• Summary:
Scientists have obliterated the Y chromosome, the symbol of maleness in DNA, because they may be able to do everything without it. They discovered that mice with an modified Y chromosome, which consisted of just two genes, could still father babies. These mice were infertile, and they were able to have live offspring by using assisted reproduction, that it consisted of injecting genetic information from the sperm into an egg. It was shown that the mice and the offspring were totally healthy. It showed that it was still possible to reproduce with a modified Y chromosome, and this fact gives hope to men with these problems. Finally, they say that this finding could, one day, help infertile men.
• Opinion:
In this piece of news we can see that technology is developing very fast, and this fascinates me. Every time we get more solutions to our problems, and I am very happy that genetic problems could be solved in the future. I know a man who believe to be infertile, and I would be so proud and happy if this finding becomes a real solution.
• Words I have learnt:
Obliterated: esborrat
Maleness: masclisme
Albeit: encara
Offspring: descendència
