This helpful video explains how to set up a dihybrid cross (a cross with two traits). Use the easy "cross-over" method that I explain in this video to set up a Punnett very easily!

Im having so much trouble still. How do I solve something like BcCe x BcCC with punnet square?? I am looking everywhere
@Bio_Tube Жыл бұрын
Are you sure you typed the genotypes correctly? BcCe is not a dihydrid cross. The "B" has to be matched with another "B", either B or b. Same with C. So doublecheck if you read the question correctly.

doesn't the dominant trait represented by the capital letter always comes first?
@Bio_Tube4 жыл бұрын
Writing the capital letter first is just a preference, it makes no difference in the expression pattern whether you write Dd or dD.

Pls make a punnett square for this question also 🙏 A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers. The progeny all bore violet flowers, but almost half of them were short. This suggests that the genetic make-up of the tall parent can be depicted as (a) TTWW (b) TTww (c) TtWW (d) TtWw
