Do female and male autosomal chromosomes have the same alleles? Do identical twins have genetic mutations? Does a somatic cell divide? Is gastrulation the same as the embryonic period? Homologous chromosomes se
Do autosomal cells have chromosomes? What are chromosomes? What are the 23 chromosomes? What are homologous chromosomes? Do female and male autosomal chromosomes have the same alleles? In what ways do human x and y chromosomes differ from one another?
All the children of a female thus have the same genome. In androgenesis (Verworn, 1891, Wilson, 1925), the development takes place only with the paternal chromosomes, after expulsion or destruction of the maternal chromosomes. Although rare, this phenomenon exists in nature in some animal ...
Sexual reproduction requires meiotic division, which emerged at the dawn of eukaryotic evolution (Barton and Charlesworth1998; Villeneuve and Hillers2001). To meet this requirement, most species rely on crossovers to segregate their homologous chromosomes and halve the chromosomes content creating sexual ...
Based upon homology, pD52 protein and each homologous protein or peptide may share at least some activity. A multiple sequence aligment is given in FIG. 2 with the protein of the invention being shown on line 4, in a ClustalW (1.7) analysis comparing the protein of the invention (line ...
Wheat Pina-D1a (DQ363911.1) and Pinb-D1a (DQ363913.1) alleles showed 95% and 93% homology with Sina and Sinb coding sequences of the tested triticale cultivar. Each ortholog contained several long, exceeding 21 nt 100% homologous fragments. This feature allowed us to apply the same, hpRNA...
BRCA1 and BRCA2 are tumour-suppressor genes encoding proteins that are essential for the repair of DNA double-strand breaks by homologous recombination (HR). Cells that lack either BRCA1 or BRCA2 repair these lesions by alternative, more error-prone mech
CHPT1 encodes cholinephosphotransferase [61], and SYCP3 encodes a component of the synaptonemal complex, which is involved in the pairing and crossover of homologous chromosomes during meiosis [62]. We found that the core region contained 50 linked SNPs in the same global frequency class as rs...
