ake two coins and assume that heads represent the dominant allele (A) and tails represents the recessive allele (a). The genotype for each coin is heterozygous (Aa)
1. Take two coins and assume that heads represent the dominant
allele (A) and tails represents the recessive allele (a). The genotype for each coin is
heterozygous (Aa).
2. Assume that each coin represents one parent. When a single coin is flipped, one gamete
is formed (through the process of meiosis). If the flipped coin is on heads, then the
gamete has the dominant allele (A). When both coins are flipped simultaneously, there
will be two possible gametes that can combine through fertilization to form a zygote. Each
time you flip both coins, you will record the “genotype” of the offspring.
3. Flip the coins 100 times and record your results in the chart below
4. Interpret the data in your table
