Answer:
69.2 g
Explanation:
By using the Breeder's Equation we have that
[tex]h^{2} =\frac{M_{2} - M_{}}{M_{1} - M_{}}[/tex]
M is the mean of weight of parental variety (60g)
M2 is the mean weight of the progeny (?g)
M1 is the variety of the selected variety (80g)
h2 = 0.3
Replacing the values in Breeder's Equation we have
[tex]0.46 =\frac{M_{2} - 60g}{80 - 60}[/tex]
M2 = 69.2 g
