Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The scientific term that refers to the gene combination of an organism.
A
Genotype
B
Allelotype
C
Phenotype
D
Monotype
Explanation: 

Detailed explanation-1: -Agenotypeis the genetic makeup of an individual organism. Biologists use the term genotype to distinguish from phenotype, which consists of the observable characteristics of an organism.

Detailed explanation-2: -An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).

Detailed explanation-3: -An individual’s genotype is the combination of alleles that they possess for a specific gene. An individual’s phenotype is the combination of their observable characteristics or traits.

Detailed explanation-4: -A person’s genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient’s clinical presentation.

Detailed explanation-5: -Genes are the fundamental units of heredity, and the genome is the organism’s ensemble of genes. The genotype is the individual organism’s unique set of all the genes. In a complex manner, the genotype governs the phenotype, which is the ensemble of all traits of the organism’s appearance, function, and behavior.
