Q = recessive allele frequency = 0.3, and thus in H-W equilibrium there are ONLY two alleles, q (recessive) and
p (dominant). Therefore all of the p and q present for this gene in a population must account for 100% of this gene's alleles. And 100% = 1.00.
So p, the dominant allele frequency, must be equal to 1 - q --> p = 1 - q
p = 1 - 0.3 = 0.7.
Since heterozygotes are a combination of the p and q, we must again look at the frequencies of each genotype: p + q = 1, then (p+q)^2 = 1^2
So multiplying out (p+q)(p+q) = 1, we get: p^2+2pq+q^2 = 1 (all genotypes), where p^2 = frequency of homozygous dominant individuals, 2pq = frequency of heterozygous individuals, and q^2 = frequency of homozygous recessive individuals.
Therefore if the population is in H-W equilibrium, then the expected frequency of heterozygous individuals = 2pq = 2(0.7)(0.3)
2pq = 2(0.21) = 0.42, or 42% of the population.
Hope that helps you to understand how to solve population genetics problems!
This is because not all genes are expressed at the same time, so not all the proteins are present at a certain moment. The mechanisms that cell uses to control gene expression are called regulation of the gene expression. Thanks to regulation of the genes, cells have the ability to increase or decrease the production of specific gene products such as proteins. This property is important for the adaptability of an organism because it allows the cell to express protein when needed.
The condition is documented as jaundice.
<em>CORRECT STATEMENTS
> Water forms hydrogen bonds with other polar molecules. </em>
<em>> Water is a polar molecule. </em>
<em>> Water dissolves more ionic compounds.</em>
<em />Water is a polar molecule because of its uneven distribution of electron density. It is made up of two hydrogen atoms and one positive atom.
Since water is a polar molecule, it forms hydrogen bonds with other polar molecules. Though these bonds are relatively weak, however, there are so many of them present in water.
Water also dissolves most ionic compounds due to the fact that water is a universal solvent. When these compounds are added to water, there will be an interaction between the individual ions and the polar regions of the water molecules and disrupts the ionic bonds.
<em>INCORRECT </em>
> Liquid water is less dense than water vapor. - Liquid water has a higher density than water vapor. The fact that water vapor rises indicates that it is less dense than water.
>Water dissolves more hydrophobic substances. - Hydrophobic substances do not dissolve easily in water. It is termed as 'hydrophobic" because it means water-fearing.
I think the correct answer from the choices listed above is option A. The statement that describe the structure of each type of macromolecule would be that the <span>building blocks of carbohydrates are sugars that are made of carbon, hydrogen, and oxygen. Hope this answers the question. Have a nice day.</span>
