Mendelian genetics: grass skirts
15 quick questions on AP Biology topic 5.3 Mendelian Genetics, each answered in a word or two. Print a sheet for each team, a key for the checker and a tick sheet, then tape the sheets to the board and race.
How it runs
- SnipA runner cuts one strip off the bottom of their team’s sheet.
- Answer as a pairBack at the table, they write the answer on the strip. No books.
- Get it checkedThe checker reads it against the key: you, or a student holding it.
- Back for the nextA tick earns the next strip. Wrong? Back to the table to try again.
The questions on this sheet
The checker’s key, with every answer, prints with the sheets.- Alternative version of a gene
- Allele combination, e.g. BB, Bb or bb
- Observable trait an organism shows
- Having two identical alleles for a gene
- Having two different alleles for a gene
- Allele shown in Aa; its partner is hidden
- Allele hidden in a heterozygote
- Grid that predicts offspring genotypes
- Family tree tracing a trait
- Each gamete gets one allele of a pair
- Aa × Aa, giving a 3:1 ratio
- AaBb × AaBb, giving 9:3:3:1
- Unknown × homozygous recessive
- Probability of A and B: multiply them
- Checks if observed data fit expected
