XY sex-determination system

gonadal intersex occurs when the person has both: ovarian and testicular tissue. The person may have XX chromosomes, XY chromosomes, or mix of both. The external genitals may appear as male, female or be ambiguous. The underlying cause is unknown, but some studies link it to common agricultural pesticides exposure. 4. Complex or undetermined intersex disorders of sexual development, where multiple chromosome configurations such as 45 XO, 47 XXY, 47 XXX disrupt proper sex development. In this case, there is no discrepancy between internal and external genitalia, but there are issues with sex hormone levels, overall sexual development, and altered numbers of sex chromosomes. The symptoms associated vary due to the underlying cause, and may include: an enlarged clitoris, micropenis, ambiguous genitalia at birth, partial labial fusion, hypospadias, electrolyte abnormalities, delayed/absent puberty, undescended testes, labial or inguinal masses, and unexpected changes at puberty. Tests used to obtain proper diagnosis are: chromosome analysis, hormone stimulation tests, electrolyte tests, molecular testing, endoscopic exam, ultrasound, and…

SIMULATION CROSS BETWEEN A HETEROZYGOUS FEMALE AND A HEMOPHILIA MALE BACKGROUND INFORMATION The survival of the human species throughout the last millions of years has been solely based on the randomized process of genetic inheritance from one generation to the next generation. Instead of duplicating their genetic information and create identical offspring, humans produce sex cells, through the process of meiosis, that carry only half of the genetic information, and fertilize them in order to…

Oppression have been international issues for generations, from the Civil War in the 19th century to the Holocaust in the 1940s, and the comments of Donald Trump in 2016. All of these issues affect each of us differently, but we can all agree that there is still much progress to be made in ensuring that every human being is treated equally. However, we cannot truly understand why an individual feels the way they do about any of these issues until we know the background and history behind those…

gender from the obvious facial features. The biological gender is born with each other, it would not change because of the different race, country and culture. We called Sex. Sex determine people from their biological structure and anatomy structure. Biological structure is the difference of chromosome, and anatomy structure is the difference of organ. The sexual difference cannot change. On biological side we called Sex, on…

Sexual differentiation in monomorphic avian species Madeleine Evans ID: 213023921, Deakin University Waurn Ponds, Course S323 Biomedical Science, Subject SLE254 Genetic Introduction Sexual differentiation is one of the first biological processes to occur during the development of a foetus. There are a variety of methods for sex determination amongst vertebrates including analysis of primary and secondary differentiations. Primary differentiation refers to the presence of gonads, while secondary…

nurture on an individual’s sex and gender. It can be argued that ‘biology is fate’ in regards to this but there are, however, many other influencing factors that can shape and dilute this ‘fate.’ Social norms, upbringing and the culture one lives in can heavily impact how and with who one identifies themselves. Sex and gender are subjective matters that cannot be generalized as a common ‘fate,’ but rather depend entirely on each individual’s experience. Sexuality is defined as the biological…
