Gregor Mendel “The Father of Genetics”
Gregor Mendel’s Peas Gregor Mendel studied pea plant phenotypes
Gregor Mendel’s Peas Mendel cross pollinated his pea plants and observed the “offspring”
Codominance Codominant alleles express the phenotypes associated with both alleles in a heterozygote. PP PW WW
Blood Types Before the 1900 s, blood transfusions were very risky. The ABO blood groups were discovered in 1900 by Karl Landsteiner.
Blood Types Before the 1900 s, blood transfusions were very risky. The ABO blood groups were discovered in 1900 by Karl Landsteiner. Four blood types: A, B, AB, and O Blood type is an inherited trait.
Blood types are named for molecules (antigens) on red blood cells. Type A Type B Type AB Type O
Blood types are named for molecules (antigens) on red blood cells. Blood types are an example of codominance. Type A Type B Type AB Type O
Alleles for blood type: I A, I B, i
Blood Type Punnett Square A Punnett square for the offspring produced by a type “O” father and an a Type “AB” mother
Blood Type Punnett Square A Punnett square for the offspring produced by a type “O” father and an a Type “AB” mother. i i IA I Ai IB I Bi
Type A Type B Type AB Type O
Type A Type B Type AB Type O
We produce antibodies against antigens that we do not have. Type A Type B Type AB Type O
Blood Type Lab Objective: Use your knowledge of blood types and genetics to determine if babies in a hospital were switched at birth.
Rhesus (D) Factor
Rhesus (D) Factor A person can have D antigens on their blood cells (and be positive) or no D antigens (and be negative).
Rhesus (D) Factor A person can have D antigens on their blood cells (and be positive) or no D antigens (and be negative).
Rhesus (D) Factor A person can have D antigens on their blood cells (and be positive) or no D antigens (and be negative). Alleles for Rhesus (D) Factor: + and + is dominant, - is recessive
