Answer: f. only b. and c. are examples of homozygotes

Explanation:

Diploid cells (all non-reproductive cells) have two copies of each gene, called <em>alleles</em>, one obtained from the father and one from the mother. In genetics, an organism is a homozygote for a gene if both alleles are the same. In contrast, heterozygotes have different alleles for the same gen.

Genes are represented with a letter, and you can differentiate between <em>alleles </em>if the letter is uppercase or lowercase.  

For example, if you wanted to represent the gene that encodes a flower color, you could call A the 'red' version of it and a the 'blue' version of it. A plant would be homozygote for that gen if it had the same version for both alleles, AA or aa.
