What is a Species?

What is a Species?

Formation of Species

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Asexual Reproduction

Asexual Reproduction

Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Complementation Tests

Complementation Tests

A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Summary

This summary is machine-generated.

Parthenogenesis, or asexual reproduction, was observed in female Komodo dragons. This reproductive plasticity allows them to switch between asexual and sexual reproduction, impacting conservation breeding strategies.

Herpetology
Reproductive Biology
Evolutionary Biology

Background:

Parthenogenesis is rare in vertebrates, with most species relying on sexual reproduction.
The Komodo dragon (Varanus komodoensis) is a large lizard species facing conservation challenges.

Purpose of the Study:

To investigate the occurrence of parthenogenesis in Komodo dragons.
To understand the reproductive plasticity of female Komodo dragons.

Main Methods:

Genetic fingerprinting was employed to identify offspring.
Reproductive histories of female Komodo dragons isolated from males were analyzed.

Main Results:

Parthenogenetic offspring were identified in two female Komodo dragons.
One female Komodo dragon later reproduced sexually, demonstrating a switch in reproductive strategy.

Conclusions:

Female Komodo dragons exhibit reproductive plasticity, capable of both asexual and sexual reproduction.
This finding has significant implications for captive breeding programs and the genetic diversity of threatened Komodo dragon populations.
