1
Q
Define: LOCUS
A
- specific position of a gene on a homologous chromosome
2
Q
Define: ALLELE
A
- alternative version of a gene at a particular locus
- controls same character, produces different traits
3
Q
Define: DOMINANT
A
- allele has same effect on phenotype in both homo and heterozygous state
4
Q
Define: RECESSIVE
A
- allele only has effect on phenotype in homozygous state
5
Q
Define: CO-DOMINANT
A
- pair of alleles that both affect phenotype in heterozygous state
6
Q
Define: HOMOZYGOUS
A
- having 2 identical alleles at a gene locus
- for diploid organisms
7
Q
Define: HETEROZYGOUS
A
- having 2 different alleles at a gene locus
- for diploid organisms
8
Q
Define: PHENOTYPE
A
- characteristic of organism (external feature)
9
Q
Define: GENOTYPE
A
- pair of alleles possessed
