Resumen
La selección sexual no puede conducir a las diferencias de pigmentación abdominal de la mosca de la fruta. La discriminación de pareja observada en Drosophila podría deberse a variaciones de cepas experimentales, no a comportamientos naturales de elección de pareja.
Área de la Ciencia:
- Biología evolutiva Biología evolutiva.
- Genética La genética.
- Comportamiento animal Comportamiento animal.
Sus antecedentes:
- Las moscas de la fruta Drosophila exhiben una variada pigmentación abdominal, con algunas especies que muestran dimorfismo sexual y otras monomorfismo sexual.
- Se sabe que el gen bric-à-brac (bab) reprime la pigmentación específica masculina en las hembras de Drosophila melanogaster.
- Un estudio anterior sugirió que la selección sexual alteró la regulación del gen bab, lo que condujo al dicromatismo sexual en Drosophila.

01:20Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

02:27Background and Environment Affect Phenotype
5.9K
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...

02:45The Ratio of X Chromosome to Autosomes
11.6K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...
