the answer to this question is false
Answer:
c
Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square =
where O = observed frequency and E = expected frequency
Chamber O E Chi-square
A 18 10
= 6.4
B 2 10
= 6.4
<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8
<em>Degree of freedom</em> = 2 - 1 = 1
<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
<em>The correct option is </em><em>c</em><em>.</em>
They are all live organisms
Answer:
Brown eyes = 0.5
Blue eyes = 0.5
Explanation:
Given, B ( brown eyes ) is dominant over b ( blue/light eyes ). So,
BB = Brown
Bb = Brown
bb = blue/light
Mr. O'Ryan = blue eyes = bb
Mrs. O'Ryan = heterozygous brown eyes = Bb
Their children: Bb X bb :
B b
b Bb bb
b Bb bb
Half of the children will have Bb genotype and brown eyes, other half will have bb genotype and blue eyes. Hence, Kellan O'Ryan has 0.5 probability of blue eyes and 0.5 probability of brown eyes.
