This two trait Punnett square will allow you to calculate both the phenotypic and genotypic ratio of the dihybrid cross It s also the perfect place to get some basic knowledge on the construction of genetic squares and learn some inheritance rules The genotype in each box is equally likely to be produced from a cross A two trait Punnett Square has 16 boxes The probability of a cross producing a genotype in any box is 1 in 16 If the same genotype is present in two boxes its probability of occurring doubles to 1 8 1 16

Mendel performed seven types of monohybrid crosses each involving contrasting traits for different characteristics Out of these crosses all of the F1 offspring had the phenotype of one parent and the F2 offspring had a 3 1 phenotypic ratio Reasoning about Gene Mapping Three Factor Cross The hypothetical study we just discussed is called a two factor cross because it focuses on two genes A two factor cross can tell us about the distance between two genes but cannot tell us anything about the order of the two genes
I Two factor cross two traits in one Punnett square You can use a model such as Punnett square to track the possible allele combinations offspring can have for two or more genes Since alleles for different genes are inherited independently from each other you need to account for many more possible allele combinations in the offspring This cross produces F1 heterozygotes with a yellow phenotype Punnett square analysis can be used to predict the genotypes of the F2 generation A self cross of one of the Yy heterozygous offspring can be represented in a 2 2 Punnett square because each parent can donate one of two different alleles

For example with two genes each having two alleles an individual has four alleles and these four alleles can occur in 16 different combinations This is illustrated for pea plants in Figure below In this cross known as a dihybrid cross both parents are heterozygous for pod color Gg and pod form Ff Punnett Square for Two Characteristics Cross a male that is heterozygous for both traits with a female that is heterozygous for both traits This is called a dihybrid cross This one will be one of the hardest crosses to accomplish correctly Problem 2 Walrus have tusks and that is what most of them have Walrus without tusks are very rare in the world
