Sorry... I accidentally delete the former question.
# 1 Chromosome
A
B
# 2 Chromosome
a
B
What is the genotypes of heterozygous can # 1 and # 2 form?
Please explain it to me. Thanks a lot.

Heterozygous means that the two alleles for a trait do not match. Alleles are the different forms of a gene for a trait.
This individual has the alleles A and a for one trait. The genotype Aa is heterozygous because the alleles are different from each other.
This individual has the alleles B and B for a second trait. The genotype BB is homozygous because the alleles are the same.
More examples of heterozygous genotypes: Rr, Hh, Tt, yY, gG
More examples of homozygous genotypes: RR, HH, TT, yy, gg
Homo- means same. (homozygous = same-o-zygous)
Hetero- means different or other. (think of the t's in these words)

. . . A B
---+------------------------

Does this look familiar?
