Apply the product rule and sum rule appropriately when predicting the outcomes of genetic crosses.

State the MOST COMMON D positive genotype in both Fisher-Race and Wiener notations.

Consider the following cross involving three linked genes DeF/dEf x def/def. PHENOTYPES NUMBER OBSERVED DeF 76 def 30 dEf 82 DEF 24 Def 4 DEf 18 dEF 1 deF 15 The gene order is:

Please give the expected genotypic and phenotypic ratio of offspring from a cross between a person with Type AB blood and a person with Type O blood.

Enlist the step of controlled cross polination?

what is the true breeding means and what a test cross is?

Using the observed counts for each genotype, how do you find the expected values with those numbers and the frequencies?

Create a Punnett square and determine the genotypes and phenotypes for the resultant offspring in the following scenario: A brown cat (ww) is crossed to a cat with white hair (WW)

A homozygous purple plant is crossed with a homozygous white plant. Write the cross and offspring in a Punnet square. What is the genotype of phenotype ratios of the first generation (F1)? Gametes:               Genotypes: Phenotypes:

Define and design a test-cross.
