Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a genotype?
A
Set of genes carried by the organism, the “genetic” make-up (letters).
B
Physical expression of the genes, the way the trait shows.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.

Detailed explanation-2: -Very quick rehash (review): genotype = the genes of an organism; for one specific trait we use two letters to represent the genotype. A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).

Detailed explanation-3: -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-4: -Genotype refers to an organisms genetic makeup, or genes. It is coded in DNA, and is often represented by two alleles (two letters, like AA or Aa).

Detailed explanation-5: -The different types of genotypes are-homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp).
