Question

Please I need some help.

Dave is a botanist. He’s analyzing a new species of plant that grows more than 6 feet in height. The average height of this plant is normally 5 feet. To determine whether height is genetic, Dave breeds the tallest plants, which are 7.5 feet tall. If , Heritability= Response/Selection what’s selection?


A.

1.5


B.

2.5


C.

6


D.

7.5

Answer 1

7.5

Step-by-step explanation:

Answer 2

Option D, 7.5

Step-by-step explanation:

In this question,

Heritability is defines as Response divided by Selection

Here response = the height of the species produced as result of cross between the selected species

While selection = the height of the species selected for cross.

Since, Dave has selected the tallest plants ( which are 7.5 feet tall) for breeding, thus it can be referred as selection here.
