Referring to the gametic cell lines (ova and spermatozoa and their precursors) that have the capacity to give rise to offspring.

Refers to the chromosome complement of sex cells (i.e. sperm or egg cells), which have only one copy of each chromosome, and therefore have half the number of chromosomes found in other cells of the ...

Haplotype

Biology; Genetics

A specific set of alleles that are physically located close to each other on the same chromosome and are commonly inherited together.

Heritability

Biology; Genetics

The proportion of phenotypic variation that is explained by genetic factors.

Heteroplasmy

Biology; Genetics

The occurrence in a single cell of more than one different population of mitochondrial DNA sequence.

Identity by descent

Biology; Genetics

Alleles are identical by descent if they can be traced back to a common ancestor. Identity by descent is a more stringent classification than identity by state. Identity by descent is the basis for ...
