QuestionAnswer
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)
