Engineered gene drives—the process of stimulating the biased inheritance of specific genes—
have the potential to enable the spread of desirable genes throughout wild populations or to …

B chromosomes are supernumerary chromosomes which are often preferentially inherited,
deviating from usual Mendelian segregation. The balance between the so-called …

Only female insects transmit diseases such as malaria, dengue and Zika; therefore, control
methods that bias the sex ratio of insect offspring have long been sought. Genetic elements …

Genetic elements compete for transmission through meiosis, when haploid gametes are
created from a diploid parent. Selfish elements can enhance their transmission through a …

Meiotic drive is the preferential transmission of a particular allele during sexual reproduction.
The phenomenon is observed as spore killing in multiple fungi. In natural populations of …

In some eukaryotes, germline soma differentiation involves elimination of parts of the
genome from somatic cells. The portions of the genome restricted to the germline often …

Insects play important roles as predators, prey, pollinators, recyclers, hosts, parasitoids, and
sources of economically important products. They can also destroy crops; wound animals; …

The rule of Mendelian inheritance is remarkably robust, but deviations from the equal
transmission of alternative alleles at a locus [aka transmission ratio distortion (TRD)] are also …

Sex chromosome meiotic drive, the non-Mendelian transmission of sex chromosomes, is the
expression of an intragenomic conflict that can have extreme evolutionary consequences …

Some genes or gene complexes are transmitted from parents to offspring at a greater-than-
Mendelian rate, and can spread and persist in populations even if they cause some harm to …
