Genes Flashcards
1
Q
Dominant gene
A
Stops other genes from showing when its present (Capitals B, D)
2
Q
Recessive genes
A
Doesn’t show if dominant is present (lower case b, d)
3
Q
Homozygous
A
Pair of alleles for a trait are the same
2 dominant genes- (BB, DD)
2 recessive genes- (bb, dd)
4
Q
Heterozygous
A
One dominant and one recessive gene for that trait (Bb, DD) dominant gene is shown
5
Q
Genotype
A
The allele/gene combo for each trait ( BB, Bb, bb)
6
Q
Phenotype
A
The actual trait/characteristic that shows (Brown eyes, blue eyes)
7
Q
Allele
A
Different forms of genes for each trait
ex. Long + short
