Question

gregor mendels research formed the basis of the field of
genetics.
dominance.
recessiveness.
selective breeding.

Explanation:

Gregor Mendel is known as the father of genetics. His experiments with pea plants (studying traits like flower color, seed shape etc.) led to the discovery of fundamental laws of inheritance (law of segregation, law of independent assortment). These laws laid the ground - work for the field of genetics which is the study of genes, heredity, and genetic variation in living organisms. Dominance and recessiveness are concepts within genetics (describing how alleles interact), and selective breeding was a practice before Mendel, but Mendel's work specifically formed the basis of genetics.

Answer:

genetics.
