The frequencies of R is 0.75 and the frequencies for R' is 0.25.

Explanation:

Data given:

Genotype frequency of incomplete dominance on flower colour of snapdragon:

RR = red 0.5625

RR' = Pink 0.375

R'R' = 0.0625

frequency of R and R'=?

According to Hardy-Weinberg equilibrium the genetic variation in  a given population is constant from one generation to other if no factors causing evolution or genetic drift is there. So,

p^{2} + q^{2}+ 2pq = 1

The p represents = homozygous dominant  RR

q represents = homozygous recessive   R'R'

2pq = frequency of heterpzygous genotype RR'

p^{2} = 0.5625

p = 0.75   (frequency of R)

q^{2} = 0.0625

q = 0.25  (Frequency of R')

Their sum is 1 as according to Hardy Weinberg condition:

p+q = 1

Yanka [14]

A polysaccharide called starch consists entirely of glucose molecules. during early stages of starch digestion, starch would be broken down into<u> Maltose </u>

<u>Explanation: </u>

The start of the digestion happens in the mouth which is the first organ of the digestive system; the mouth contains salivary amylase that is present in the saliva.

<u>The complete hydrolysis of starch yields, in successive stages, glucose: </u>

<em>starch → dextrins → maltose → glucose </em>

This amylase breaks down starch into several units of Maltose and sends it to the next organ. This partially digested starch is completely digested into several glucose molecules in the intestine by various enzymes.

Maltose or malt sugar, is a disaccharide comprised of two glucose molecules. The most well-known disaccharide is sucrose, which is made of glucose and fructose.

Question 32
valkas [14]

The daughter cells produced from Meiosis are genetically different from each other due to the process of Crossing Over in the stage of Prophase I.


In Mitosis, there is no Crossing Over involved, since it is intended to help the body in growth and repair, not in reproduction.


Genetic Variation is important for reproduction so that not all offspring look exactly like each other or so that they do not look exactly like their parents.
