Option (c) and (d) are correct
a and b are the recessive alleles represented in genotype AaBb.
An allele is a different nucleotide sequence that codes for the production of a gene product at the same location on a lengthy DNA molecule.
Recessive Allele : A particular allele that, when present alone, has no effect on the person. The expression of the trait requires the presence of two copies of the allele.
Dominant Allele : A dominant allele is a gene variant that will result in a specific phenotype even when there are other alleles present.
Genotype - The genetic configuration that determines the features that an organism inherits from its parents is known as a genotype.
Phenotype - The term "phenotype" refers to an organism's observable physical characteristics, such as its appearance, growth, and behavior.
Hence (a) & (b) are the recessive alleles represented in the genotype AaBb.
