pleiotropy

Question 7

sickle cell anemia genetic term

Answer 7

pleiotropy

Question 8

Homocystinuria genetic term

Answer 8

Pleiotropy

Question 9

turner syndrome genetic term

Answer 9

mosaicism

Question 10

klinefelter syndrome genetic term

Answer 10

Mosaicism

Question 11

an individual has cells that have different genotypes

Answer 11

mosaicism

Question 12

patients with same mutated genotype may or may not have phenotypic expression

Answer 12

Incomplete penetrance (BRCA1 mutation does not always result in breast or ovarian cancer)

Question 13

Blood groups: A, B, AB
HLA groups
genetic term

Answer 13

codominance

Question 14

one way DNA transfer via a fertility factor.
donation of single DNA strand containing fertility factor –> complementary DNA synthesis

Answer 14

conjugation

Question 15

bacteriophage (virus) transfers DNA from one bacterial cell to another

allows bacteria to acquire genes for virulence and antibiotic resistance

Answer 15

transductoin

Question 16

bacterium takes up exogenous DNA fragments

DNA fragments are integrated into the genome –> expression of encoded proteins

allows bacteria to gain virulence

Answer 16

Transformation
