Explain how the type of chromosome results in some children being male and others being female?

A child's gender is dependent on which chromosome (X or Y) is received from the father. The mother has the chromosomes XX and the father has XY. Each parent randomly gives the child one of their respective chromosomes (through meiosis). The mother gives one of her two X chromosomes and the father gives either the X or the Y. If the father gives a copy of his X chromosome, the baby is a girl. If the father gives his Y chromosome, the baby is a boy.

What does a Barr body in a mammalian female cell represents?
x chromosome... since female body has single type of chromosome, X chromosome
A human female inherits?
two copies of every gene located on the X chromosome.
Is blonde hair recessive or dominant?
Recessive gene of X chromosome. more common in men as they have only one x chromosome but in female there are 2 X chromosome. If one of X chromosome in female has this recessive gene, they become a carrier. If both the X chromosome in female has this gene, they show baldness
Finding an occasional vermillion-eyed female can be explained by the occurrence of an extra chromosome from the for the trait?
Finding an occasional vermillion-eyed female can be explained by the occurrence of an extra chromosome from the "female" for the trait.
What are the correct designation of the paired sex chromosomes?
the male chromosome is XY the female chromosome is XX
What TYPE of a sperm must fertilize an egg to result a female child?
X Chromosome results in a female Y Chromosome results in a male All sperm are either going to be an X or Y chromosome All eggs are X chromosome only
Turner's syndrome always results in female offsprings why?
Because people who have Turner syndrome have one X chromosome instead of the two other females have. As they do not have a Y chromosome, they are female.
What is the chance an X chromosome is inherited from a mother?
A female has the sex chromosomes XX. Therefore they will always pass an X chromosome on to their children.
Are children born male or female or is it decided at a later time as suggested by the gender schema?
It is actually decided at a earlier time, at conception. It depends on the chromosome in the sperm. If the sperm contains a X chromosome it will be female(all eggs contain an X chromosome) and if it contains a Y chromosome it will be male.
Which pair of chromosomes produces a male off-springs?
It depends which species you are. There is the XY system (which mammals use) where it is the presence of the Y chromosome that induces male development. The Y chromosome contains genes like Sry that initiate the male developmental program. Male mammals have an X and a Y chromosome, female mammals have two X chromosomes. However, for other species, like birds, use the so-called ZW sex chromosome system where it is actually the absence of the W chromosome that permits male development - male birds have two Z chromosomes and female birds have a W and a Z chromosome. And then there's the X0 system, which many insects use, where two copies of an X chromosome results in a female but a single copy of an X chromosome results in a male.
In human which sex chromosome determines if an offspring is a male or female?
In humans, which sex chromosome determines if an offspring is a male or female?
What does a Barr body in a mammalian female cell represents?
x chromosome... since female body has single type of chromosome, X chromosome
Which chromosome from the sperm is necessary to produce a female?
Y chromosome
What are the x and y chromazones?
The Y chromosome is the male sex chromosome, but males also carry a X chromosome from their mother. XY. The female sex chromosome is the Y chromosome; YY is female. ( generally, as sex chromosome number in both sexes can vary )
What determines the gender of children?
the sperm cell that fertilizes ; y is a boy ; x is a girl
What kind of chromosome do females transmit of offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
Is an x chromosome and chromosome the same thing?
An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
