Rock, Paper Scissor for a tie INTRODUCTION: If Mendel were given a mommy white horse & a daddy brown horse & asked what their offspring would look like, he would've said that a certain percent would be white & the others would be brown.  He would never have even considered that a white horse & a brown horse could produce a roan (a color that results when the horse has both brown and white hairs) horse!  For Mendel, the phenotype of the offspring from parents with different phenotypes always resembled the phenotype of at least one of the parents. Mendel was unaware of the phenomenon you will investigate at this station.

Create a Key for the alleles & their respective phenotype(s) What percent of kittens would have tan fur if a tabby cat is crossed with a black cat? Describe how this type of inheritance is SIMILAR to complete dominance explained by Gregor Mendel. A cross between a black cat & a tan cat produces a tabby pattern (black & tan fur together). Complete a punnett Square for the following problem and then answer the question: Describe how this type of inheritance is DIFFERENT from complete dominance explained by Gregor Mendel.

INTRODUCTION: If Mendel were given a mommy black mouse & a daddy white mouse & asked what their offspring would look like, he would've said that a certain percent would be black & the others would be white.  He would never have even considered that a white mouse & a black mouse could produce a GREY mouse!  For Mendel, the phenotype of the offspring from parents with different phenotypes always resembled the phenotype of at least one of the parents. Mendel was unaware of the phenomenon you will investigate at this station.

INTRODUCTION: In 1910 Morgan studied the Drosophila fly and found a mutant male fly, which expressed the trait of white eyes instead of the normal red eyes. This trait was very unusual in that species and Morgan wanted to see if the trait would be passed on to its offspring. He experimented to find if this strange trait would be inherited according to Mendel's research. First he crossed the mutant male fly with a normal female with red eyes, to observe whether the white or red eyes were dominant. The F1 generation all had red eyes, which made Morgan conclude that red eyes were dominant over white. He continued the steps of Mendel's experiment by crossing two flies from the F1 generation with each other. Out of 4252 flies in his F2 generation, 782 had white eyes but surprisingly all the flies with white eyes were also male. This strange observation puzzled Morgan to wonder why there weren't any females with white eyes. He then crossed flies from the F1 generation with the original male fly with white eyes. This cross resulted in white-eyed and red-eyed males and females, making a 1:1:1:1 ratio.

The tallest person in the group needs to read this. INTRODUCTION: If Mendel had a mother with type B blood and a father with type A blood, he would've said that a certain percent of their offspring would have type A blood and the rest of the offspring would have type B blood. He would never have even considered that a mother with type B blood and a father with type A blood would produce one child with type A blood, one child with type B blood, one child with type AB blood and another child with type O blood. Instead of a dominant and a recessive allele (two alleles), there are three alleles present for blood type (IA, IB and i). For Mendel, the phenotype of the offspring from parents with different phenotypes always resembled the phenotype of at least one of the parents. Mendel was unaware of the phenomenon you will investigate at this station.
