mitosis
B
meiosis

A
mitosis
B
meiosis
3) What is genotype?
A
The physical characteristics you have

A
Two of the same chromosomes (example: two chromosome 21's)
B
Two different chromosomes
6) What are alleles?
A
Different versions of a gene
B
Different genes
C
Different chromosomes
7) What is gen loci?
A
Where a gene crosses over

prophase
B
metaphase
C
telophase
D
anaphase
