Name: Background: Human Blood Trpe and inheritances tab Simulation Date: - Human blood type is a trait that follows the predictable patterns we find in traditional Mendelian genetics. - There are eight major Phenotypes typically found among humans, with eighteen typical Genotypes (see chart). - The Rh factor, the positive ( + ) or negative ( ) , follows traditional Dominant/recessive inheritance and expression. - Positive ( t ) is dominant. -Negative ( ) is recessive. - The Immunoglobulin ABO Genotypes follow Dominant/recessive inheritance, with two dominant alleles and one recessive allele. -Type A ( I A ) and Type B ( 1 B ) are dominant, but when both are present, both are expressed (Codominance) - Type O ( i ) is recessive Procedure: Each student will need this sheet, 4 plastic Easter eggs same color, scissors, pencil, and a partner. 1. Parent Assignment: Each student will be assigned a blood type with a specific genotype. 2. Melosis: In the spaces below, write the four possible allele combinations for gametes, based on that blood type. Carefully, cut out each individual square to form four separate genome squares (these are for the gametes). 3. Gametogenesis: Place each genome square inside a separate plastic egg. 4. Fertilization: Students are to randomly exchange one egg with their partner and randomly pair it with one of their own eggs. 5. Development of Offspring: Open the two eggs and write down the genomes from the paper squares in the spots indicated on the back of this sheet. This is the genotype of the new offspring. In the space indicated, write the Phenotype of the new offspring.

1. Name: Background: Human Blood Trpe and inheritances tab Simulation Date: - Human blood
type is a trait that follows the predictable patterns we find in traditional Mendelian genetics. -
There are eight major Phenotypes typically found among humans, with eighteen typical
Genotypes (see chart). - The Rh factor, the positive ( + ) or negative ( ) , follows traditional
Dominant/recessive inheritance and expression. - Positive ( t ) is dominant. -Negative ( ) is
recessive. - The Immunoglobulin ABO Genotypes follow Dominant/recessive inheritance, with
two dominant alleles and one recessive allele. -Type A ( I A ) and Type B ( 1 B ) are dominant,
but when both are present, both are expressed (Codominance) - Type O ( i ) is recessive
