Question

Which of the following is likely to be the result of polygenic inheritance?

a. freckles
b. an extra finger
c. human height
d. ABO blood type

Answer 1

c

Step-by-step explanation:

The correct answer here would be the human height.

Polygenic inheritances are traits or characteristics that can be passed on from one generation to another and are controlled by two or more genes. Polygenic traits do not show direct contrast (such as presence or absence) and are often quantitative rather than qualitative in nature. Examples include weight, height, skin color, etc.

The correct option is, therefore, c.

Answer 2

Answer: The correct answer to the question is option C

HUMAN HEIGHT.

Explanation: Polygenic inheritance also known as multifactorial inheritance can be defined as a phenomenon where two or more genes effect the expression of a trait or one trait. Or we can say it is when a single characteristic is controlled by more than two genes.

Polygenic inheritance brings about continuation in variation,when one gene is controlling the expression of a trait,the number if phenotypes that is is expressed is then limited to recessive or dominant phenotype.

Aside human height,other examples of Polygenic inheritance are;weight,human color, human intelligence,eye color etc.
