Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
having two different genes for a trait (sometimes called hybrid).
A
protein
B
homozygous
C
heterozygous
D
genotype
Explanation: 

Detailed explanation-1: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene. The relationship between the two alleles affects which traits are expressed.

Detailed explanation-2: -Hybrid-Also called HETEROZYGOUS and consists of gene pairs that are DIFFERENT. Genotype is the actual GENE makeup represented by LETTERS. Phenotype is the PHYSICAL appearance of a trait, such as a YELLOW (or BLUE) body color.

Detailed explanation-3: -The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

Detailed explanation-4: -A hybrid trait is also known as a heterozygous trait, and is the pairing of a dominant and recessive allele. The dominant allele always dictates the phenotype of the trait.

Detailed explanation-5: -Heterozygous is a kind of organism that has different alleles present in its genotype for the same gene. For example, a pea plant might have both the alleles “Aa” in its genotype for seed texture, or round ("A") or wrinkled ("a") seeds.
