Cards (19)

Section 1

(19 cards)

type AB

Front

- produces both A & B antigens on red blood cells - blood contains NEITHER anti-A nor anti-B antibodies

Back

timing of meiosis

Front

as eggs age with the mom, errors in chromosome number can occur

Back

type A

Front

- produce A markers (antigens) on the surface of every red blood cell - blood contains anti-B antibodies

Back

inheritance of alleles

Front

place of one particular gene on a chromosome - locus - homologous chromosomes have corresponding loci, but they may or may not contain matching alleles

Back

Huntington's Disease

Front

- simple dominant inheritance pattern - brain disorder - progressive, fatal

Back

monozygotic twins "identical"

Front

product of one egg + one sperm = one zygote (one set of DNA, so they are 100% genetically identical) (same alleles)

Back

simple, recessive disorder

Front

cystic fibrosis (defective protein thickens mucus)

Back

type B

Front

- produces B antigens on red blood cells - blood contains anti-A antibodies

Back

trisomy

Front

3 copies of a chromosome (in every somatic cell)

Back

type O

Front

- produces neither A nor B antigens (no markers) - blood contains BOTH anti-a and anti-B antibodies

Back

antibodies

Front

Y shaped proteins circulating in blood are produced by white blood cells, dock with specific antigens on foreign cells/objects to defend against them by clumping them together for destruction by other white blood cells - Y's hook on and clump (bacteria) big white blood cells come and destroys it

Back

"simple" inheritance

Front

only one gene involved, no environmental factors that are relevant, and only 2 alleles exist (one dominant, one recessive)

Back

sickle cell anemia

Front

- simple recessive inherited disorder - defective protein in red blood cells

Back

positive blood type

Front

- have Rh antigens on red blood cells - can receive blood from BOTH positive and negative donors

Back

dizygotic twins "fraternal"

Front

separate eggs fertilized by/fused with separate sperm -- 2 zygotes - same genetic similarity as any regular sibling (50%)

Back

antigens

Front

markers on cell surfaces

Back

crossing over

Front

exchange of corresponding portions of homologous chromosomes - produces chromosomes that contain mixtures of alleles from the individual's parents

Back

negative blood type

Front

- lack Rh antigens on red blood cells, so the white blood cells produce anti-Rh antibodies - cannot receive blood from a positive donor

Back

trisomy 21

Front

Down syndrome (least severe error in chromosome number, but still significant)

Back
