How the 2 sex chromosomes compare to each other in female fruit flies?
There is a 50% chance of having a male or a female each time sex chromosomes and inherited. the 'X' chromosome is received from the mother. The 'Y' chromosome is received from the father.
When is the baby sex determined?
It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.
Explaine the sex of an infant is genetically determined at conception.?
Male sex is tied directly to the Y sex chromosome. The Y chromosome codes for the proteins and enzymes that cause the changes that makes one phenotypically male. Any fetus without a Y chromosome will be genotypically and phenotypically female, only by lack of those proteins and enzymes mentioned before. Given that one sex chromosome comes from the ovum and one comes from the sperm, which fuse at conception, the genotypic and phenotypic sex of the fetus is determined at the time of conceptual fusion of the spermatozoa and ovum.
How can you tell if a genetic disorder in a pedigree chart is sex linked?
In humans (and other animals with the XX/XY sex chromosome configuration) a sex linked trait will show up in sons 50% of the time and 0% of the time in daughters of a female carrier.The only way that a female can have the necessary phenotype/genotype to display the trait is for thefather to be affected and the mother to be a carrier or affected herself.
Why is hemophilia considered to be a sex-linked trait-?
It is carried on the X chromosome.
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.
How the 2 sex chromosomes compare to each other in female fruit flies?
There is a 50% chance of having a male or a female each time sex chromosomes and inherited. the 'X' chromosome is received from the mother. The 'Y' chromosome is received from the father.
How much charge flowed through the switch when it was closed?
The amount of charge that flowed through the switch when it was closed depends on the current passing through it and the time it was closed for.
What are sex chromosomes in a human male?
We call these sex chromosomes. Whether you are a male or female depends on the presence or absence of certain chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. If you have two XX, you will show female characteristics and If you have XY you will show male characteristics.
Why is the ratio of male to female births roughly 50-50?
Human females have two X chromosomes (XX), while males have an X chromosome and a Y chromosome (XY). During meiosis, these chromosomes segregate into separate gametes. All female ova carry a single X chromosome, while in males, half the sperm carry an X chromosome and half carry a Y chromosome. When these fuse together during fertilization, 50% of the time a sperm with an X will fuse with an ovum carrying an X, to generate an XX individual (female). The other 50% of the time, a sperm with a Y fuses with an ovum carrying an X to generate an XY individual (male). Hence, the 50-50 ratio of males to females is a direct result of half of male sperm carrying an X chromosome and half carrying a Y chromosome.
When is the baby sex determined?
It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.
Which equation connects charge current and time?
Current = charge / time
How long will 185 C of electric charge take to pass through the motor with a current of 350 mA?
To calculate the time it takes for the charge to pass through the motor, you can use the formula Time = Charge / Current. Plugging in the values, Time = 185 C / 0.35 A = 528 seconds. So, it will take 528 seconds for 185 C of electric charge to pass through the motor with a current of 350 mA.
Is that possiblity of changing gender after 23 weeks of preganncy?
Gender is determined at the time of conception. The fertilizing sperm carries either an X (female) or Y (male) chromosome. There is no gender-switching.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
what is the charge of X in XC2H3O2?
If you know the electric current, the flow of electric charge through an object, traveling through a circuit and how long the current is applied, you can calculate electrical charge using the equation for current Q = It in which Q is the total charge measured in coulombs, I is current in amps, and t is time that the ..
How do you calculate electric currents?
Electric current (in amperes) is calculated by dividing the electrical charge (in coulombs) by the time taken (in seconds) for the charge to pass through a given point in a circuit. The formula is I = Q / t, where I is the current, Q is the charge, and t is the time.
