If a population of 2000 individuals has 850 aa genotypes, 450 Aa genotypes, and 700 AA genotypes what is the allele frequency of the dominant allele (A)

What are the three types of counseling established by marine corps policy?

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.

Natural selection changes allele frequencies because some survive and reproduce more successfully than others.
