Probability and Genetics Genetic Reindeer

Probability Probability is the likelihood that a particular event will occur Whether a coin lands on heads or tails is probability

Genotypes/Phenotypes Genotypes are the genetic makeup, or set of genes, carried by an organism. They are shown by using upper and lowercase letters. (HH, Hh, hh) Phenotypes are the physical expression of the genes, such as blue eyes or tall plant.

Creating Genetic Reindeer The mother contributes HALF of the chromosomes to the baby in the egg, and the father contributes HALF of the chromosomes in the sperm. You will toss a PENNY to represent the mother’s chromosome and a NICKEL to represent the father’s chromosome.

Coin tossing If you toss the coin and get Heads, put a H in the box. If you toss the coin and get tails, put a h in the box. You toss ONE coin for the mom and ONE coin for the dad.

Genotype For genotype, you put the two tosses together. The possibilities will be HH, Hh, or hh HH and Hh will show the dominate phenotype, and hh will show the recessive phenotype.

Phenotype The phenotype will be found in the box under the data table.

Directions Toss the penny for the mom, and record H (Heads) or h (tails) in the box. Write them together under Genotype (HH, Hh, or hh) Use the chart to record the phenotype. For Sex of baby, you only flip the nickel. Mom’s can only give and x. Dad’s can give x or y. In this case, H is x and h is y.
