The stage transferred into the uterus after induced fertilization of ovum in the laboratory is:

Explanation

The stage transferred into the uterus after induced fertilization of an ovum in the laboratory is typically the embryo. Let's go through each option and provide some explanation:a. Ova (egg): This is the female reproductive cell that is fertilized by a sperm to form a zygote. Ova are usually not transferred into the uterus.b. Embryo: After fertilization, when the sperm has successfully fused with the egg, it forms a zygote. This zygote then begins to divide and develop into an embryo. In the context of in vitro fertilization (IVF) or other assisted reproductive techniques, it is the embryo that is usually transferred into the uterus to facilitate pregnancy.c. Morula: The morula is a stage that follows the zygote. It is a ball of cells resulting from the rapid division of the zygote. Eventually, the morula will develop into a blastocyst, which is the stage that is usually transferred into the uterus during IVF.d. Zygote: The zygote is the product of the fusion of a sperm cell and an egg cell. It is the first stage of development after fertilization, but it is not typically transferred into the uterus. Instead, it undergoes further development into the morula and eventually the blastocyst or embryo.Correct Answer: The correct answer is b. Embryo. After induced fertilization in the laboratory, the resulting zygote develops into an embryo, and it is the embryo that is transferred into the uterus for implantation during assisted reproductive techniques like IVF.Summary: The stage transferred into the uterus after induced fertilization is the embryo. While the zygote is the immediate product of fertilization, it undergoes further development into the morula and then the blastocyst, which is what is typically transferred into the uterus during assisted reproductive procedures to establish pregnancy.
