Y-5: A cusp pattern found in lower molars in which there are five main cusps separated by grooves, and the mesiolingual and distobuccal cusps touch.

Y chromosome: A sex chromosome that when present is found in one copy in the heterogametic sex, along with an X chromosome, and is not present in the homogametic sex. Not all organisms with sex chromosomes have a Y chromosome.

yeast artificial chromosome (YAC): A cloning vector in which DNA fragments several hundred kilobase pairs long can be cloned in yeast. A YAC is a linear vector with a yeast telomere at each end, a centromere, a sequence for autonomous replication in yeast, a selectable marker for yeast, and a polylinker.

Y-intercept: In a regression analysis, the value of y when x is zero.

Y-linked (holandric [“wholly male”]) trait: A trait due to a mutant gene carried on the Y chromosome but with no counterpart on the X.
