- What happens when chromosomes do not segregate properly?A girl and a boy were born to a young married couple. The girl is absolutely healthy. The examination of the boy's karyotype has shown 46 chromosomes. But one of the chromosomes of the 15th pair is longer than normal as a part of a chromosome from the 21st pair has joined it. How many autosomes and sex chromosomes are in the boy's karyotype? Name the type of the mutation. Is it possible to consider this pathology an inherited disorder?In the classic "X" figure of the chromosome, is the whole X from one parent, or is one side of the X from the mother and the other side from the father?
