THE existence of sub-diploid chromosome numbers in the somatic tissues of mammals has for long been a matter of controversy. This had centred around several earlier reports of the normal occurrence of ...

A) In a normal meiosis, chromosomes align precisely at the recombination site and crossovers do not change the number of genes in the recombinant chromosomes. B) The presence of duplicated sequences ...

Developing elite fruit cultivars typically requires long breeding cycles, especially in perennial woody species. This study uncovers how sexual reproduction of a fertile triploid loquat generates a ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...
