Сперматозоиды и яйцеклетки -гаплоидный (с одинарным набором непарных хромосом) , зигота -диплоидный (с парными хромосомами) наборы. Количество хромосом зависит от биологического вида. Зигота (оплодотворённая яйцеклетка) человека - 46 хромосом, соответственно, сперматозоиды и яйцеклетки -23. Бывают отклонения, но, это приводит к тяжелейшим генетическим заболеваниям. Например, к синдрому Дауна.

B) A lot of criminals never get caught.
C) On the form, she wrote her name, address and phone number.
D) It contained his name and address.
E) They plan their crimes very carefully.
F) He obviously wasn't the most intelligent man in the world, because he forgot to
cut holes for his eyes.
G) It wasn't real money.
What kind of people do you imagine when you think of criminals? If you watch lots of crime programmes and films on TV, you probably imagine people who are very intelligent but bad.
(1)____. Which means it’s difficult for the police to catch them. These people do exist, of course, but many criminals are not as intelligent as they often seem on TV There are many stories of real-life crimes where the police don't have to do very much to catch the criminal. (2)_____. For these people, crime definitely does not pay!
For example, a man and a woman were robbing a shop in Texas, in the USA. The man was pointing a gun at the shop assistant, who was putting the money from the till into a bag. While this was happening, the woman noticed an entry form for a competition on the counter. The prize was a lot of money, so she entered the competition. (3)_____. As you can imagine, it didn't take long for the police to catch them!

Then, so no one would recognise him, he put a paper bag over his head. (4)_____. He couldn't see the security guard, who came up to him, knocked the gun out of his hand, and arrested him.
In Britain, a 22-year-old man broke into an office in London to see what he could steal. You can imagine how happy he was when he found thousands and thousands of pounds on a desk. When he tried to put the money into his bank
account, the bank manager immediately called the police. (5)_____. The man had robbed a theatre. He stole fake money which had been used in a play!
Also in Britain, a gang of thieves stole several cars from a g3rage in Manchester. Unfortunately for the criminals, one of the thieves dropped his wallet at the scene of the crime. (6)_____. It didn't take the police long to find the cars and arrest the whole gang.
