pThe probability of having an offspring with both the dominant phenotypes for both genes is equal to the product of the individu

Elena-2011 [213]

The product probability rule states P(A∩B) = P(A) x P(B). In the exposed example, the probability of having a dominant phenotype is 9/16.

<h3>What is the product probability rule?</h3>

The product probability rule allows us to calculate the probability of occurrence of event A and event B at the same time.

It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.

This rule is based on the dependence or independence of the events. If two events A and B are independent of each other, the occurrence of one of them does not affect the occurrence of the other one.

For independent events, the rule establishes that, given two different events A and B, the probability of occurrence of both together is

P(A∩B) = P(A) x P(B)

The probability of inheriting one of the alleles from each parent is 0.5 (beacause each parent has two alleles).

According to this, the probability of having a dominant phenotype for both traits depends on the paretal genotypes.

For instance, let us analyze the cross between two dihybrid individuals AaBb x AaBb.

Assuming the involved genes code for different traits and both are independent genes, for easier calculations, we can perform crosses that involve each of the genes separately -events-, and then multiply de results according to the genotype and phenotype we are interested in (A-B-)

Gene A

Parentals) Aa x Aa

Gametes) A a A a

Punnett square) A(1/2) a(1/2)

A(1/2) AA(1/4) Aa(1/4)

a(1/2) Aa(1/4) aa(1/4)

F1) Genotype

1/4 AA ⇒ 1/2A x 1/2A

2/4 = 1/2 Aa ⇒ (1/2A x 1/2a) + (1/2A x 1/2a)

1/4 aa ⇒ 1/2a x 1/2a

Phenotype

3/4 A- ⇒ 1/4AA + 2/4Aa

1/2 aa

Gene B

Parentals) Bb x Bb

Gametes) B b B b

Punnett square) B b

B BB Bb

b Bb bb

F1 Genotype

1/4 BB ⇒ 1/2B x 1/2B

2/4 = 1/2 Bb ⇒ (1/2B x 1/2b) + (1/2B x 1/2b)

1/4 bb ⇒ 1/2b x 1/2b

Phenotype

3/4 B- ⇒ 1/4 BB + 2/4 Bb

1/2 bb

The probability of having a dominant genotype and phenotype for both traits is,

Genotpe AABB ⇒ 1/4 AA x 1/4 BB = 1/16 AABB

Phenotype A-B- ⇒ 3/4 A- x 3/4 B- = 9/16 A-B-

Why does the United States experience winter during the months of November through early March

Ghella [55]

The United States are entirely located in the Northern Hemisphere. It is bordering Canada on the north, and the air masses that form over it have big influence on the climate of the United States. Most of the United States falls under the influence of the air masses coming from the north, with only the southern parts of the east and west coastlines not being heavily affected. The air masses that form over Canada are cold continental air masses. They move towards south, thus toward the United States in November, quickly pushing the warmer air masses, and replacing them, bringing in cold weather conditions, which last until March.
