Rabbit genetics problem for practice |
|||||||||
#1 Fill in the punnet square for a pair of New Zealand Whites that produce offspring with buck teeth. Use N to denote the normal version of this gene and n to denote the buck tooth version of this gene. NN = Normal teeth: non-carrier, Nn = Normal teeth: carrier, nn = Buck teeth. |
|||||||||
| If both parent appear normal but are carriers then: | |||||||||
| How many offspring will be normal (NN)?_____ | |||||||||
| How many offspring will have buck teeth (nn)?_____ | |||||||||
| How many offspring will be carriers like the parents (Nn)?_____ | |||||||||
#2 Fill the punnet square for a cross between a black Netherland Dwarf (genotype aaBBDDEE) and a blue Netherland Dwarf (Genotype: aaBBddEE) (Hint: Both are homozygous!) |
|||||||||
List the number of offspring with the following colors; BLACK(DD or Dd)_____, BLUE(dd)_____ |
|||||||||
Now if the black rabbit had a blue parent (like in the above problem) was crossed black to a blue rabbit, what would happen? |
|||||||||
List the number of offspring with the following colors; BLACK(DD or Dd)_____. BLUE(dd)_____ |
