Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.

Answer:
Yes.
Explanation:
Parallel circuit are those types of circuits in which break in one branch does not prevent the flow of current in the circuit and the current can still flow through another branch because there are more ways through which the current moves to other sources while on the other hand, series circuit refers to those circuits in which break in one branch can prevent the current flow in the circuit and the other sources can't receive current due to broken of the connection.
