Section 1: Translate the Genotype
“Translate” the following genotypes by working out what a dog with that genotype would look like. They start off easy, with just a few locii to work with, then they start to get harder!
Section 2: Predict the Litter
Using Punnet squares (just jot them down on a piece of paper if you like), work out the possible genotypes of the puppies produced from the following breedings.
1. Bb X bb
2. MM X Mm
3. Bb/Mm X bb/MM
4. AyAy/Bb/Mm X aa/Bb/Mm
5. kbrk/AyAy/Bb/Mm X kkbr/aa/Bb/Mm
6. kbrk/AyAy/Bb/Mm/sisi X kkbr/aa/Bb/Mm/siS
For Extra Marks
Work out what all those puppies would look like!
Section 3: Work out the Genotype
Work out the genotype of the dogs below using the format A locus/B locus/D locus/E locus/K locus/M locus/S locus/T locus. You can miss out the I, G and H locii (aren’t I kind?). If it’s impossible to tell which gene the dog has, or if it doesn’t matter what it is (e.g. if a dog has a copy of K, it doesn’t matter if it’s Kk or Kbr), just put a dash (-).
. . . Hang on, you thought I was going to give you the answers?
