What exactly does homozygous and heterozygous mean?
What is an allele?


Lets start from autosomal chromosomes:
Any gene which is NOT a sex gene is known as Autosamal genes or AUTOSOME.
Now we all have a pair of autosomal genes meaning 2 copies on each chromosome.
Allele is a series of 2 or more genes that occupy the same locus on a specific chromosme.
If the allele is the same sequence on the other (pairing) chormosomal locus then it is a homozygous pair,
If the allele is different then the cell is heterozygous for both alleles.
I hope I didn't add to the confusion :|
