| Question | Answer |
|---|---|
| immunohematology | (blank) |
| blood groups genetics | (blank) |
| genes | (blank) |
| codominant | (blank) |
| dominant | (blank) |
| recessive | (blank) |
| if both parents have same gene the antigen will be present in offspring | (blank) |
| some traits are inherited over generations and some traits are dominant over other traits ...termed recessive | (blank) |
| genes are carried on substances called chromosomes | (blank) |
| what are chromosomes? | (blank) |
| humans have 23 pairs of chromosomes | (blank) |
| 1/2 of the 23 chromosomes are inherited from one parent--other half is form other parent | (blank) |
| 22 pairs of chromosomes are referred as automsomes while the final pair is sex chromosomes | (blank) |
| what are autosomes ? | (blank) |
| chromsomes are made of dna | (blank) |
| Dna = Deoxyribonucleic acid | (blank) |
| The Dna within the genes that code that make each human being special /unique | (blank) |
| a Gene is located at a specific place on a chromosome called locus (plural : loci) | (blank) |
| each loci, may be various forms of the same gene called alleles | (blank) |
| define alleles | (blank) |
| K-gene is 99 % common among all white persons | (blank) |
| J-gene is very rare in whites | (blank) |
| J -gene is found in 20 % of african americans | (blank) |
| gene linkage : when 2 genes are located close on a chromsome they tend to travel together | (blank) |
| gene linkage describes 2 genes that are inherited together (example: C & D genes in the Rh System | (blank) |
| homozygosity = is when both chromosomes of a pair have the same identical gene | (blank) |
| homozygosity = if both chromosomes of a pair number one have the "E" gene, the person is considered " homozygous" for this gene | (blank) |
| heterozygosity = means when 1 chromosome of a pair carries 1 allele the other is a different allele. (example: one gene is ' E ' ..while other gene is ' e ' the person is considered heterozygous for E and e | (blank) |
| heterozygous person has e and E so both E & e antigens are expressed on the red cell surface. | (blank) |
| genes expressed on chromosomes = called genotype. | (blank) |
| Genotype = when a discussion is eveolved around chromosomes | (blank) |
| The Technician rarely knows an persons genotype | (blank) |
| The antigens that can be serologically detected on blood specimen being tested is called a persons phenotype | (blank) |
| Phenotype = is when antigens are detected by a technician from serological tests of a blood specimen. | (blank) |
| when a blood sample is typed " A + " the technician is reporting a phenotype of "A" antigen and a "D" Antigen ("positive") on a red cells | (blank) |
| Geneticians = | (blank) |
| antibodies = classified as globulins | (blank) |
| globulins are found in the blood plasma as well as many bodily fluids ( tears, saliva, breast milk ) | (blank) |
| glycoproteins = immunoglobulin molecules ( like : IgM, IgG, IgA, IgD, and IgE). | (blank) |
| Antibodies response to antigens. | (blank) |
| B - Cells, produced in the Bone marrow..create antibodies to attack foregin antigens | (blank) |
| Blood group A | has antibodies called Anti-B |
| Blood group B | has antibodies called Anti-A |
| Blood group AB | No antibodies |
| Blood group O | has A , B , and A,B antibodies |
| Blood type A | Acetygaltosamine & fucose sugars present |
| Blood type B | Galactose & fucose sugars present |
| Blood type O | Fucose sugars |
| Blood type AB | has all ( acetylgalactosamine + fucose + Galactose + fucose sugars) |
| IgM molecule is too small to bridge red cells | (blank) |
| IgG --are large enough to bridge between red cells | (blank) |
