Summary of Inheritance Sex Linked Traits Meiosis Related to Genetics Objective The objective of this study is to summarize inheritance sex linked traits meiosis related to genetics. Introduction Meiosis is reported to produce "four genetically varied gametes (eggs or sperm cells) out of a diploid cell.". Sex-Linked Traits Through Meiosis and How It Relates to Genetics. learn general concepts that are associated with genetics and to create a better understanding of inheritance and its’ relationship to genetic diseases. According to standards set by the Next Generation Science Standards which are endorsed by the National Science Teachers.

Sex-linked traits are associated with genes found on sex chromosomes (X and Y). As the female X-chromosome is larger, X-linked traits are more common than Y-linked traits. An example of a sex-linked trait is red-green colorblindness, which is carried on the X-chromosome. Meiosis is a type of cell division where the daughter cells to be formed is not similar to their mother cell in terms of genetic contents. Generally, this type of cell division happens to sex.

Simple organisms pass on genes by duplicating their genetic information and then splitting to form an identical organism. More complex organisms, including humans, produce specialised sex cells (gametes) that carry half of the genetic information, then combine these to form new organisms. The process that produces gametes is called meiosis. The inheritance of a trait (phenotype) that is determined by a gene located on one of the sex chromosomes is called sex linked inheritance. The expectations of sex-linked inheritance in any species depend on how the chromosomes determine sex. For example, in humans, males are heterogametic. It has one X chromosome and one Y chromosome.

Feb 07, · One allele for a trait is inherited from each parent. Like traits that originate from genes on autosomes (non-sex chromosomes), sex-linked traits are passed from parents to offspring through sexual reproduction. During meiosis the male XY sex-chromosome pair separates and passes on an X or a Y to separate gametes; the result is that one-half of the gametes (sperm) that are formed contains the X chromosome and the other half contains the Y chromosome.
