What are the conditions to cause water to diffuse out of a cell

Diffusion happens when there is a difference in concentration. So for water to diffuse out of the cell, the concentration of water has to be lower outside the cell, than inside the cell.

It depends on the DNA that is compared to another species to decide if the species are related or not. Like the human and the rhesus monkey they are very related because all of the genetic codes have the same DNA except for one.

Explanation:

q= 0.566

Homozygous individuals have two copies of the same allele for a gene. Homozygous dominant individuals carry two copies of the dominant allele, while homozygous recessive individuals carry two copies of the recessive allele.

Further Explanation:

DNA sets contain genes that may have different forms named alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new allles, impacting the resulting mRNA, and thus the encoded protein. Within species, there may be adaptation, along with genetic drift, preferential breeding, and natural selection.

Within a population certain alleles are fixed over time. In Hardy-Weinberg-allelic frequencies, the equilibrium for a particular gene is not undergoing evolution, being stable for several generations. Mutations, during this time affect the corresponding mRNA, and thus the encoded protein. Evolution may occur within populations, along with genetic drift, selective mating, and natural selection.

Over time, certain alleles become fixed within a population. Equilibrium for a specific gene is not undergoing evolution in Hardy-Weinberg-allelic frequencies are stable for several generations. During this period, mutations do not occur within the population, this is shown as

$p^{2} + 2pq +q^{2} = 1$ ....(eqn i)

where...

p represents the dominant allele frequency

q represents the frequency of the recessive allele

q^2 = the genotypic frequency of the homozygous recessive

p^2= the genotypic frequency of the homozygous dominant

2pq= frequency of the heterozygous genotype

and simply p+q= 1 ...(eqn ii)

The allelic freq. of r is denoted by q and the allelic frequency, R is denoted by p...

The total number of individuals= 32+ 68= 100

Thus q= √ $q^{2}$ = homozygous recessive individuals (white flowers)

Since there are 32 white flowering plants , freq rr= 32÷ 100= 0.32

...thus $q^{2}$ =0.32

and q= √ $q^{2}$ = √0.32= 0.566
