"ancestral descent" is a correct phrase that can be used in written English.
For example, you could say: "My family can trace our ancestral descent back to Scotland."
Alternatively, according to the phylogenetic approach to species (e.g. Cracraft 1983), species are classified according to common ancestral descent.
Such tribes and their nested groups (segments, co-liable groups and extended families, see Marx 1967; Stewart 2012) can be defined, following Cribb (1991) and Gingrich (2001), as a group dominating a territory, maintaining sociopolitical collective identity in which common ancestral descent distinguishes between its members and nonmembers.
However, an alarming 46% of women of mixed ancestral descent smoke and continue to smoke throughout pregnancy (5).
Identification of Hispanic subgroups by country of ancestral descent is unavailable via BRFSS, but, 63 % of Hispanics nationwide identify as of Mexican descent [ 10].

The same pathologists examined prostates obtained from 1,056 men and, despite men of African descent having a 60%% higher incidence of clinical prostate cancer and 2- to 3-fold higher mortality, the rates of latent cancers detected at autopsy were identical irrespective of ancestral descent [ 71].
In some instances it may be possible to assign some edges as representative of ancestral vertical descent by genetic inheritance and other edges as reticulations due to horizontal genetic transfers.
First, the variant SNP allele could represent the ancestral state by descent.
Orthologs evolve from a common ancestral gene via vertical descent (speciation), while paralogs evolve by duplication events taking place after speciation [ 1].
Some loci are ubiquitous and, after an ancient origin through transposition, originated through descent from the ancestral trypanosomatid.
Therefore we conclude that ACRATA domain is a heme binding 6TM domain that originated before the onset of eukaryotes (ancestral, YedZ), transmitted by vertical descent in a conventional manner (Nox family), and further expanded in vertebrates (STEAP family) (Fig. 4).
