The platypus is not only weird to be duck-billed, venomous and a mammal that lays eggs—it has weird genetics too. Many mammals have actually two intercourse chromosomes, however the platypus has ten! Why? How can it works? And do these extra intercourse chromosomes make the platypus sexy that is extra? View to learn!
Unique compliment of Professor Jenny Graves for helping us produce this movie.

Say hello into the platypus, among the strangest pets on the planet. It lays eggs it isn’t a bird. It produces milk but does not have any nipples. It offers a skeleton just like a reptile. And it is one of many only venomous animals on the earth. Along with all that, it offers five times as many intercourse chromosomes even as we people do. Oh yes. Let’s discuss platypus intercourse.
First, however, a fast breakdown of intercourse chromosomes in people.
Our DNA is organised within 23 pairs of those small things that are wiggly looking chromosomes. One set comprises our intercourse chromosomes, which determine the intercourse we are born as. If both can be an X, you are female. If you have got one X plus one Y, you are male.
When we people opt to make an infant individual, the chromosomes split if you wish to generate a configuration that is new half from each moms and dad. The egg through the mother could have 23 of her 46 total chromosomes, including among the two Xes from her intercourse chromosomes.
The semen through the paternalfather may have 23 of their chromosomes, including either an X or a Y.
As soon as the egg and meet that is sperm in the event that semen carried an X chromosome, it is a woman. If a Y was carried by it, it really is a kid.
Therefore it’s a rather reasonable process. It does not have to get any longer complicated than that. Continuer la lecture
