Question

a genetic factor that blocks another genetic factor
options: hybrid, recessive, self pollination, heredity, dominant

Explanation:

To solve this, we analyze each term:

• "hybrid" refers to offspring of different varieties, not blocking.
• "recessive" is a trait masked by dominant, not blocking.
• "self - pollination" is a reproduction method, not related to blocking genetic factors.
• "heredity" is the passing of traits, not a blocking factor.
• "dominant" genetic factors block (mask) recessive ones.

Answer:

E. dominant
