How many of the 46 chromosomes are gametes?
Gametes are a specific class of cell, which contains chromosomes. Gametes are not a type of chromosome. Most cells in the human body are "diploid," which means they contain two copies of the 23 chromosomes, for a total of 46 chromosomes. Of those, two are sex chromosomes: classified as X or Y. Gametes, however, are reproductive cells: egg cells in the female, and sperm cells in the male. Gametes are "haploid," which means they only contain one copy of of the 23 chromosomes, and only one sex chromosome (an X in an egg cell, or an X or Y in a sperm cell).
Which cells have only 23 unpaired chromosomes?
The only place you would be able to find a cell with 23 chromosomes would be in the sex cells (sperm cells of egg cells). There are 46 chromosomes in the human body. This is because when a sperm cell fertilises the egg cell, both with 23 single chromosomes, they join to make 46.
Does each egg and sperm cell contain a full set of 46 chromosomes?
No, each egg and sperm cell contain half the number of chromosomes found in a normal body cell, which is 23. When an egg and a sperm cell combine during fertilization, they create a new cell with the full set of 46 chromosomes.
How many chromosomes does a fertilised egg have?
A fertilized egg, or zygote, typically has 46 chromosomes. This is a result of the coming together of the egg (23 chromosomes) from the mother and the sperm (23 chromosomes) from the father during fertilization.
The XX and XY chromosomes which are responsible for the inheritance of gender?
female eggs r all same having 22+x as genetic material..but male sperm is of 2 types 22+x &22+y...if 22+x crosses with egg,it result in44+xx which is a female...but if 22+y crosses with egg,it result in 44+xy i.e.male
Do egg cells contain either X or Y chromosomes?
The female egg caries two X's(XX) and the male caries XY
Can a females egg have a y chromosome?
No, men have an X and a Y, while women have two X's. {They don't usually, but... 'There is a whole lot more to maleness and femaleness than X or Y chromosomes. About 1 in 20,000 men has no Y chromosome, instead having 2 Xs. This means that in the United States there are about 7,500 men without a Y chromosome. The equivalent situation - females who have XY instead of XX chromosomes - can occur for a variety of reasons and overall is similar in frequency'.}
How do you tell if an egg will be a male or a female inside the womb?
an egg consists of x and Y chromosomes if an egg has 2 y cromosones it will be a boy but if an egg has 1 x and 1 Y cromosone it will be a girl.
What depends to born a male child in a human being?
The egg has two chromosomes and these are X and X where as a sperm has X and Y chromosomes, when an X form the egg and a Y from the sperm are put together you get a male.
How many male chromosome are found on an egg cell?
First off, the syntax of your question is off. Male chromosomes are XY and there are chromosomes INSIDE the egg. If the egg is not fertilized, there is only an X. If it is, it could add an X or a Y from the male, making it XX female or XY male.
How do you become a boy or girl?
Sex is determined by a pair of sex chromosomes. Males have XY chromosomes and females have XX chromosomes. In the fertilization stage where the sperm combines with the egg, the sex of the offspring depends on whether the sperm carries a X or Y chromosome. The ovum always carries a X chromosome because females only have X chromosomes. So, if the sperm carries the X chromosome, the offspring will have XX chromosome and becomes a girl. If it carries the Y, the baby becomes a boy. X (sperm) + X (egg) = XX (female) Y (sperm) + X (egg) = XY (male)

How many chromosomes in typical human sperm?
23 chromosomes (22 autosomes + Y chromososm or X chromosomes)
Which chromosomes is found only in the male?
Y Chromosome!
Is there an X or Y chromosome in an egg?
An egg will have the X chromosome and the sperm will have an X or Y chromosome.

What might happen if an egg cell received two X chromosomes during meiosis instead of one?
The offspring could have three X chromosomes or two X chromosomes and a Y chromosome.
