a) Convert the expected phenotype ratio into the expected probability for each of the four phenotypes and record them in the table below. (the answer  as a value should be  between 0 and 1 rounded and to two decimal places.)

b)   Data set 1 and 2 are the actual data observed from the cross. Calculate the observed probability of the four possible phenotypes for each data set by dividing the number of progeny in each class by the total number of progeny and record these in the table below. (the answer  as a value should be  between 0 and 1 rounded and to two decimal places.)

2,A species of corn has three colours. Corn may be yellow, white or cream coloured. The cream colour is a mix of the yellow and white colours. 

Yellow and white corn are both homozygous while cream-coloured corn are heterozygous. 

1. What is one Punnett square to find out the percent probability of producing cream coloured corn from a cross between yellow and white corn. Describe the resulting offspring from the parental cross.

2. Identify the inheritance pattern that creates the cream colour.( Explaintion is needed for this )

3.

A)

i )the purpose of a test cross and describe the other individual involved in the cross

ii) what Punnett square could be made for each test cross possibility. 

B) a summary sentence explaining the result of each test cross

In pea plants, a round seed shape (R) is dominant over a wrinkled seed shape (r). A round-seeded pea plant was crossed with another round-seeded pea plant. What are the genotype(s) and phenotype(s) ratios of the F1 generation? 

what are all possibilities using Punnett squares. State the F1 generation genotypes and phenotypes.
