Question 10

Observing the occurrence of estrus

Answer 10

Question 11

Done via hormonal intervention

Answer 11

Fixed Time AI (FTAI)

Question 12

An assisted reproductive technology wherein ova are picked up via guided Ultrasonograpy (OPU)

Answer 12

In-Vitro fertilization

Question 13

As the sperm cells
touch down the cervix, it produces mucus rich in ________

Answer 13

Sialomucin & sulfomucin

Question 14

True or false less viscous mucus favors sperm transport as they can easily swim through the reproductive tract.

Answer 14

True

Question 15

Delivers spermatozoa to the fertilization site very shortly after copulation (15-30 mins)

Answer 15

Rapid Transport Phase

Question 16

Delivers spermatozoa to the ampulla in a more uniform manner over a sustained period of time (6-12 hrs)

Answer 16

Slow/Sustained Transport Phase

Question 17

Movement of sperm cells from one horn to another (usually during AI)

Answer 17

Intercornual transport

Question 18

Technology used to achieve pregnancy in procedures such as artificial insemination, in vitro fertilization and surrogacy

Answer 18

Assisted Reproductive Technology (ART)

Question 19

Introduction of sperm into the female’s uterus or cervix for
the purpose of achieving pregnancy through in vivo fertilization by means other than sexual intercourse

Answer 19

Artificial insemination

Question 20

a tool of assisted reproductive
technology against infertility. Eggs are removed from a female ovary and placed in
one of fallopian tubes, along with the male sperm.

Answer 20

Gamete Intra Fallopian Transfer (GIFT)

Question 21

Sperm is injected directly into the eggs in a laboratory. It is used if infertility originates from the male such as: Low numbers of sperm, Low sperm motility.

Answer 21

Intra Cytoplasmic Sperm Injection (ICSI)

Question 22

An assisted reproduction technology in which embryos are placed into the uterus of a recipient female (surrogate) animal to establish a pregnancy.

Answer 22

Embryo transfer

Question 23

Ovaries are collected from superior old stock, oocytes are aspirated and in-vitro fertilized the eggs. Then transferred to surrogate/recipient mother. Offspring born, grow and become champion of genetic quality.

Answer 23

In-Vitro Fertilization- Embryo Transfer (IVF-ET)

Question 24

Nucleus of the oocyte is
removed and injected/implanted by the diploid nucleus of a somatic cell. Master genes that have been shut down in the original cell is then activated resulting to the creation of a new but the same organism.

Answer 24

CLONING/Somatic Cell Nuclear Transfer (SCNT)
