Since a karyotype is a picture of the entire organism's chromosomes and since all species have a different number of chromosomes it makes it easy to figure out what species you are looking at just by looking at the karyotype.
it is uncertain because there were some species that werent discovered since 2006 so who knows if some had died too?
A new species entering a geographical area is called and invasive species. These new species may soon take over since they may not have any natural predators, or enemies.
There are many advantages and disadvantages of genetics. The main advantage is that positive traits are passed from parents to offspring. This keeps a species alive. The downside is that negative traits are sometimes also passed along. This can result in serious deformities, illnesses, or death.
If you live in the United States, it is illegal to keep grackles as pets since they are a native species.

Earth is thought to be 4.5-4.6 billion years old.
Darwin had a somewhat eclectic education; he started out being trained in medicine, then moved to theology with natural history being a hobby. During his journey on the Beagle he described himself as a geologist; he'd been strongly influenced by Lyell's Principia Geologica and was seeing the world through a geologist's eye. His shipmates called him "Philosopher". Before the publication of The Origin of the Species, Darwin did some research on barnicles - this was partly to establish himself as a "serious" scientist - he was considered an authority on barnicles. After the publication of Origin, he was widely considered a naturalist and has been ever since.
The student magazine "Business Today" has been in publication since 1968, and is the largest student run magazine in the United States. Another publication with the identical title is an Indian business magazine which has been in publication since 1992.
15 years have passed since 1995.
No. Mitochondrial diseases are passed on only by mothers. So, she will pass it to her son. But her son will not be able to pass it to his children, since mitochondrial diseases are passed solely by women. Most (if not all) mitochondrial DNA are of maternal origin.
Since Arabic verse doesn't have chromosomes I'm going to assume you mean 'Gazelles'. As for chromosome number, it depends on which species of gazelle you're talking about. The publication in the link below suggests diploid numbers ranging from 30 to 58.

A homeobox gene controls the development of a specific structure in an organism. These gene sequences are found in many species (from flies to humans) and can indicate a very distant common ancestor, since one ancient species might have passed on one homebox gene to two separates species.
