1. Y chromosome

   The Y chromosome is one of two sex chromosomes (allosomes) in therian mammals, including humans, and many other animals. The other is the X chromosome. Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers male development. The DNA in the human Y chromosome is composed of about 59 million base pairs, making it similar in size to chromosome 19. The Y chromosome is passed only from father to son. With a 30% difference between humans and chimpanzees, the Y chromosome is one of the fastest-evolving parts of the human genome. The human Y chromosome carries 693 genes, with 107 of these being protein-coding, but some genes are repeated and that makes the number of exclusive protein-coding genes just 42, the numbers are given for telomere-to-telomere CHM13. CCDS only classified 63 out of 107. All single-copy Y-linked genes are hemizygous (present on only one chromosome) except in cases of aneuploidy such as XYY syndrome or XXYY syndrome.

1. y chromosome

   The Y chromosome is one of the two sex chromosomes in mammals, including humans, and many other animals. It carries the genetic material that determines male sexual characteristics. In most species that use this system, including humans, individuals have two sex chromosomes, either two X chromosomes (making them female) or one X and one Y chromosome (making them male). The Y chromosome also contains genes that are critical for male fertility.

1. Y chromosome

   The Y chromosome is one of two sex-determining chromosomes in mammals, including humans. In mammals, the Y chromosome contains the gene SRY, which triggers testicle development if present. The human Y chromosome is composed of about 50 million base pairs. DNA in the Y chromosome is passed from father to son, and Y-DNA analysis may thus be used in genealogical research. With a 30% difference between humans and chimpanzees, the Y chromosome is one of the fastest evolving parts of the human genome.

1. Y Chromosome

   The male sex chromosome, being the differential sex chromosome carried by half the male gametes and none of the female gametes in humans and in some other male-heterogametic species in which the homologue of the X chromosome has been retained.

Examples of y chromosome in a Sentence

1. Arthur Georges:

   We used a bacterial artificial chromosome library to generate and verify sex specific sequence and probes that were important to determine the underlying sex of individuals, a BAC library is constructed by cutting up the dragon DNA, the whole genome, and inserting the fragments into bacterial colonies, one fragment per colony, so you can pull particular dragon sequence out at will.

2. Rod Mitchell:

   This study is particularly neat because it takes advantage of errors that are known to occur during culture of XY cells, which lead to loss of the Y chromosome and subsequent gain of a second X chromosome, resulting in XX cells that are capable of generating live offspring.

3. Sriram Sankararaman:

   You’re going along the genome and there is the X chromosome or there are genes expressed in testes. Basically, these parts of the genome have less Neanderthal or Denisovan.

4. Ron Estes:

   Having one more chromosome should never be validation for ending life, and the Protecting Individuals with Down Syndrome Act protects individuals with disabilities, this is common sense legislation that will save precious lives.

5. Sriram Sankararaman:

   We see a lot less compared to the rest of the genome, you’re going along the genome and there is the X chromosome or there are genes expressed in testes. Basically, these parts of the genome have less Neanderthal or Denisovan.
