Question
What Chromosomes Tell Us
A karyotype is the complete set of chromosomes of an individual. This is a picture of the human chromosomes and as expected there are 46 chromosomes. The number of chromosomes in human cells is 46 with 22 autosomal pairs, one of each from the mother and one of each from the father, and 2 sex chromosomes Females have 2 X chromosomes and males have an X and a Y chromosome. The only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome. This image is called a karyogram. A karyogram allows a geneticist to determine a person's karyotype: a pictorial representation of their chromosomes.
Question 1
Which of these does not correctly explain why there are pairs of chromosomes in this karyotype?
Responses
A Each individual inherits one of each pair from each parent.Each individual inherits one of each pair from each parent.
B This karyotype represents human cells after fertilization.This karyotype represents human cells after fertilization.
C Gametes each contain a pair of chromosomes.Gametes each contain a pair of chromosomes.
D Humans reproduce via sexual reproduction.Humans reproduce via sexual reproduction.
Question 2
Imagine that this is your karyogram, showing your chromosomes. What information would your karyogram give scientists about you? All BUT ONE could apply.
Responses
A Your gender.Your gender.
B Your personality.

### Question 1
The correct answer is:
**C** Gametes each contain a pair of chromosomes.
This statement is incorrect because gametes only contain one copy of each chromosome (haploid) and do not have pairs of chromosomes. In humans, gametes (sperm and eggs) contain 23 chromosomes, which include one of each of the 22 autosomes and one sex chromosome.

### Question 2
The correct answer is:
**B** Your personality.
A karyogram provides information about an individual's chromosomes, such as their genetic makeup and gender, but it does not provide any information about personality traits. Personality is influenced by a combination of genetic, environmental, and social factors, and cannot be determined solely from a karyotype.
