Question

What is the best description of the individual represented by this karyotype?

1) A female who has experienced a mutation in which a gene segment was translocated to a new chromosome
2) A female who has experienced a deletion mutation of several base pairs from a chromosome
3) A male who has experienced a mutation in which extra base pairs were added to a chromosome
4) A male who has experienced a nondisjunction mutation of one or more chromosomes

Answer 1

The individual is best described as a male with a nondisjunction mutation, an error that occurs during cell division, resulting in an abnormal number of chromosomes, such as those seen in Klinefelter or Turner syndromes.The best description of the individual represented by this karyotype would be option 4:

Step-by-step explanation:

A male who has experienced a nondisjunction mutation of one or more chromosomes. This type of mutation typically involves either an extra chromosome or one fewer than the normal amount. Some examples of such abnormalities include Klinefelter syndrome (XXY genotype), which results in a phenotypically male individual with characteristics like small testes and reduced body hair, as well as Turner syndrome (XO genotype), which results in a female with short stature and sterility, among other features. Other aberrations such as deletions, insertions, or translocations can also be identified through a karyotype analysis.
