Answer:
See the answer below
Explanation:
<em>If pink eye is recessive, it means that the normal eye is the dominant trait. According to Mendelian law, the ratio of normal to pink eye in a cross involving two heterozygous mice should be 3:1</em>.
Chi-square =
where O = observed frequency and E = expected frequency.
Phenotype Observed Expected Chi-square
Normal 18 3/4 x 20 = 15
= 0.6
Pink 2 1/4 x 20 = 5
= 1.8
Total Chi-square = 0.6 + 1.8 = 2.4
Degree of freedom = 2 - 1 = 1
Critical Chi-square value at 95% = 3.841
<em>The critical Chi-square value is more than the calculated value. </em><u><em>Hence, the observed number of offspring fits the expected number of offspring.</em></u>
