In lentils, the C gene has two different alleles. CS CS homozygotes have spotted seeds, CD CD homozygotes have dotted seeds, and CS CD heterozygotes have seeds with both spots and dots. This indicates that _____.
The correct answer is "CS and CD are codominant"
This indicates that the "C" gene in lentils exhibits incomplete dominance or co-dominance. Incomplete dominance occurs when neither allele is completely dominant over the other, resulting in a blended or intermediate phenotype in heterozygotes. Co-dominance, on the other hand, occurs when both alleles are expressed fully in the heterozygote, resulting in a combined or mosaic phenotype.
In this case, CS CS homozygotes have spotted seeds, CD CD homozygotes have dotted seeds, and CS CD heterozygotes have seeds with both spots and dots. This suggests that neither the "S" allele nor the "D" allele is completely dominant over the other, and both are expressed in the heterozygote. This is a classic example of co-dominance or incomplete dominance in genetics.
