When scientists predicted a scenario just like test-tube babies 30 years ago, it shocked us, but now it is an acceptable routine to most people. According to the journal Nature “Making Babies: The Next 30 Years”, newborns and 100-year-old can have children; labs will generate sperm and eggs for anybody; human embryos will be easily made by pluripotent stem cell; “Genetic cassettes” will be inserted to correct any genetic diseases or mutation; and In Vitro Fertilization (IVF) will become as cheap as $100.
But don’t you thing the old-fashioned way is cheaper and more fun?

According to researchers from Queen Mary’s School and Karolinska Institute in Stockholm, genetics and environmental factors which are specific to an individual (biological processes such as different hormone exposure in the womb) are the important determinants of homosexuality. Finding a single ‘gay gene’/ gene for heterosexual behaviour is influenced by a mixture of genetic and environmental factors, therefore it is very complicated.
The overall study proved that genetics accounted for around 35% of the differences between men in homosexual behaviour and other individual-specific environmental factors are accounted for 64%.
