A karyotype is an organized profile of a person's .
The purpose of a karyotype is to .
We have total chromosomes: 23 from mom and 23 from dad.
How did you determine which chromosomes were a pair?
How many total chromosomes were present in the karyotype?
How many pairs of chromosomes were present in the karyotype?
A karyotype is an organized profile of a person's chromosomes. Two chromosomes specify biological sex: XX for female and XY for male.
Does the karyotype you completed belong to a male or a female?
A karyotype is an organized profile of a person's .
The purpose of a karyotype is to .
We have total chromosomes: 23 from mom and 23 from dad.
Karyotypes are arranged based on homologous pairs of chromosomes.
What are homologous chromosomes?
Homologous chromosomes #1-#22 are called chromosomes and these .
The two sex chromosomes are X and Y.
What sex is the individual in the karyotype above?
The two sex chromosomes are X and Y.
What sex is the individual in the karyotype above?
Deletions occur when a piece of the chromosome
Duplications occur when a piece of the chromosome
Inversions occur when a piece of the chromosome breaks off, then
Translocations occur when a piece of the chromosome breaks off, then
What is a nondisjunction anomaly?
Two types of Nondisjunction Anomalies
| Draggable emne | arrow_right_alt | Korresponderende emne |
|---|---|---|
Monosomy | arrow_right_alt | This is when there is an extra chromosome instead of the normal pair of 2. |
Trisomy | arrow_right_alt | This is when there is only 1 chromosome instead of two. |
We use the following notation to describe an individual’s karyotype:
Total number of chromosomes, Sex chromosomes, any extra or missing autosomal chromosomes.

If you were looking at your own karyotype, where do your chromosomes come from?
If one chromosome in a homologous pair contains the gene for hair color, hair texture, and skin color, what genes would the second chromosome in the pair contain?
Chromosomes are arranged in homologous pairs in the nucleus of eukaryotic cells. What is meant by the term homologous pairs?
