(a)What is your null hypothesis?
(b)What is your expected phenotypic ratio based on Mendelian inheritance?
(c)Calculate the expected number of flowers you should have gotten based on the Mendelian inheritance. Then calculate a chi-square value, degrees of freedom, and a p-value.
- Chi-square statistic: _____
- Degrees of freedom (# phenotypes -1):
- P-value:
(d)Interpret your results. Do you reject it or fail to reject your null hypothesis (please restate the null)?
Answer:
(a)
(b)9:3:3:1
(c)
- Chi-square statistic: 3.8914
- Degrees of freedom (# phenotypes -1) =3
- P-value: 0.2734
(d)We fail to reject the null hypothesis.
Step-by-step explanation:
In the flowering plant, white flowers (B) are dominant over red flowers (b), and short plants (E) are dominant over tall flowers (e). An F2 generation was created by crossing two F1 individuals (each BbEe).
(a)The null hypothesis is:
(b)The gametes are BE, Be, bE and be.
The offsprings are presented in the table below:
The expected phenotypic ratio based on Mendelian inheritance
BE:Be:bE:be=9:3:3:1
(c)
Therefore:
- Chi-square statistic: 3.8914
- Degrees of freedom (# phenotypes -1): 4-1 =3
- P-value: 0.2734
(d) Our null hypothesis is:
Since p>0.05, the given data fit the predicted phenotypic ratio.
We, therefore, fail to reject the null hypothesis.
The difference in the observed and expected are sosmall that they can be attributed to random chance.
Answer:
Part 1) "a" value is
Part 2) The vertex is the point
Part 3) The equation of the axis of symmetry is
Part 4) The vertex is a minimum
Part 5) The quadratic equation in standard form is
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
if a > 0 then the parabola open upward (vertex is a minimum)
if a < 0 then the parabola open downward (vertex is a maximum)
The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex
so
In this problem we have
-----> this is the equation in vertex form of a vertical parabola
The value of
so
a>0 then the parabola open upward (vertex is a minimum)
The vertex is the point
so
The equation of the axis of symmetry is
The equation of a vertical parabola in standard form is equal to
Convert vertex form in standard form
see the attached figure to better understand the problem
