INCOMPLETE DOMINANCE INHERITANCE:
<span>5. In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage. These genes, however, show incomplete dominance. The heterozygous (BB') condition results in blue plumage. List the genotypic and phenotypic ratios expected from the following crosses: a) black x blue b) blue x blue c) blue x white</span>
<span>6. </span><span>In snapdragons, petal color is determined by a single gene locus with two alleles making the "red" allele (R) incompletely dominant to the "white" allele (r). Heterozygotes have petals, which are neither red nor white, but pink. a) If a true-breeding red flower is pollinated with pollen from a white flower: What fraction of the seeds (F1 generation) would be expected to produce red-flowered plants? What fraction of the gametes produced by the F1 plants would be expected to bear the R allele? b) If two pink flowered plants are crossed, what genotypic and phenotypic ratios are expected among the offspring (F1 generation)?</span>

The DNA of the samples is isolated, and then the mapping is carried out, which is done by equipment called "DNA Sequencers". With this, it is possible to compare the genomes and conclude to whom the hair belongs.
<h3>DNA in the hair?</h3>
In the case of hair, researchers can rely on these two types of DNA (nuclear and mitochondrial). However, according to the Easy-DNA Laboratory, a hair that is cut, unfortunately, does not contain any valid DNA nucleus. However, when the hair still contains the hair bulb (hair root) it is possible to extract the nuclear DNA, because in that region we have thousands of hair forming cells (keratinocytes).
With this information, we can conclude that the DNA can be analyzed and compared, arriving at who committed the bank robbery.

Cohesion causes water molecules to stick to each other. Cohesion is the attraction of like molecules
Answer AND Explanation:
Exponential phase is the phase during which growth is rapid. The growth rate is proportional to the amount of material or number of cells of the organism already present. This rapid growth is due to:
- An increase in number of cells dividing following a geometric progression.
- Cells having adjusted to the new environment.
- Food and other factors are not limiting hence cells are not competing for resources.
- The rate of cell increase being higher than the rate of cell death.
