Exam 3 Vocabulary Inbreeding – involves mating between relatives who are biologically related to each other DNA fingerprinting - DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. If the two DNA profiles are a match, then the evidence came from that suspect. Conversely, if the two DNA profiles do not match, then the evidence cannot have come from the suspect. DNA fingerprinting is also used to establish paternity. Consanguinity - literally means with blood, but it’s also the genetic relatedness between individuals descended from at least one common ancestor Artificial insemination by donor - Introduction of semen into part of the female reproductive tract (as the cervical opening, uterus, or fallopian tube) by other than natural means. Coefficient of inbreeding - (F) measures probability of identity by descent In vitro fertilization - (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in a petri dish. IVF is a major treatment in infertility when other methods of assisted reproductive technology have failed. Mutagen - a chemical or physical phenomenon, such as ionizing radiation, that promotes errors in DNA replication. Exposure to a mutagen can produce DNA mutations that cause or contribute to diseases such as cancer. Surrogate mother - a method of reproduction whereby a woman agrees to become pregnant and deliver a child for a contracted party Ionizing radiation - Direct hit on DNA by high energy radiation may lead to ionized parts not rejoining correctly, can also cause indirect DNA damage Cell cycle - A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.
