vichka [17]

Answer:

a. Genotype of male parent= BbNn

Genotype of female parent: bbnn

b: Progeny ratio= 1: 1: 1: 1

c: 1/4

Explanation:

a. Genotype of male parent= BbNn

Genotype of female parent: bbnn

b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.

Gametes formed by female parent: All gametes with "bn" alleles.

c.  The probability that the offspring will have a genotype of Bbnn=

Bb x bb= 1/2 Bb: 1/2 bb

Nn x nn= 1/2 Nn: 1/2 nn

Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.

The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.

The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
