In a heterozygous genotype, the ____ allele takes over in the phenotype.
A
recessive
B
dominant
C
lower case letter
D
both
Explanation: 

Detailed explanation-1: -In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed.

Detailed explanation-2: -An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

Detailed explanation-3: -Dominance affects the phenotype derived from an organism’s genes, but it does not affect the way these genes are inherited. Complete dominance occurs when the heterozygote phenotype is indistinguishable from that of the homozygous parent.

Detailed explanation-4: -So, the correct answer is D “Tt".
