Cross two pink snapdragons. What is the genotypic and phenotypic probability of such a cross?

Biology

SVEN [57.7K]3 years ago
5 0

Answer:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

Explanation:

This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.

According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

iren2701 [21]

Answer:

This question is incomplete; the complete part is:

What is the independent variable in this experiment?

A) The plant species

B) The amount of water that each plant gets

C) The amount of time

D) The different types of light the plants were put under.

The answer is D. The different types of light the plants were put under.

Explanation:

In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter in order to bring about a measurable response.

In this experiment, Suzie Q wants to know the effect of different colors of light on the growth of plants. The different types of light used are; white light, blue light, green light, red light. Therefore, the independent variable is the DIFFERENT TYPES OF LIGHT THE PLANTS WERE PLACED UNDER.

Yuki888 [10]

Answer:

3/8

Explanation:

I think I can help with completing the question.

Above each punnet square, the genotypes of the parents were given right? something like this:

Parent 1 fur genotype: Ff                             Parent 1 eye genotype: Ee

Parent 2 fur genotype: Ff                            Parent 2 eye genotype: ee

       F         f                                                              E        e

F     FF       Ff                                                    e     Ee      ee

f      Ff        ff                                                     e     Ee      ee

Probability of black fur if dominant is:               Probability of red eyes:

    3/4                                                                       2/4= 1/2

Probability of a trait combination such as black fur and red eyes is

3/4*1/2 = 3/8.
