Solution

The correct option is B

Dominant, recessive


In Mendelian convention, a capital letter is used to denote the dominant allele of a gene and a small letter for the recessive allele of the gene. E.g. 'Y' is the dominant allele responsible for yellow seed coat while 'y' is the recessive allele responsible for green seed coat in pea plants.
