If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?
Artemon [7]

Answer:

C. His mother carried at least one allele for that trait

Explanation:

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.

In the figure below, ΔMNO≅ΔPQR.What is the measure of ∠P? Show your work and explain your reasoning.
Juliette [100K]

Answer:

\huge\boxed{\sf P = 79.5\°}

Explanation:

<u>Given that:</u>

ΔMNO ≅ ΔPQR

That means

M ↔ P

N ↔ Q

O ↔ R

So,

∠P ≅ ∠M

Given that P = 3x + 20.4 and M = 5x - 19

3x + 20.4 = 5x - 19

Add 19 to both sides

3x + 20.4 + 19 = 5x

3x + 39.4 = 5x

Subtract 3x to both sides

39.4 = 5x - 3x

39.4 = 2x

2x = 39.4

Divide both sides by 2

x = 19.7

<u>Given that:</u>

P = 3x + 20.4

P = 3(19.7) + 20.4            (x = 19.7)

P = 59.1 + 20.4

P = 79.5°

\rule[225]{225}{2}

Hope this helped!
