9. use the rule of multiplication to calculate the probability that a particular f2 individual will be homozygous recessive or dominant.

Complete: (1/2 dominant. + 1/2 recessive.)2

Homozygous. recessive.: 1/2 recessive. x 1/2 rec. = 1/4 rec.-rec.

Homozygous. dominant.: 1/2 dominant. x 1/2 dominant. = 1/4 dom.-dom.

Step-by-step explanation:

First, let us understand what the rule of multiplication is all about:

Basically, the rule of multiplication is a rule that states that there is a probability that two independent parallel event will eventually meet at a point.

Referring back to the question and applying the rule of multiplication,

we have,

Complete: (1/2 dominant + 1/2 recessive.) 2

Homozygous. recessive.: 1/2 rec. x 1/2 rec. = 1/4 recessive.-rec.

Homozygous. dominant.: 1/2 dom. x 1/2 dom. = 1/4 dom.-dom.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
