Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled
Tatiana [17]

Answer:

<h2>D)  610:190, round seeds:wrinkled seeds</h2>

Explanation:

Let round seed as R and wrinkled seed as r.

So the round is dominant (R) over wrinkled(r).

Hence , round is dominant and wrinkled is recessive rr.

Now cross between pure round (RR) and pure wrinkled (rr).

RR× rr

F1 offspring are:  Rr ( all)

Now cross between F1 offspring;

Rr × Rr

F2 are= RR, Rr, Rr and rr

RR and Rr = round

rr= wrinkled.

round to wrinkle ratio is= 3:1

So,  610:190; round seeds:wrinkled seeds  is the  expected result in the F2 progeny.
