Genetics of Speciation02:16

Genetics of Speciation

21.7K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

What is Population Genetics?

64.8K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

How Data are Classified: Categorical Data

44.8K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

How Data are Classified: Numerical Data

38.1K
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.3K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Area of Science:

  • Forensic Science
  • Population Genetics
  • Genomics

Background:

  • Genome-wide data presents opportunities and challenges for forensic applications.
  • Existing statistical, computational, ethical, economic, and technical hurdles exist.
  • Current population genetics theory is inadequate for forensic use of genome-wide data.

Purpose of the Study:

  • To analyze the potential and difficulties of applying genome-wide data in forensics.
  • To highlight the insufficiency of current population genetics theory for forensic applications.
  • To propose a path forward for the reliable use of genetic evidence.

Main Methods:

  • Analysis of the current state of population genetics theory.
  • Evaluation of statistical, computational, ethical, economic, and technical challenges.
  • Review of existing approaches for genetic marker analysis.

Main Results:

  • Genome-wide data application in forensics is hindered by theoretical limitations in population genetics.
  • Experts cannot currently quantify the evidentiary value of genome-wide results.
  • Established methods using a limited number of validated genetic markers are preferable in the interim.

Conclusions:

  • Substantial theoretical framework improvements are needed for forensic genome-wide data analysis.
  • A generalized theoretical and biostatistical model is required for accurate quantification of evidence.
  • Whole genome population analyses can aid in selecting optimal genetic markers for forensic use.
