This point always has a lower heterozygosity (y value) than the corresponding (in allele frequency p) Hardy-Weinberg equilibrium. In population genetics, the Wahlund effect is a reduction of heterozygosity (that is when an organism has two different alleles at a locus) in a population caused by subpopulation structure.
An amoeba of the genus Mayorella (Amoebozoa, Discosea). Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm.
Difflugia is the largest genus of Arcellinida, one of several groups of Tubulinea within the eukaryote supergroup Amoebozoa. [1] Arcellinida species produce shells or tests from mineral particles or biogenic elements (e.g. diatom frustules) and are thus commonly referred to as testate amoebae or shelled amoebae.
The Hardy–Weinberg principle can also be used to estimate the frequency of carriers of an autosomal recessive condition in a population based on the frequency of suffers. Let us assume an estimated 1 2500 {\displaystyle \textstyle {\frac {1}{2500}}} babies are born with cystic fibrosis , this is about the frequency of homozygous individuals ...
Wilhelm Weinberg (25 December 1862 – 27 November 1937) was a German obstetrician-gynecologist, practicing in Stuttgart, who in a 1908 paper, published in German in Jahresheft des Vereins für vaterländische Naturkunde in Württemberg (The Annals of the Society of National Natural History in Württemberg), expressed the concept that would later come to be known as the Hardy–Weinberg principle.
Amoeba is a genus of single-celled amoeboids in the family Amoebidae. [2] The type species of the genus is Amoeba proteus , a common freshwater organism, widely studied in classrooms and laboratories.
Giant viruses, or nucleocytoplasmic large DNA viruses, frequently infect Amoebozoa and other protists causing amoeba lysis and cell rounding in 12 hours and amoeba population collapse in 55 hours. [3] As such, there is a strong selective pressure on both Amoebozoa and their symbionts to resist these viruses.
Chaos is a genus of single-celled amoeboid organisms in the family Amoebidae.The largest and most-known species, the so-called "giant amoeba" (Chaos carolinensis), can reach lengths up to 5 mm, although most specimens fall between 1 and 3 mm. [3] [4] [5]
