• Dihybrid Cross using Mendelian Genetics

  421149 Dihybrid crosses: Using the principles of Mendelian genetics, determine the genotypes and phenotypes of the resulting offspring from a parental dihybrid cross.

• Description of Mendelian Genetics

  The expected phenotypic ratio for a dihybrid cross = 9:3:3:1.

• Dihybrid Cross Genotype

  And a test cross is performed with one parent being always homozygous recessive for all the genes under consideration. Typically, a dihybrid testcross yields a 1:1:1:1 phenotypic and genotypic ratio among its progeny.

• Genetics and Gene Expression

  Please do the punnett square for a dihybrid cross and then work out the phenotypes. Since each parent is BbFf (it's a dihybrid cross), the possible gametes for each parent are BF, Bf, bF, and bf.

• Punnett Square

  true dihybrid cross, and for this you will always get a 9:3:3:1 phenotypic ratio (9 White, disk-shaped; 3 White and round; 3 Yellow and Disk; and 1 yellow and round) The genotypic ratio is as follows: WWDD: 1 WwDD: 2 wwDD: 1 WWDd: 2 wwDd: 2 WWdd
