Create your own Dihybrid Cross. Just like last week, this will require you to give both an internet and written response.
ONLINE:
-Choose two traits to follow and give description of both traits (which is dominant/recessive, etc)
-Create a genetic cross for these 2 traits (dihybrid).
- Give phenotypic ratios that would result from your cross.
WRITTEN:
-Show your work: 16 box dihybrid punnett
I will be checking to make sure everyone has created a unique problem!
