Why do mass extinctions wipe out species more or less randomly? See Section 25.4 (Page 512) . They are caused by exceptionally harsh, short-term conditions.

Why do mass extinctions wipe out species more or less randomly?

Why do mass extinctions wipe out species more or less randomly? They are caused by exceptionally harsh, short-term conditions. A mass extinction occurs when at least 60 percent of species are wiped out within 1 million years. _____ is rapid speciation under conditions in which there is little competition.

What is the primary cause of aneuploidy in humans?

For some time, researchers have known that most aneuploidies result from the nondisjunction of chromosomes during meiosis. In recent years, scientists have been able to more precisely pinpoint the causes of aneuploidy by using polymorphic DNA markers to follow individual chromosomes.

Which of the following is an example of aneuploidy?

Examples of aneuploidy are trisomy 21 and XYY Klinefelter’s Syndrome.

What type of disease is Klinefelter syndrome?

Klinefelter syndrome is a sex chromosome disorder in boys and men that results from the presence of an extra X chromosome in cells.
