Transcriptomic Analysis Reveals the Growth Regulatory Mechanisms in Diploid, Triploid, and Tetraploid Pacific Oyster (Crassostrea gigas)

Animals
Ploidy level exerts profound influences on the phenotypic and physiological traits of Crassostrea gigas. Compared to diploids, triploids exhibit desirable characteristics such as sterility, a faster growth rate, and improved meat quality.

Apomixis in Genista salzmannii DC. (Fabaceae) [PDF]

, 1991
Genista apomixis is described for the first time in two populations of Genista salzmannii DC.: the first is diploid and the second one tetraploid. There was no female meiosis and the megaspore mother cell functioned as an unreduced megaspore, which led ...

The "Dryopteris dilatata complex in Macaronesia and the Iberian Peninsula [PDF]

, 1983
Diploid and tetraploid species of the Dryopteris dilatata complex are found in Spain and Portugal. In an attempt to determine the relationships between species the cytology of both wild and synthetised hybrids has been investigated, and the results ...

Variation in nuclear genome size in a freshwater snail model system featuring a recent whole-genome duplication

Royal Society Open Science
Conspecifics often share—or are assumed to share—nuclear genome characteristics like nucleotide composition and genome size. These fundamental aspects of the nuclear genome can themselves be the object of natural selection. We here provide the first high-

De novo construction of polyploid linkage maps using discrete graphical models

, 2018
Linkage maps are used to identify the location of genes responsible for traits and diseases. New sequencing techniques have created opportunities to substantially increase the density of genetic markers.
