced by the recessive allele
- So both alleles influence phenotype
8
Q
Define homozygote
A
An organism that carries two copies of the same allele for a certain characteristic
9
Q
Define heterozygote
A
An organism that carries 2 different alleles for a certain characteristic
10
Q
Explain carrier - 2
A
- Individual that has one dominant and one recessive allele for a recessive allele disease
- They do not have the disease but carry a copy of the allele for it
