In pea plants, round peas are dominant (r) and shriveled peas are recessive (r), and yellow peas (shown as light gray in the punnett square) are dominant (y) and green peas (dark gray) are recessive (y). using this information and the partial punnett square shown, what is the phenotypic ratio of the offspring pea plants in this punnett square?

The right answer is 3:3:1:1

A Mendelian inheritance (classical or monogenic) is a transmission of a single gene in a dominant, recessive or linked to X (this is the case in this question, offsprings are made by crossing the genotypes between the two species).

Discoveries on the structure of DNA, the genetic code, the genome and the observation of genetic traits and diseases that do not comply with the laws of formal genetics (Mendelian inheritance) have led researchers to define other modes of transmission including those related to multifactorial and mitochondrial inheritance (non-Mendelian inheritance).

true is the final answer!
