How do blood Type B glycoprotein on blood cell ONLY
types work? Type
B
How do blood No recognizable glycoprotein from this group on blood cell
types work? O
How do blood Both A and B glycoproteins
types work? AB
- Are proteins
What are Glycoproteins? - If you don't normally have it and you get blood with it,
your body's own antibodies will attack it as foreign
Additional blood system describing many antigens on the blood
cells
Rh +/- Rh positive (Rh+):
Blood cells have
D antigen Rh
negative (Rh-):
Blood cells do not have D antigen

Mendel (1865): OG
Thomas Hunt Morgan: Added to Mendels idea w/
Founders of Linkage Chromosome Theory Morgan's Model organism
was the fruit fly
Drosophila melanogaster
- According to Mendel's law of independent
assortment, alleles for different characterisics
always assort independently (H0)
Linkage
-Morgan looked at two traits:
Body color (gray dominant) and wing shape (large wings
dominant)
- Morgan also discovered that even if genes are linked,
they are not always inherited together
Rare- genes at different loci on the same chromosome do
sometimes separate
Genetic Recombination: -Genes may recombine during prophase 1 of Meiosis by crossing
Absolute Linkage over.
-Chromosomes exchange corresponding segments.
The exchange involves two chromatids ir the
tetrad; both chromatids become recombinant
Same gene, just slightly different alleles
Melanocortin 1 receptor
(MC1R) gene Produces pheomelanin more than euomelanin
Recombinant offspring phenotypes (non-parental)
appear in recombinant frequencies: Divide # of
recombinant offspring by total # of offspring
Genetic Recombination
- Frequencies are greater for loci that are further apart
- Frequencies can be used in calculating genetic distance and
gene maps
- Genes on sex chromosomes don't follow Mendelian patterns
Sex Linkage
- Y chromosome carries few genes; the X chromosome carries
many
Hemizygous Males only have one copy of these genes

Character is controlled by loci on the sex chromosome
Sex-linked inheritance
Ex: Eye color in Drosophila
- Appear more often in males
- Daughters who are heterozygous are carriers
- Mutant phenotype can skip a generation if it passes from a male
X-linked recessive phenotypes to his daughter
- Requires two alleles to affect the female phenotype
-When said to express dominant inheritance, it means
that a single dose of the allele will affect the phenotype
of the female
- male w/ single recessive allele (X^aY) will be colorblind
- female w/ single recessive allele (X^A X^a) will be a carrier
Sex-linked Inheritance
- female w/ two recessive alleles (X^a X^a) will be colorblind
Example:
Color-blindness
-Chance of female receiving two recessive alleles is less
caused by recessive allele (a)
than the chance of a male receiving a single recessive
allele...therefore, males are more likely to be colorblind
Sex-linked Son will be normal
Inheritance Example: Daughters will be carriers
Mom is normal
(X^A X^A)
Dad has the allele (X^a Y)
What will the sons and
daughters be?
Sex-linked 50% chance sons will have
Inheritance Example: the disorder 50% chance
Mom is a carrier daughters will be carriers
(X^A X^a)
Dad is normal (X^A Y)
What will the sons and
daughters be?
Sex-linked 50% chance all offspring will have the disorder; regardless of sex
Inheritance Example:
Mom is a carrier
(X^A X^a)
Dad has the allele (X^a Y)
What will the sons and
daughters be?
