In a population of tomato plants, mean fruit weight is 60 g and (h2) is 0.46. Predict the mean weight of the progeny if tomato plants whose fruit averaged 80 g were selected from the original population and interbred.

69.2 g

Explanation:

By using the Breeder's Equation we have that

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

M2 = 69.2 g

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
