Mar 24, 2023 · Sex-linked or sex-linkage (related terms) qualities are characteristics that are present on either the sex-determining chromosome or the sex chromosomes. Understanding sex-linked traits is essential for grasping basic genetics. Genes situated on the X-chromosome are thus termed X-linked, and are transmitted by both males and females, while genes situated on the Y-chromosome are termed Y-linked, and are transmitted by males only. In humans, the X (female) chromosome carries many genes, whereas the Y (male) chromosome is deficient in genes. This is because sex determination in humans depends on the chromosomes that are obtained. Sex-linked character, observable feature of an organism controlled by genes on the sex chromosomes. This chromosome is gene-poor and a specific area called sex-determining region on Y is responsible for the initiation of the male sex determination.

In criss-cross inheritance, an X-linked recessive gene is transmitted from P1 male parent (father) to F2 male progeny (grandsons) through its F1 heterozygous females (daughters), which are called carriers) and different F1 and F2 results (ratios) in the reciprocal crosses. Oct 4, 2019 · Sex chromosomes are different from autosomal chromosomes in that the X chromosome is larger than the Y chromosome and, not surprisingly, the distinct sizes entail that each sex chromosome contains different genes (even though there are some genes that are coded in both X and Y chromosomes, but these are not considered sex linked genes). Sex linkage describes the sex-specific patterns of inheritance and expression when a gene is present on a sex chromosome (allosome) rather than a non-sex chromosome ().
