Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans.here are two different forms of albinism: a partial lack of the melanin is known as hypomelanism, or hypomelanosis, and the total absence of melanin is known as amelanism or amelanosis.
The Photonâs Go-Splat World. The photon lives in a âgo-splatâ world. The clock of a photon completely stops the instant it is emitted and stays stopped throughout its journey. The distance traveled by a photon becomes zero as compared to the distance measured by the stationary observer.instein gave us some tools to work with to describe the various space-time relativistic changes as shown in Figure 1. There is a mass equation also, but the mass increase is not a factor here, since we know that the photon has no rest mass.
The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in genetics, which researchers use to date when two species diverged.It deduces elapsed time from the number of minor differences between their DNA sequences. It is sometimes called a gene clock.The notion of a molecular clock was first attributed to Emile Zuckerkandl and Linus Pauling who, in 1962, noticed that the quantity of amino acid differences in hemoglobin between lineages roughly matched the known evolutionary rate of divergence based upon fossil evidence.t is sometimes called a gene clock.
