This type of genetic transmission expresses the gene depending on whether it is from the mother or the father. ____________
Select one:
a. GENETIC IMPRINTING
b. SEX-LINKED GENES or X-LINKED INHERITANCE
c. POLYGENIC INHERITANCE or GENE-GENE INTERACTION
d. DOMINANT-RECESSIVE GENES PRINCIPLE
GENETIC IMPRINTING
This type of genetic transmission is carried on the X gene only, so boys are more likely to express the disorder because their Y chromosome is not able to counteract it. ____________
Select one:
a. GENETIC IMPRINTING
b. SEX-LINKED GENES or X-LINKED INHERITANCE
c. POLYGENIC INHERITANCE or GENE-GENE INTERACTION
d. DOMINANT-RECESSIVE GENES PRINCIPLE
SEX-LINKED GENES or X-LINKED INHERITANCE
This type of genetic transmission occurs when multiple pairs of genes work together to form a characteristic. ____________
Select one:
a. GENETIC IMPRINTING
b. SEX-LINKED GENES or X-LINKED INHERITANCE
c. POLYGENIC INHERITANCE or GENE-GENE INTERACTION
d. DOMINANT-RECESSIVE GENES PRINCIPLE
POLYGENIC INHERITANCE or GENE-GENE INTERACTION
This type of genetic transmission occurs because a certain gene always is expressed in favour of another one. ____________
Select one:
a. GENETIC IMPRINTING
b. SEX-LINKED GENES or X-LINKED INHERITANCE
c. POLYGENIC INHERITANCE or GENE-GENE INTERACTION
d. DOMINANT-RECESSIVE GENES PRINCIPLE
DOMINANT-RECESSIVE GENES PRINCIPLE
This test is given during the 10th to 13th week by taking a sample from the placenta. Results are ready in 10 days, but it has a slight chance of miscarriage.
Select one:
a. Amniocentesis
b. Chorionic villus sampling (CVS)
c. Ultrasound
Chorionic villus sampling (CVS)
This is given about seven weeks into the pregnancy. It involves scanning the womb with soundwaves.
Select one:
a. Amniocentesis
b. Chorionic villus sampling (CVS)
c. Ultrasound
Ultrasound
This is given during the 16th to 20th weeks using a needle to extract fluid. It is often used by older mothers and has a slight chance of triggering a miscarriage. It may take up to two weeks for results.
Select one:
a. Amniocentesis
b. Chorionic villus sampling (CVS)
c. Ultrasound
Amniocentesis
