The principal effects are development of small testicles and reduced fertility.
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
The male chromosome is officially known as the Y chromosome.
It has the same number of chromosomes as an adult, that is 23 pairs.
A person with an X and Y chromosome typically identifies as male. The presence of the Y chromosome determines male sex development, leading to the development of male characteristics during puberty.
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
Maleness is not a genotype but a combination of sex chromosomes. A normal human male has an X as well as a Y chromosome.
they have a extra chromosome, a normal male is XY, a male with klinefelters is XXY.
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
XY
A normal male has 46 chromosomes in total, with one X and one Y chromosome (XY) that determine male sex. The Y chromosome carries genes responsible for male characteristics, while the X chromosome carries various other genes essential for development and functioning of the body.
XY
A boy typically results from the combination of an X chromosome from the mother and a Y chromosome from the father, creating a male offspring with the genetic makeup XY. This combination determines the male sex in humans. The presence of the Y chromosome triggers the development of male characteristics during embryonic development.
A normal male will have one X and one Y chromosome.
The male chromosome is officially known as the Y chromosome.
A male individual is produced when a sperm carrying a Y chromosome fertilizes an egg carrying an X chromosome.
The genetic method involve the release of sterile male mosquitoes into the environmet. When the sterile male mosquito mates with a normal female mosquito, the latter does not lay any eggs. If enough sterile male mosquitoes are released into the environment, the mosquito population will eventually die out.
"Sterile" men have sperm with low motility rates (meaning there either isn't as many sperm as normal, or the sperm that is there is not as active as normal). This makes it much harder than normal for that male to fertilize an egg. How likely it is that he MIGHT still fertilize largely depends on what is causing the 'sterility'.
