how would iset this up on a punnet square and solve it Title: how do i solve a trihybrid cross? Post by: JulianDavis on May 7, 2012 Don't use a huge Punnett square! Use a Branch diagram.
First, make three Punnett square for the individual traits: Aa x Aa = 1/4 AA 1/2 Aa 1/4 aa bb x bb = all bb CC x Cc = 1/2 CC and 1/2 Cc Second, branch diagram (remember all of the b's will be bb) AA bb CC (1/4 x 1 x 1/2 = 1/8) AA bb Cc (1/4 x 1 x 1/2 = 1/8) Aa bb CC (1/2 x 1 x 1/2 = 1/4) Aa bb Cc (1/2 x 1 x 1/2 = 1/4) aa bb CC (1/4 x 1 x 1/2 = 1/8) aa bb Cc (1/4 x 1 x 1/2 = 1/8) |
