Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best describes a GENOTYPE?
A
The allele/genetic makeup of an organism.
B
The physical expression of a trait.
Explanation: 

Detailed explanation-1: -In one sense, the term “genotype”-like the term “genome”-refers to the entire set of genes in the cells of an organism. In a narrower sense, however, it can refer to different alleles, or variant forms of a gene, for particular traits, or characteristics.

Detailed explanation-2: -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-3: -A person’s genetic makeup is called a genotype.

Detailed explanation-4: -Our genetic makeup, also called our genotype, is decided by the pairs of alleles in our DNA. This elaborate genetic tapestry, including dominant and recessive alleles, are what help decide how we look and live day to day.
