Across
- 2. carries instructions responsible for expression of traits; a pair of inherited genes controls a trait; one member of the pair comes from each parent; often called alleles
- 4. physical appearance of an organism (description of the letters)
- 6. graphic organizer to map genetic traits between generations
- 8. cross involving 2 traits
- 9. graphic organizer used to show the probable results of a genetic cross
- 11. two alleles of a pair are identical (BB or bb)
- 12. mating of an individual of unknown genotype with an individual of known genotype; can help to determine the unknown genotype of the parent
Down
- 1. cross involving one trait
- 2. genetic makeup of an organism (represented by the letters)
- 3. two alleles of a pair that are different (Bb); often called hybrid
- 5. controlling allele; designated with a capital letter (RR, Rr)
- 7. hidden allele; designated with lower case letters (rr)
