In Drosophila, the presence or absence of the Y chromosome does not affect the sex of the organism, but in the human Y chromosome determines the sex of the male. NOTE: This is why the XXY condition causes females in flies, but in humans the same condition causes Klinefelter syndrome in males.

What happens if XXY?

Children with XXY syndrome may need academic, social, and emotional support. Teens may enter puberty at normal times, but then decreased facial and body hair, decreased muscle development, smaller testicles, and swollen breasts (gynecomastia). Depression and anxiety can occur in this age group.

Does XXY karyotype produce males in Drosophila?

Sex determination in Drosophila

The balance between the female determinants encoded on the X chromosome and the male determinants encoded on the autosomes determines which sex-specific transcriptional pattern will be initiated.Therefore, XX, XXY and XXYY flies are femalewhile XY and XO flies were males.

What is the XXY genotype?

Klinefelter syndrome (sometimes called Klinefelter’s, KS, or XXY) is where boys and men are born with an extra X chromosome. Chromosomes are packages of genes found in every cell in the body. There are two types of chromosomes, called sex chromosomes, that determine the genetic sex of a baby.

How would XXY exceptions be affected?

Klinefelter syndrome (KS), also known as 47, XXY, is a syndrome Males have an extra copy of the X chromosome. The main features are infertility and small, poorly functioning testes. Often, symptoms are subtle and subjects are unaware that they are being affected.

In Drosophila, his XXY status results in feminization, but also in humans

Can XXY have children?

It is possible for an XXY male to conceive a female naturally. Although sperm are present in more than 50% of KS3 men, low sperm production can make conception very difficult.

We found that Klinefelter syndrome was associated with a significantly increased risk of death by 40% (hazard ratio, 1.40; 95% confidence interval, 1.13-1.74), corresponding to a significant reduction in Median survival was 2.1 years.

Are XXY males infertile?

95% to 99% of XXY males are infertile Because they don’t produce enough sperm to fertilize an egg naturally. However, sperm are present in more than 50% of men with KS.

What gender is the XXY chromosome?

A person’s biological sex is determined by sex chromosomes: female Have two X chromosomes, or XX; most men have one X chromosome and one Y chromosome, or XY. Men with XXY syndrome are born with cells with an extra X chromosome, or XXY.

What are examples of male heterosexual gametes?

Male heterosexuality includes Human males with XY sex chromosomes and males of certain insects with XO sex chromosomes. Female heterogamy includes females of certain birds, fish and insects. Platypus males are heterogametes, while females are homogametes. In Drosophila, males are heterogametes.

Who is responsible for the boy or the girl?

man decides The sex of a baby is determined by whether their sperm carries an X or Y chromosome. The X chromosome combines with the mother’s X chromosome to create a baby girl (XX), and the Y chromosome combines with the mother’s X chromosome to create a boy (XY).

What is the difference between XXY and XYY?

Can you have an XXY chromosome?

Klinefelter syndrome is a genetic disorder in which a boy is born with an extra X chromosome. Unlike the typical XY chromosomes in men, they have XXY, so this condition is sometimes called XXY syndrome.

Can a man with Klinefelter syndrome have children naturally?

But problems with their testicles prevent them from making enough normal sperm for the father and child.Most men with this disorder are infertile and cannot have children the usual way. Options for becoming a biological parent are limited, but fertility researchers are working on new treatments.

Who is most likely to have Klinefelter syndrome?

When is the result of Klinefelter Syndrome a boy was born At least 1 extra X chromosome. This is written as XXY. Klinefelter syndrome occurs in about 1 in 500 to 1,000 baby boys. Women who become pregnant after age 35 are slightly more likely to have a boy with the syndrome than younger women.

How does Klinefelter syndrome affect a person’s life?

Are Drosophila Male Heteroligands?

In insects, Lepidoptera (butterflies and moths) have heterogamous females, but in Drosophila, male is heterosexual… For example, most male D. melanogaster lineages are blind and lack recombination on all chromosomes, although females show recombination.

Are males in grasshoppers heterogametic?

Consider a male grasshopper heterogamy Because they produce two different types of sperm cells: with or without the X chromosome. However, female grasshoppers are XX and carry two X chromosomes. They are considered homogametes because all of their egg cells contain an X chromosome.
