Refers to a chromosome involved in defining the sex of an individual. Humans have two sex chromosomes and 44 autosomes. In females, both sex chromosomes are X chromosomes. Males have one X chromosome and one Y chromosome.
One of the chromosomes (X or Y) involved in sex determination. Normal human females have two X chromosomes in each cell, while normal males have one X and one Y.
In organisms with a chromosomal mechanism of sex determination, one of the chromosomes involved in sex determination.
The X and Y chromosomes are called sex chromosomes, because they contain the information which makes an individual male or female.
Sex chromosomes determine the sex of an individual. In humans, the two sex chromosomes happen to make up the last (23rd) pair of chromosomes. See Figure B-10.
One of two chromosomes in humans that defines sex. There are two sex chromosomes, the X and the Y chromosome. Males have one X and one Y chromosome, while females have two X chromosomes.
A chromosome that's either the X-chromosome (a pair confers femaleness in a normal diploid complement of chromosomes) or the Y-chromosome (just one confers maleness in a normal diploid complement of chromosomes); distinct from the non-sex chromosomes, or autosomes (which are numbered from 1 to 22); aneuploidies give rise to Turner syndrome, Klinefelter syndrome, triple-X syndrome, extra-Y-chromosome syndrome) etc; examined in a karyotype.
(genetics) a chromosome that determines the sex of an individual; "mammals normally have two sex chromosomes"
Refers to the two chromosomes (X and Y) that determine the sex of an individual.
the chromosome s whose gene s confer the sex of the organism. In humans, it is the X chromosome and Y chromosome. Normally, men have an X and Y chromosome while women have two X chromosomes.
One or the two chromosomes that specify an organism's genetic sex. Human property two kinds or sex chromosomes, one called X and the other y.
The 23rd pair of chromosomes in humans are the sex chromosomes. Females have two X chromosomes and males have an X and a Y chromosome.
One of the two chromosomes that specify an individual's sex. Humans have two sex chromosomes (X and Y). Females have two X chromosomes and males have one X chromosome and one Y.
The X- or Y-chromosome. Normally males have one X and one Y and females have two Xs.
These chromosomes determine male or female sex and come in two forms, X and Y. Normal females have two X chromosomes, males an X and a Y.
The X and Y chromosomes which are responsible for sexual development. In humans, females have two X chromosomes while males have an X and a Y. Genes on the Y chromosome are responsible for male sexual development.
The 23rd pair in a karyotype; females have two X chromosomes, males have an X and a Y chromosome.
the X or Y chromosome, which determines sex. Females have two X chromosomes in each cell, and males have an X and a Y.
A chromosome involved in sex determination; in humans, the X and Y chromosomes.
heteromorphic chromosomes whose distribution in a zygote determines the sex of the organism
an X or Y chromosome; the Xx pair determines female and the XY pair determines male
a chromosome (X or Y) that determines the sex of an individual. Females have two X chromosome and males have an X and Y.
The X or Y chromosome in human beings that determines the sex of an individual. Females have two X chromosomes in diploid cells; males have an X and a Y chromosome. The sex chromosomes comprise the 23rd chromosome pair in a karyotype.
A sex chromosome is one of the two chromosomes that specify an organism's genetic sex. Humans have two kinds of sex chromosomes, one called X and the other Y. Normal females possess two X-chromosomes and normal males one X and one Y. [ Talking Glossary
A chromosome whose presence or absence is correlated with the sex of the bearer; a chromosome that plays a role in sex determination.
