Sex determination: More complicated than you thought - Aaron Reedy Most mammals, like humans have an XY genetic system for determining sex where XX produces females and XY produces males. However, sometimes when sex chromosomes are dividing during meiosis, non-disjunction occurs and embryos are formed with numbers of sex chromosomes different from those that are typical. For example on occasion males have the sex chromosomes XXY or XYY. There are also sometimes females with a single X chromosome or an XXX combination of sex chromosomes. There are even sometimes individuals who are genetically XY, but due to male hormone insensitivity, develop some or nearly all female characteristics.
10 Incredible Chemical Reaction GIFs Explained We encounter thousands of chemical reactions every day: plants use them in photosynthesis, metals rust over time, and combustion reactions provide us with heat and light, among thousands of other daily uses. Chemical reactions occur when reactants transform into new substances, called products, through creating and breaking bonds between atoms. Sometimes the process creates some pretty wild effects. Check out our top 10 chemical reactions below: 1) Disintegration (Mercury Reacts with Aluminum) Genetics - Mrs. E's Biology Site In this unit, we will be studying Molecular Genetics (DNA & Protein Synthesis) and Mendelian Genetics (all those Punnet squares you know and love!). However, in order to learn how to apply all that genetics goodness and get to a level 5, we will start with a problem. In this problem, you are a doctor who specializes in genetic diseases seen in children.

First identical twins with different skin colour born in the UK Identical twins Amelia and Jasmine are thought be the first black and white twins born in the UK, despite coming from the same egg. The girls were born to mum Libby Appleby, 37, from West Rainton, County Durham who is white and her partner Tafadzwa Madzimbamuto, 40, who is black. They are identical or monozygotic twins, meaning they developed from the same zygote, which split and formed two embryos. Scroll down for video Libby Appleby, 37, from West Rainton, County Durham was told she wouldn't be able to tell her identical twin babies apart. But Jasmine (left) and Amelia were born with contrasting skin tones
