) When predicting the phenotype of the offspring from a dihybrid cross, why is it so important that each gene is located in a di
Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.  

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic
kati45 [8]

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.
