What term refers to an individual’s genetic makeup passed to offspring?

• A. Genotype
• B. Phenotype
• C. Karyotype
• D. Allele

Answer: (A)

The term that refers to an individual’s genetic makeup passed to offspring is genotype. The genotype encompasses all the genetic information present within an individual, including the various alleles they inherit from their parents. This genetic blueprint determines the potential traits and characteristics that could be expressed in the offspring.

Understanding genotype is crucial in fields such as genetics, biology, and healthcare because it directly influences an individual’s predisposition to certain diseases and traits. For example, a fundamental concept in genetics is that different alleles can lead to variations in physical traits, susceptibility to illness, and other hereditary characteristics, all of which stem from the genotype.

In contrast, phenotype represents the observable traits and characteristics that result from the interaction between the genotype and the environment. The karyotype involves the complete set of chromosomes, while alleles are specific versions of a gene that may differ among individuals but do not encompass the entire genetic composition. Thus, the genotype is the most comprehensive term when describing the genetic makeup passed on to offspring.
