zygosity

 [zi-gos´ĭ-te]
the condition relating to conjugation, or to the zygote, such as (a) the state of a cell or individual in regard to the alleles determining a specific character, whether identical (homozygosity) or different (heterozygosity); or (b) in the case of twins, whether developing from one zygote (monozygotic twins) or two zygotes (dizygotic twins).

zy·gos·i·ty

(zī-gos'i-tē),
The nature of the zygotes from which individuals are derived; for example, whether by separation of the division of one zygote (monozygotic), in which case they will be genetically identical, or from two separate zygotes (dizygotic).

zygosity

/zy·gos·i·ty/ (zi-gos´ĭ-te) the condition relating to conjugation, or to the zygote, as (a) the state of a cell or individual in regard to the alleles determining a specific character, whether identical (homozygosity) or different (heterozygosity); or (b) in the case of twins, whether developing from one zygote (monozygosity) or two (dizygosity).

zygosity

(zī-gŏs′ĭ-tē)
n.
The genetic condition of a zygote, especially with respect to its being a homozygote or a heterozygote.

zygosity

[zīgos′itē]
the characteristics or conditions of a zygote. The form occurs primarily as a suffix denoting genetic makeup, referring specifically to whether the paired alleles determining a particular trait are identical (homozygosity) or different (heterozygosity) or to the condition in twins of having developed from the fertilization of one ovum (monozygosity) or two (dizygosity).

zy·gos·i·ty

(zī-gos'i-tē)
The nature of the zygotes from which twins are derived; e.g., whether by division of one zygote (monozygotic), in which case they will be genetically identical, or from two zygotes, in which case they will be genetically different.

zy·gos·i·ty

(zī-gos'i-tē)
Nature of the zygotes from which individuals are derived; e.g., whether by separation of the division of one zygote, in which case they will be genetically identical, or from two separate zygotes.

zygosity

the condition relating to conjugation, or to the zygote, as (1) the state of a cell or individual in regard to the alleles determining a specific character, whether identical (homozygosity) or different (heterozygosity); or (2) in the case of twins, whether developing from one zygote (monozygosity) or two (dizygosity).

A genetic split occurred between Indian cattle and those in Africa and Europe between 117,000 and 275,000 years ago, according to a calculation based on differences in mitochondrial DNA across cattle populations.
Still, Nei suspects that the genetic split of Africans and non-Africans dates to around 115,000 years ago if, as he suggests, an average of only 20 years separated succeeding prehistoric generations.
