Gametic phase
Gametic Phase
Gametic phase (/gəˈmɛtɪk feɪz/), also known as gametic linkage phase, is a term used in genetics to describe the statistical association, or linkage, between alleles at different loci that are transmitted together on the same gamete.
Etymology
The term "gametic phase" is derived from the words "gamete", which is a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote, and "phase", which in this context refers to a distinct period or stage in a process of change or forming part of something's development.
