Absolute Dating. The nuclear decay of radioactive isotopes is a process that behaves in a clock-like fashion and is thus a useful took for determining the absolute age of rocks. Radioactive decay is the process by which a "parent" isotope changes into a "Daughter" isotope.
Mutations. Definition. A Mutationoccurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed
A. metallic
I gotta use 20 characters so ignore this bucko
Answer:
A. transmission genetics
B. population genetics
C. molecular genetics
D. genomics
E. molecular genetics
Explanation:
Transmission genetics can be defined as the study of the mechanisms involved in the inheritance of genetic material by offspring from parents. This discipline started with the discovery of inherited characteristics in pea plants by Mendel (1865).
Population genetics is a subdiscipline of genetics that studies genetic variation within and between populations. Population genetics is an area that explains how allele and genotypic frequencies change across time, thereby this subdiscipline is closely linked to evolutionary biology.
Genomics is a broad area of genetics that studies the function, evolution, structure, function, mapping and comparison of genomes (i.e., the whole genetic material contained in each cell of a given organism). This discipline aims at understanding entire gene pools. Genomics includes different research areas including structural genomics, functional genomics, epigenomics and metagenomics.
Molecular genetics is a sub-discipline of genetics that studies the mechanisms involved in preserving the genetic material (i.e., DNA and RNA), and to understand how the structure and expression of the genetic material influence the observed variation among organisms.
D. It is type A because A is dominant and i is recessive.
