What was gregor mendel’s main contribution to science? a. he cultivated unusual flower species. b. he is considered the father of genetics. c. he researched the best-tasting peas. d. he proposed a theory of blended traits.

Gregor Mendel’s proposed the theory of blended traits which is considered as main contribution to science.

Option D

Explanation:

He experimented with the seven contrasting traits of the pea plant and came up with theories and laws pertaining to the segregation of characters. He noted that the F2 generation of the pea plant was having traits which were composed of dominant, recessive as well as new trait due to co-dominance.  

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
