Directions:
1. flip a coin two times for each trait investigated in the worksheet. if the coin lands on heads, record a capital letter; if the coin lands on tails, record a lowercase letter.
2. the capital letters will represent a dominant allele; the lowercase letters will represent a recessive allele.
3. check the genotype/phenotype key to determine what trait your individual will inherit.
we did the first one for you as an example. our student flipped the coin and it landed on tails; therefore, he recorded a lowercase “f” in the chart. on the next flip, the coin landed on heads; therefore, he recorded a capital “f” in the chart. when he consulted the genotype/ phenotype key, he found that freckles were a dominant trait, which means that the individual will have freckles.
continue flipping the coin to fill in the chart. when you have completed the chart, use the key to determine the phenotype of the individual. be careful not to miss the question at the end of the chart. when you are done, attach your chart to the assessment 5.06 genotypes and phenotypes.

trait flip the coin to determine what trait the child will receive from his or her mother flip the coin to determine what trait the child will receive from his or her father combine the letters placing the capital letter first consult the genotype/phenotype key and record what trait will be exhibited (the individual’s phenotype)
freckles, present or absent – use the letter f or f
f
f
ff
freckles present
widow’s peak, present or absent – use the letter w or w
earlobes, attached or detached – use the letter e or e
face shape, round or square – use the letter r or r
cleft chin, present or absent –use the letter c or c
bushy eyebrows or fine eyebrows – use the letter b or b

question: this activity describes the dominant and recessive pattern of inheritance. identify and describe two other patterns of inheritance listed in the lesson.
