Answer:
An organism has a homozygous dominant trait if he has a BB allele.
Explanation:
An organism with two copy of same allele BB or bb considers as homozygous. These homozygous alleles can be recessive bb which is generally masked by dominant if present in combination or dominant BB in nature. Dominant characters or traits are commonly shown by capital letters and recessive traits are shown by small letters. Dominant traits generally appear more then recessive in phenotypes.
