Predict the ratio of possible genotypes

Reference no: EM13887448

Stuck on this part of my bio lab. I'm not even sure where to start on this.

Yellow (Y) vs. Blue (y)
Green (G) vs. Red (g).

Part 3: Dihybrid Cross

Randomly (without looking) remove two beads from of Beaker 1 and two beads from Beaker 2. These four beads represent the genotype of Individual #1. Record this information in Table 3
Repeat Step 1 to obtain the genotype of Individual #2. Record the phenotypes of both individuals in Table 3.

Generation	Genotype of Individual 1	Genotype of Individual 2

P₁
P₂
P₃
P₄

Determine what the possible genotypes might be if each individual produced gametes. Record these possible genotypes in Table 4.
Predict the ratio of possible genotypes which could be produced by a cross between Individual #1 and Individual #2? Record your predictions in Table 4.Hint: Think back to the example the dihybrid cross in the Introduction. Record your prediction in Table 2.
Set up a Punnett square and determine the genotypes and phenotypes for this cross.
Repeat Step 5 four additional times (for a total of five subsequent generations).
