Addition (often signified by the plus symbol +) is one of the four elementary, mathematical operations of arithmetic, with the others being subtraction, multiplication and division. The addition of two whole numbers is the total amount of those quantities combined.hen addition is used together with other operations, the order of operations becomes important. In the standard order of operations, addition is a lower priority than exponentiation, nth roots, multiplication and division, but is given equal priority to subtraction.

It is inherited as an autosomal-recessive disorder and is characterized by a hypersensitivity of the skin to ultraviolet radiation, a deficiency in the repair of damaged DNA, and a resultant high incidence of skin cancers.
Chin fissure -- dominant, so expressed in heterozygous and homozygous dominant individuals -- 3/4 (or 75%) possible outcomes will have at least one dominant allele. -------------. 2. Albinism (lack of skin pigmentation) is caused by a recessive autosomal allele.A man and a woman, both normally pigmented, have an albino child. The mother is now pregnant again, and her doctor tells her she is carrying fraternal twins (resulting from two eggs between fertilized by separate sperm).r since one parent only have one possible gamete and the other only has two possible combinations, you can do a smaller punnett's square --. tp. TP. TtPp. Tp. Ttpp. ---------------------------. 5. Black fur in mice is dominant to brown fur (B â dominant allele, b-recessive allele).
