Question

Holandric gene is made of

• A. 14 bp
• B. 1400 bp
• C. 14000 bp
• D. 140,000 bp

Answer 1

The correct option is A 14 bp

The genes that are carried on the Y chromosome are called holandric genes. Holandric genes can only be passed by males onto their sons; they code for 'maleness' but sometimes cause rare conditions like hypertrichosis pinnae and color blindness. The defferential region of Y- chromosome carries only Y-linked or holandaric genes,e.g., testis determing factor(TDF). It is perhaps the smallest gene occupying only 14 pairs.

So, the correct answer is '14 bp.'
