GENETIC BASIS OF INHERITANCE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is the genetic make-up of an individual organism.
A
Phenotype
B
Genotype
C
Karyotype
D
Chromosome
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: -A person’s genetic makeup is called a genotype.

Detailed explanation-3: -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-4: -Your genotype is your complete heritable genetic identity; it is your unique genome that would be revealed by personal genome sequencing. However, the word genotype can also refer just to a particular gene or set of genes carried by an individual.

Detailed explanation-5: -An organism’s genetic makeup is called its genotype, and it reflects all of the alleles, or forms of the gene, that are carried by the organism. Consequently, a test cross can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.
