Answer:
Allele pairs will separate when gamate are formed.
Explanation:
The law of Segregation states that "Organisms characteristics are determined by genes which occur in pairs;and that when gamates are produced,the paired genes separate (segregate) and are distributed as units to each gamate".
PCR, polymerase chain reaction, is the fastest way to artificially (in a laboratory) multiply few copies of DNA into many, in order to create enough of a sample to use for other genetic testing.
It is used quite often in forensic science, such as magnifying a small recovered sample of DNA from body fluids or tissue samples at a crime scene, into a vastly greater quantity of DNA for identification of suspect(s) or victim(s).
Answer:
The correct answer is option A: "The desert was once a vast ocean".
Explanation:
One of the most prominent fish fossils that were found in the arid deserts of western Egypt belong to the Giant Catfish named <em>Qarmoutus hitanensis</em>, that lived roughly 37 million years ago as it was scientifically determined. The presence of this and other related fossils indicate that the desert was once a vast ocean. Actually, the arid landscape of this zone has been named Wadi Al-Hitan (which means Valley of the Whales) in honor to its past.
