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 else can I help you with?
In humans the genotype xx results in a?
It results in a female:) im pretty sure you go to primavera like me, biology is tough isn't it?
A karyotype of a human female shows that she has only one sex chromosome what is the genotype for her condition?
The genotype for this condition is Turner syndrome, which is characterized by a single X chromosome (usually denoted as 45,X). This results in a female individual with certain physical characteristics and potential health complications.
What are the sex chromosomes for a male and how do they determine biological sex?
The sex chromosomes for a male are XY. The presence of a Y chromosome determines male biological sex, while the absence of a Y chromosome results in female biological sex.
What fact expains why half of kids are boys and half are girls?
An ovum will have an X chromosome regardless, but a sperm has a 50% chance of having either an X or a Y chromosome, so there's a 50% chance a zygote will be XY (male) and 50% that it will be XX (female).
What chromosomes typically make up the sex chromosomes in a human male, and how do they determine the individual's biological sex?
The sex chromosomes in a human male typically consist of one X chromosome and one Y chromosome. The presence of a Y chromosome determines the individual's biological sex as male, while the absence of a Y chromosome results in a female biological sex.
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.
Explain how the sex chromosomes determine the sex of the offspring?
The sex chromosomes inherited from the parents determine the sex of the offspring. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of a Y chromosome results in the development of male characteristics, while the absence of a Y chromosome leads to the development of female characteristics.
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?
Which chromosome from the sperm is necessary to produce a female?
Y chromosome
What determines the gender of children?
the sperm cell that fertilizes ; y is a boy ; x is a girl
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 )
