"Recombination" means the formation of new genotypes by exchange of genetic material from two parents differing in two or more inheritable properties. In the genetics of higher organisms we differentiate between a) Recombination of "linked" genes, which lie on homologous chromosomes and can only be...
Linkagerefers to the tendency of genes that are located close to each other on the same chromosome to be inherited together. When two genes are linked, they do not assort independently during meiosis, the process of cell division that produces gametes. Instead, they tend to be passed down as...
Transduction: Transduction is the transfer of genes from one bacterium to other by a bacteriophage. Bacteriophage infects the bacterial cell and reproduces in them. When it does so, it may adopt either a lytic or alysogenic cycle[45]. If the bacteriophage adopts the lysogenic cycle then the ...
Sex-biased genes—genes that are differentially expressed within males and females— are nonrandomly distributed across animal genomes, with sex chromosomes and autosomes often carrying markedly different concentrations of male- and female-biased genes. These linkage patterns are often gene- and lineage-...
A set of co-inherited, physically linked genes often contributing to complex phenotypes. Heterochiasmy A variation in recombination rates and, accordingly, genetic map length between sexes. Heterogametic sex The sex in which the sex chromosomes differ. Structural variants Any variations in the struct...
These properties suggest that the three chromosomes replicate independently of one another. The two smaller chromosomes are devoid of known functional genes but nonetheless contain diagnostic mitochondrial features. Paired-end sequencing conflicts reveal differences in recombination dynamics among chromosomes, ...
Map distance is one of the key measures in genetics and indicates the expected number of crossovers between two loci. Map distance is estimated from the observed recombination frequency using mapping functions, the most widely used of those, Haldane and
Note that oligos migrate slightly more slowly on the gel than expected from their original sizes in vivo because of the addition of the labeled nucleotide and because of the remaining amino acid(s) left on each 5′ end after proteolysis of the covalently linked Spo11 protein (Neale et al.,...
