A teacher is explaining to her class the concepts of genetics regarding eye color.

She assumes that categories will have the following proportions: Blue = 20%, Green = 10%, Brown = 50%, Hazel = 20%

Use a 0.05 level of significance.

Here are the results for the class.

Observed Eye Colors: Blue=4; Green=3; Brown= 9, Hazel= 4,

What test are you running?

What are the observed values for the blue eye, brown eye, hazel eye color?

What are the expected values for the blue eye color, green eye color, brown eye color, and hazel eye color?

What are the degrees of freedom?

What is the null hypothesis?
What is the alternative hypothesis?

What is the test statistic? Use one decimal place.

What is the p-value? Use three decimal places.

What is your conclusion based on the p-value and the level of significance?

At the 5% significance level, what can you conclude?

Task- genetics The genes for body color (A), eye color (B) and wing length (C) are linked to the same autosomal chromosome of D. melanogaster, in the order of A - B - C. For body color, alleles encode 'A +' for wild type and 'a' for black body; for eye color, alleles encode 'B +' for wild type and 'b' for pink eyes; For wing length, alleles code 'C +' for wild type and 'c' for short wings. Wild-type...
