Question

what does "Parents can choose to screen embryos created via in vitro fertilization (IVF) for sex or diseases, a process known as pre-implantation genetic diagnosis” (Ghose)" mean?

Answer 1

parents can check if the embryo has a disease

if it does, they can terminate the pregnancy

some of these are caused by a change in a single gene known as a single gene disorder

if one or both parents are carriers of a genetic disorder, they have a chance of passing it to their children even if they themselves are healthy.
