Question

what biological concept was mendel studying when he crossed pea plants many times over many generations?
imbalance in ecosystems
predator - prey relationships
dominant and recessive traits
male and female genetic differences

Explanation:

Mendel's pea - plant experiments focused on how traits are passed from one generation to the next. He discovered that some traits are dominant (expressed when present) and others are recessive (only expressed when two recessive alleles are present). Ecosystem imbalance and predator - prey relationships are ecological concepts, not related to Mendel's work. Mendel's experiments did not specifically target male - female genetic differences in the way described in the option. His key contribution was to dominant and recessive trait inheritance.

Answer:

dominant and recessive traits
