21,22. The haploid genome size was estimated to be 4.83 Gb by flow cytometry, and heterozygosity was estimated at 1.28% viak-mer analysis (Supplementary Figs.1and2, Supplementary Table1). To assemble the genome, we generated a total of 409 Gb data on the Nanopore PromethION platform...
Any of the possible forms in which a gene for a specific trait can occur. In almost all animal cells, two alleles for each trait are inherited, one from each parent. Alleles on each of a pair of chromosomes are called homozygous if they are similar to each other and heterozygous if they...
The major histocompatibility complex (MHC) has become a paradigm for how selection can act to maintain adaptively important genetic diversity in natural populations. Here, we review the contribution of studies on the MHC in non-model species to our under
If a person inherits a different gene from one parent than the other for a trait, the person is said to be {eq}\rule{0.5in}{0.3pt} {/eq} for that trait. Crossing Over in Gametogenesis In the process of inheritance, the zygotes are...
Anthocyanins are well known for the colouring of flowers and other plant tissue. However, the evolution of these pigments might not only be due to the colour. It is possible that additional functions provided evolutionary advantages. A publication byLandi et al., 2015describes some of these funct...
TWEET:PavMYB10.1 is associated with the fruit skin colour of sweet cherry. Three different alleles lead to yellow to red colouration in the varieties 'Big Dragon', 'Rainier', and 'Lapins'. #MybMonday (6) Red and white strawberries
Morphological differences between species often in- volve changes at multiple genetic loci, as revealed by F2 quantitative trait locus (QTL) mapping (for example, Alpert et al., 1995; Orr, 2001; Gadau et al., 2002). A powerful approach to reducing this complexity is introgression of ...
Theory shows how sexual selection can exaggerate male traits beyond naturally selected optima and also how natural selection can ultimately halt trait elaboration. Empirical evidence supports this theory, but to our knowledge, there have been no experime
This type of trait has individuals that are homozygous for a particular trait. Genes, which are DNA segments, decide these characteristics.In a dihybrid cross, each phenotype is represented by a separate pair of alleles carried by the parents. The dominant allele is car...
