Source sentences:
text: In mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development as a male.
text: The Y chromosome is small, carries few genes, and has abundant repetitive sequence, while the X chromosome is more autosome-like in form and content.
text: Male chromosome or Y chromosome contains many genes determining various characteristics.
text: The Y chromosomes contain only a few genes, while X chromosome has more than 300 genes.
text: The early “proto-Y” chromosome was originally the same size as the X chromosome and contained all the same genes.
text: In mammals, the Y chromosome contains the gene SRY, which triggers male development.
text: The presence or absence of the Y chromosome is critical because it contains the genes necessary to override the biological default - female development - and cause the development of the male reproductive system.
text: Females carry only the X chromosome, while males carry both X and Y. The X and Y chromosomes carry different genes, and the Y chromosome contains the genes that code for male attributes.
text: These conditions, each of which occurs in about 1 in 1,000 live births, are clinically mild, perhaps reflecting the fact that the Y chromosome carries relatively few genes, and, although the X chromosome is gene-rich, most of these genes become transcriptionally silent in all but one X chromosome in each somatic cell (i.e., all cells except eggs and sperm) via a process called X inactivation.
text: Many generations ago the Y chromosome was large, and contained as many genes as the X chromosome.
text: The number of genes carried by autosomes varies from 200 to 2000, but in case of sex chromosomes, the Y chromosomes contain only a few genes, while X chromosome has more than 300 genes.
text: The early “proto-Y” chromosome was originally the same size as the X chromosome and contained all the same genes.
