Leone Lattes devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.
An easy technique for identifying the blood type of a dried bloodstain was invented in 1915 by the Italian scientist Leone Lattes.
In 1939–1940, the Rh blood group system—which divides blood into groups depending on whether the Rh antigen is present or not—was created. Since then, more than a hundred various blood factors have been identified.
These characteristics can be utilized to pinpoint the particular groups to which possible suspects may belong because they show up unevenly in the population.
As different blood factors are identified in a sample, the proportion of individuals who have that particular combination of factors decreases and the sample becomes more unique.

Answer:
If an individual has a dominant phenotype it is not known what the exact genotype is. For example with the phenotype of brown eye color , the genotype could be heterozygous.
Explanation:
Dominant is a trait that shows dominance over a recessive trait. The dominant trait might have a heterozygous or homozygous genotype.
For example, if the brown eye is a dominant phenotype, it might be that a person might have a heterozygous genotype for this trait. One of the alleles might be the dominant one while the other allele might be recessive. In such a case, the effect of the recessive trait is masked by the dominant trait. Hence, the organism shows the dominant phenotype but has a heterozygous genotype.

Answer:
They can worsen symptoms for people with breathing difficulties.
Explanation:
Ultrafine particles are small particles found in dirty air. They aren’t filtered due to their very small size. They enter the lungs and cause certain conditions such as oxidative stress, inflammatory mediator release, and could induce heart disease, lung disease and other systemic effects.
People who have breathing difficulties have their case worsened due to these particles.
