  2. Y chromosome - Wikipedia

    en.wikipedia.org/wiki/Y_chromosome

    The human Y chromosome is composed of about 62 million base pairs of DNA, making it similar in size to chromosome 19 and represents almost 2% of the total DNA in a male cell. [54] [55] The human Y chromosome carries 693 genes, 107 of which are protein-coding. [56]

    en.wikipedia.org/wiki/Human_genome

    In 2021, scientists reported sequencing a complete, female genome (i.e., without the Y chromosome). [4] [3] The human Y chromosome, consisting of 62,460,029 base pairs from a different cell line and found in all males, was sequenced completely in January 2022. [5] The current version of the standard reference genome is called GRCh38.p14 (July ...

  4. Zygosity - Wikipedia

    en.wikipedia.org/wiki/Zygosity

    A diploid organism is heterozygous at a gene locus when its cells contain two different alleles (one wild-type allele and one mutant allele) of a gene. [3] The cell or organism is called a heterozygote specifically for the allele in question, and therefore, heterozygosity refers to a specific genotype. Heterozygous genotypes are represented by ...

    en.wikipedia.org/wiki/XY_sex-determination_system

    All animals have a set of DNA coding for genes present on chromosomes. In humans, most mammals, and some other species, two of the chromosomes, called the X chromosome and Y chromosome, code for sex. In these species, one or more genes are present on their Y chromosome that determine maleness.

    Since 2010, scientists have known that the Y chromosome is rapidly evolving in humans, but a new study shows that the same can be said across all Great Apes—the closest relatives to humans.

    While all human chromosomes contain repeats, more than 30 million letters of the Y chromosome — out of 62.5 million — are repetitive sequences, sometimes called satellite DNA or junk DNA.
