Answer:
It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.
Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.
The answer is single nucleotide polymorphisms (SNPs)
It checks for variation in nucleotide sequences in particular genes that may be different among people, especially in different races. An example is a gene for melanin that would determine the trait for skin color. Single nucleotide changes in the gene between population can be used to differentiate populations.
The difference between science and pseudoscience is that science has actual research and evidence to back up the claim where pseudo science has no evidence. a similarity is that they both answer a question.
Answer:
Explanation:
Genes with recombination frequencies(RF) of 50 assort independently and are not genetically links together but gene that have less than 50 RF are genetically linked.
The Linked genes included
a-d 12 c-e 26
a-g 4 d-g 8
b-c 10
b-e 18
Starting the order from the most tightly linked to the least
a-g 4, genetic distance is 4cM
d-g 8 genetic distance is 8cM
b-c 10 genetic distance is 10cM
a-d 12 genetic distance is 12cM
b-e 18 genetic distance is 18cM
c-e 26 genetic distance is 26cM
