The DNA in the genome is divided among discrete chromosomes. The number of chromosomes in a somatic cell of a higher plant is referred to as the diploid number and is written as ‘2n,’ with one complete set (of n chromosomes) being inherited from each parent in sexual species. Chromosome...
Answer to: Fill in the chart below with the number of chromosomes, homologous chromosomes, and chromatids for each phase of meiosis. By signing up,...
Male heterogamety (XY or X0, if sex chromosomes are present) is the commonest sex determination in insects10, currently documented in 77% of species investigated4. The Colorado potato beetle (CPB—Leptinotarsa decemlineataSay, 1824) studied here, is one of the most successful globally invasive...
Mechanisms that lead to UPD include trisomy rescue, gamete complementation, monosomy rescue and somatic recombination. Most of these mechanisms can involve aberrant chromosomes, particularly isochromosomes and Robertsonian translocations. In the last decade, the number of UPD cases reported in the ...
Cucumber, Cucumis sativus is an important vegetable crop, and gynoecy has played a critical role in yield increase of hybrid cucumber production. Cucumber has a unique genetic system for gynoecious sex expression, which is determined by the copy number variation (CNV)-based, dominant, and dosage...
A comparison of loci associated with follicle number and menopausal age indicates that several variants were clustered in specific genomic regions on chromosomes 20, 13, and 12 (Online Resource Figure 3). The variants on chromosome 20 including one associated with follicle number in Caucasians (rs17...
