Question

what is considered to be the basic unit of inheritance?

a.) gamete
b.) karotype
c.) allele
d.) gene

Explanation:

Define the basic unit of inheritance

In Behavioral Genetics and general biology, the basic physical and functional unit of heredity is the gene. Genes are made up of DNA and act as instructions to make molecules called proteins.

Analyze the given options

• a.) Gamete: A reproductive cell (sperm or egg) containing a haploid set of chromosomes. It is a cellular vehicle for inheritance, not the basic molecular unit.
• b.) Karyotype: An individual's collection of chromosomes, or a laboratory image of those chromosomes.
• c.) Allele: A variant form of a gene. While alleles represent the specific versions of a trait, the gene itself is the fundamental unit.
• d.) Gene: The fundamental physical and functional unit of heredity.

Select the correct option

Since a gene is defined as the basic unit of inheritance, option (d) is the correct choice.

Answer:

• a.) Gamete
• b.) Karotype
• c.) Allele
• d.) Gene (Correct answer)
