Q
alleles
A
alternate forms of a gene
3
Q
homozygous
A
when genotype contains Same 2 alleles
4
Q
heterozygous
A
when genotype contains 2 different alleles
5
Q
true-breeding
A
all offspring have the same phenotype as parents
6
Q
hybrid
A
mix of genetic info
7
Q
multiple alleles
A
more than one gene
8
Q
incomplete dominance
A
when phenotype of heterozygous is “in between” the homozygous organisms
9
Q
codominance
A
both alleles expressed in heterozygote
10
Q
genotype
A
actual gene combination an organism contains
11

phenotype
A
how your genotype is expressed
12

autosomes
A
humans have 22 pairs
13
Q
gametes
A
sex cell that has 1 set of chromosomes
14
