Patterns of Inheritance
Notes on Patterns of Inheritance:
Who's the Daddy??
Part 1:
Go to the Who's Your Daddy? Website, and do the Intermediate Solution. Solve (on your own paper) which baby belongs to which set of parents.
Part 2:
Design your own Who's the Daddy? game!
1) Draw a picture of a Baby with 2 of the characteristics from the following list:
3) Draw a picture of the baby’s Mother. Include the SAME 2 characteristics, and list Mom’s genotype and phenotype. The traits expressed don’t have to be the same as the baby, but make sure that genetically, it could be hers. (Meaning, if baby has two recessive genes, Mom has to have a recessive gene, too.)
4) Draw pictures of 3 possible Dads with the SAME 2 characteristics as Baby and Mom. List Dad’s genotype and phenotype under its picture. Make sure ONLY one Dad could genetically be the father. (Meaning, if baby has two recessive genes, Dad has to have a recessive gene, too.)
5) On a separate sheet of paper, do a total of 6 Punnett squares: two for each Dad - one for each characteristic, showing the possible babies to prove Who’s the Daddy!
6) Turn in! (Make sure it's readable...)
Rubric:
1 Baby with 2 traits
Trait 1: _____ / 2 points Trait 2: _____ / 2 points
1 Mom with same 2 traits
Trait 1: _____ / 2 points Trait 2: _____ / 2 points
3 Dads with same 2 traits
Dad 1: Trait 1: _____ / 2 points Trait 2: _____ / 2 points
Dad 2: Trait 1: _____ / 2 points Trait 2: _____ / 2 points
Dad 3: Trait 1: _____ / 2 points Trait 2: _____ / 2 points
Total __________/ 20 points
Correct genotypes with phenotypes:
Baby: Trait 1: _____ / 3 points Trait 2: _____ / 3 points
Mom: Trait 1: _____ / 3 points Trait 2: _____ / 3 points
Dad 1: Trait 1: _____ / 3 points Trait 2: _____ / 3 points
Dad 2: Trait 1: _____ / 3 points Trait 2: _____ / 3 points
Dad 3: Trait 1: _____ / 3 points Trait 2: _____ / 3 points
Total _________/ 30 points
Only one possible father? Yes _____ / 5 points
Total _________/ 5 points
6 Correct Punnett Squares:
Dad 1: Punnett Square 1: _____ / 8 points Punnett Square 2: _____ / 8 points
Dad 2: Punnett Square 1: _____ / 8 points Punnett Square 2: _____ / 8 points
Dad 3: Punnett Square 1: _____ / 8 points Punnett Square 2: _____ / 8 points
Total _________ / 48 points
Final Grade: _________
Part 1:
Go to the Who's Your Daddy? Website, and do the Intermediate Solution. Solve (on your own paper) which baby belongs to which set of parents.
Part 2:
Design your own Who's the Daddy? game!
1) Draw a picture of a Baby with 2 of the characteristics from the following list:
- Ear Lobes: Free (E), Attached (e)
- Widow’s Peak: Has peak (P), no peak (p)
- Freckles: has freckles (F), no freckles (f)
- Dimples: has dimples (D), no dimples (d)
- Chin: cleft chin (C), smooth chin (c)
3) Draw a picture of the baby’s Mother. Include the SAME 2 characteristics, and list Mom’s genotype and phenotype. The traits expressed don’t have to be the same as the baby, but make sure that genetically, it could be hers. (Meaning, if baby has two recessive genes, Mom has to have a recessive gene, too.)
4) Draw pictures of 3 possible Dads with the SAME 2 characteristics as Baby and Mom. List Dad’s genotype and phenotype under its picture. Make sure ONLY one Dad could genetically be the father. (Meaning, if baby has two recessive genes, Dad has to have a recessive gene, too.)
5) On a separate sheet of paper, do a total of 6 Punnett squares: two for each Dad - one for each characteristic, showing the possible babies to prove Who’s the Daddy!
