Q

Give some advantage of AI

A
  • Superior male animals can be used very effectively.
  • Al controls venereal and other
    diseases

17
Q

Give some disadvantage of AI

A

Venereal and other diseases can be transmitted by technician’s carelessness in farms.

18
Q

The process by which semen is separated by sex and Can help determine sex of an individual during Al or ET

A

Semen sexing

19
Q

The process of fluorescent dye is added to sperm DNA, cells with X- chromosomes fluoresce differently from those with Y-chromosomes

A

Flow cytometry

20
Q

It measure the difference and the information directs the machine to rapidly sort the cells

A

Lasers and light detectors

21
Q

it developes individual from a fertilized union of a sperm and ovum

22
Q

It is a Growing embryos are transferred into a surrogate

23
Q

Benefits of ET

A
  • can save superior femals for producing eggs
  • can be frozen and preserve
24
Q

It is a technique to divide the embryo into equal halves then culture about 7 hours before transfer

A

Embryo splitting/ bisection

25
Q

It is used to split embryos

A

micromanipulator

26
Q

What are the ways of sexing

A
  1. by PCR method
  2. by LAMP method
  3. by Chromosomal analysis/karyotyping
27
Q

What is PCR

A

Polymerase Chain
Reaction

28
Q

What is LAMP?

A

Loop- Mediated
Isothermal Amplification

29
Q

Characteristics of Embryo Sexing Using LAMP Method

A
  • Simple
    - isothermal amplification. No
    denaturing steps required
  • rapid
    - amplification completes in 15-16
    minutes
  • specific
    - detection can be done by judging
    presence
  • cost effective
    - use one type of DNA
    - no special reagent and equipment
    is required
30
Q

ways of Cryopreservation of Embryo

A

Freezing
Cryopreservation

31
Q

defined as the solidification

The solution is become a glass

A

Vitrification

32
Q

embryo production method for embryo transfer to the recipient

A

In vitro fertilization

33
Q

When did Chang discovered the concept that capacitation of the spermatozoon was necessary for in vitro fertilization.

34
Q

It allows a large quantities of embryos to be produced at low cost

A

Significance of IVF technology

35
Q

True or false

Somatic cells needs to be fertilized before mating

A

False kasu diploid na yung chromosome number

36
Q

exact copy of an organism down the genetic level

37
Q

What animals were produced in cloning

A

Sheep - dolly
Cat - CC
Cattle - KC

38
Q

Benefits of cloning

A

can have superior herds of superior, identical animals with desired traits

39
Q

Disadvantage of cloning

A

Loss of genetic variably
Expensive
Requires technical skills

40
Q

Also know as cloning

A

Somatic cell transfer
