Positive feedback is a control system that sends a signal to ( increase) a response.
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.
1) Some alleles are dominant and some are recessive. Principle of Dominance.
2) Genes passed down from parent to offspring. ...
3) During the production of gametes, two copies of each hereditary factor separate.
4) Genes for different traits can segregate independently during the formation of gametes.
Hope this helps! :)
The answer is Vestigal. It is a type of anatomical structure that no longer serves any function.
