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

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
