Introduction to Heredity

Question 8 • WI-Grade 8 Life Science A

Which describes a concept that was not previously known but was developed as a direct result of Mendel’s experiments with pea plants?

Answer
A
Organisms with a recessive trait can have a dominant allele for the trait.
B
All observable traits are dominant.
C
Organisms have more than one observable trait.
D
Organisms can be bred for specific traits based on a pattern of inheritance.

Explanation

Mendel’s experiments showed that traits are inherited in predictable patterns, which helped explain how parents can pass traits to offspring. That knowledge allows organisms to be bred for specific traits based on inheritance patterns, as choice D states. Selective breeding existed before Mendel, but his experiments revealed patterns that could guide it.
