Question

What is the pattern of inheritance for polygenic trait?

• A. Non-mendelian inheritance pattern
• B. Autosomal dominant pattern
• C. X-linked recessive inheritance pattern
• D. Mendelian inheritance pattern

Hint:

Polygenic inheritance refers to traits that are influenced by multiple genes and often show continuous variation. Unlike Mendelian traits, polygenic traits do not follow simple dominant-recessive inheritance patterns.

Answer 1

The Correct Option is A

Multiple genes, often on separate chromosomes, govern polygenic traits. These traits deviate from simple Mendelian inheritance, exhibiting continuous variation and often interacting with environmental influences. Consequently, they display a non-Mendelian inheritance pattern.Human characteristics such as skin pigmentation, stature, and body mass are illustrative examples of polygenic traits, shaped by the interplay of numerous genes with diverse dominance and interaction levels.Therefore, the accurate classification is Non-Mendelian inheritance pattern.
