This is actually not a question. You are going to have to re-read it. If you are asking it as a question it will look like this: "When a rigid body rotates about a fixed axis, do all the points in the body have the same angular acceleration?"

In clover plants, the pattern on the leaves is determined by a single gene with multiple alleles that are related in a dominance

igomit [66]

Answer:

The correct answer is -

a. 7

b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc

c. p7 is abundant

Explanation:

According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance

let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :

p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7

p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6

p5p5, p5p4, p5p3, p5p2, p5p1 - 5

p4p4, p4p3, p4p2, p4p1 - 4

p3p3, p3p2, p3p1 - 3

p2p2, p2p1 - 2

p1p1- 1 least dominant

Thus, there are 28 different combinations or patterns of genotypes. 7 phenotypes patterns.

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge

Sophie [7]

Answer:

a. purple allele (C) = 0.609, pink allele (c) = 0.391

b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476

Explanation:

Given -

Purple flowers - 847

Pink flowers - 153

The frequency of recessive genotype i.e

$q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\$

Frequency of recessive allele i.e q is equal to

$q = \sqrt{0.153} \\q = 0.391$

As per hardy Weinberg's first equilibrium equation -

$p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609$

Frequency of purple homozygous species

$= p^2\\= 0.609^2\\= 0.371$

Number of purple homozygous species $= 0.371 * 1000= 371$

Number of pink homozygous species $= 0.153 * 1000= 153$

Heterozygous species is equal to

$(1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476$

What is the maximal interval for pausing chest compressions?

shusha [124]

When an advanced airway is in place, it may be reasonable for a rescuer to deliver 1 breath every 6 seconds<span> during continuous chest compressions. It may be reasonable to immediately resume chest compressions after shock delivery without a pause for a rhythm check.</span>
