Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best describes PGD?
A
identifies suitable embryos
B
uses gel electrophoresis
C
allele length is studied
D
shows locations of genes
Explanation: 

Detailed explanation-1: -Pre-implantation genetic diagnosis (PGD) is a technique that involves testing cell(s) from embryos created outside the body by IVF for a genetic disorder. Tests are carried out for the specific disorder that the embryos are known to be at significant risk of inheriting.

Detailed explanation-2: -Pre-implantation genetic diagnosis (PGD) is a reproductive technology used with an IVF cycle. PGD can be used for diagnosis of a genetic disease in early embryos prior to implantation and pregnancy.

Detailed explanation-3: -Pre-implantation genetic diagnosis (PGD) is a laboratory procedure used in conjunction with in vitro fertilization (IVF) to reduce the risk of passing on inherited conditions.

Detailed explanation-4: -Preimplantation genetic diagnosis (PGD) is a procedure used by fertile or infertile couples at high risk of transmitting a genetic condition and allows diagnosis of single gene disorders, chromosomal abnormalities or HLA typing in embryos prior to transfer and implantation.
