What does hetrozygous and homozygous mean

Biology
1 answer:
natali 33 [55]3 years ago
5 0
In genetics when an organism is heterozygous that means that it contains 2 different alleles for a specific gene, heterozygous refers to the genotype 
Homozygous means the organism carries 2 of the same alleles.

For example there are two alleles for the gene of eye color 
B- is the dominant allele for brown eyes 
b- is the recessive allele for blue

So if a person's genotype is like Bb then he is heterozygous
but if he is like BB or bb then he is homozygous
