Chapter 11.2, Problem 3CC
Summary Introduction
To determine:
The fraction of off springs with a genotype consisting of at least two alleles in homozygous recessive state from the cross between PpYyIi and ppYyii.
Concept introduction:
A cross in which alleles for three characters are used is called a trihybrid cross. In a trihybrid cross, all the three laws of inheritance given by Mendel are followed which are: law of dominance, law of segregation and law of independent assortment.

What would this indicate? - Suppose you were to obtain a Chi-square value of 4.60 or lower in your data analysis (with 2 degrees of freedom). What would this indicate? - A heterozygous white-fruited squash plant is crossed with a yellow-fruited plant, yielding 200 seeds. Of these, 110 produce white-fruited plants while only 90 produce yellow-fruited plants. Are these results statistically significant? Explain using Chi-square analysis. - What if there were 2000 seeds and 1100 produced white-fruited plants & 900 yellow-fruited?arrow_forward
- Chi Squared Problems In the garden pea, yellow cotyledon color is dominant to green, and inflated pod shape is dominant to the constricted form. Considering both of these traits jointly in self-fertilized dihybrids, the progeny appeared in the following numbers: 193 green, inflated 184 yellow constricted 556 yellow, inflated 61 green, constricted Do these genes assort independently?
