Pink eye is a recessive trait found in deer mice. In a cross between two individuals, both of whom are heterozygous for the pink

gladu [14]

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 = $\frac{(O - E)^2}{E}$ where O = observed frequency and E = expected frequency.

Phenotype Observed Expected Chi-square

Normal 18 3/4 x 20 = 15 $\frac{(18 - 15)^2}{15}$ = 0.6

Pink 2 1/4 x 20 = 5 $\frac{(2 - 5)^2}{5}$ = 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>

The cerebral cortex has a wrinkled appearance. the _____ lobe lies between the occipital lobe and the central_____.

Sergeeva-Olga [200]

The cerebral cortex appears to be wrinkly. Between the occipital lobe and the central sulcus is where the parietal lobe is located.

Where is the parietal lobe and what does it do?

One of the larger brain lobes, the parietal lobe is generally situated in the upper rear region of the skull. It interprets sensory data from the environment, primarily pertaining to touch, taste, and temperature. Damage to the parietal lobe may cause sensory impairment.

Where is the central sulcus ?
On the lateral and medial surfaces of the cerebral hemispheres, the central sulcus (also known as the Rolando's sulcus) divides the frontal and parietal lobes.

1. What would happen if the plasma membrane ruptured or breaks down?

ss7ja [257]

Answer:

( 1 ) If the plasma membrane ruptures or breaks down then the cell will not be able to exchange material from its surrounding by diffusion or osmosis. Thereafter the protoplasmic material will disappear and the cell will die.

( 2 ) If there is no Golgi apparatus in the cell , the plasma membrane would be affected because it needs to be able to grow larger for cell division. creation of lot of excess junk would occur in the cell. If this happened the cell would not able to live for long period.

A geneticist claims that four species of fruit flies should appear in the ratio

Gemiola [76]

There are sufficient evidences which are of 5% significance level to reject the claim.

<h3>What is chi-square test?</h3>

A statistical test used to compare observed results with expected results is referred to as the chi-square test.

According to the given scenario,

Ratio = 1:3:3:9
Sample size = 2000
Samples = 110, 345, 360, and 1185

To calculate:

Evidence to make conclusion to the geneticist's claim.

Total fruits = 1 + 3 + 3 + 9 = 16

As per the expected number of fruit flies

Each species = 1/16(2000) = 125.3/16(2000) = 375.3/16(2000) = 375.9/16(2000)

Each species = 1125

According to Chi-Square test -

$X^{2} =\epsilon\frac{(O_{i}-E_{i})^{2} }{E_{i}}$

$X^{2}$ = ( 110 - 125)²/125 + ( 345 - 375)²/375 + ( 360 - 375)²/375 + ( 1185 - 1125)²/1125

$X^{2}$ = (15)²/125 + (30)²/375 + (15)²/375 + (60)²/1125

$X^{2}$ = 8

with df = 4 - 1 = 3, and P( x² > 8) = 0.0460.

Thus, with a P-value, it is small, indicates 5% significance level to reject the claim.
