Dihybrid Punnett Square Worksheet With Answers Set up a punnett square using the following information Dominate allele for black fur in guinea pigs B Recessive allele for white fur in guinea pigs b Dominate allele for rough fur in guinea pigs R Recessive allele for smooth fur in guinea pigs r Cross a heterozygous parent BbRr with a heterozygous parent BbRr 4
To predict the probability of these sorts of crosses we will make a dihybrid Punnett Square Activity 1 What are the phenotypes descriptions of rabbits that have the following genotypes Ggbb ggbb ggBB k es e J GgBb 2 A male rabbit with the genotype GGbb is crossed with a fe ale rabbit with the genotype ggBb The square is set up below Identify the combinations of alleles in the gametes Set up Punnett square to find the possible offspring of the cross Answer the question in the problem In guinea pigs black fur B is dominant to brown fur b Short hair S is dominant to long hair s

Worksheet Dihybrid Crosses STEP 1 Determine what kind of problem you are trying to solve STEP 2 Determine letters you will use to specify traits STEP 3 Determine parent s genotypes STEP 4 Make your punnett square and make gametes STEP 5 Complete cross and determine possible offspring STEP 6 Determine genotypic and phenotypic ratios To predict the probability of these sorts of crosses we will make a dihybrid Punnett Square 1 What are the phenotypes descriptions of rabbits that have the following genotypes 2 A male rabbit with the genotype GGbb is crossed with a female rabbit with the genotype ggBb The square is set up below
Dihybrid crosses involve tracking two traits simultaneously For example we can predict the outcome for offspring as the traits for both height and color are concerned Example 1 Dihybrid Cross In garden peas tallness T is dominant to shortness t and axillary flowers A are dominant to terminal flowers a STEP 1 Determine what kind of problem you are trying to solve STEP 2 Determine letters you will use to specify traits STEP 3 Determine parent s genotypes STEP 4 Make your punnett square and make gametes STEP 5 Complete cross and determine possible offspring STEP 6 Determine genotypic and phenotypic ratios

If we look at our Punnett square the only dihybrid genotype that is heterozygous for both traits is AaBb There is an 8 16 chance of offspring being awesome and bashful or heterozygous for both traits with the genotype AaBb 8 16 1 2 50 The correct answer is 50 Dihybrid Cross Worksheet 1 Set up a punnett square using the following information Dominate allele for tall plants D Recessive allele for dwarf plants d Dominate allele for purple flowers W Recessive allele for white flowers w Cross a homozygous dominate parent DDWW with a homozygous recessive parent ddww 2
