Answer:

Extra chromosome, missing chromosome or damaged chromosomes

Explanation:

Genetic disorders can be seen/detected from a karyotype photograph. a Karyotype represents the number and visual appearance of the chromosomes in the cell nuclei of an organism.

Karyotype is a laboratory technique that is used to produce the image of chromosomes of an individual in the laboratory . this technique is used to detect the presence of genetic disorders in an individual because and individual is supposed to have 26 pairs of Chromosomes and if it is less or more in the Karyotype its means there is a genetic disorder in the individual.

Answer:

The correct answer is: extra chromosomes, missing chromosomes, and/or damaged chromosomes.

Explanation:

Chromosome abnormalities are a group of genetic disorders characterized by abnormalities in their chromosomes, whether structural or numerical. This type of condition can be detected by a karyotype.

A karyotype is a laboratory technique used to observe all the chromosomes of an individual to see if there are any problems in it. A karyotype is a picture of all your chromosomes.

A normal karyotype shows 23 pairs of chromosomes (46 in total).

When there's an extra chromosome, it receives the name of trisomy (+ the number of the chromosomal "pair" where there's the extra chromosome). For example: Trisomy 21 - Down Syndrome.

When there's a chromosome missing, that is called monosomy (+ the number of the pair where there's a chromosome missing).

Damaged chromosomes can lead to loss of genetic material or translocation of said information.

How does independent assortment increase genetic variation in Meiosis?

KIM [24]

Answer:

Independent assortment produce new combinations of alleles.

Explanation:

In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.

What are the four biological compounds in living things?

sergejj [24]

There are more than simply 4 biological compounds in the human body. I suppose to categorise, the question is hinting towards the molecules like Carbohydrates ( Poly and mono saccharides ) Proteins ( Polypeptides Made of amino acids) and Fats. There is also water, but I'm hesitant to class that as a biological compound, as it's not organic.
