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: -Purebred-Also called HOMOZYGOUS and consists of gene pairs with genes that are the SAME. 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: -A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus. Therefore, a dihybrid organism is one that is heterozygous at two different genetic loci.

Detailed explanation-4: -If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.

Detailed explanation-5: -An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele. If the alleles are different, the individual is heterozygous.
