What else can I help you with?
Do an egg only have y chromosomes?
No, eggs typically contain one X chromosome. Female reproductive cells (eggs) carry one X chromosome, while male reproductive cells (sperm) can contribute either an X or a Y chromosome. Thus, it is the combination of genetic material from the egg and sperm that determines the genetic sex of offspring.
What alleles do females carry but not males?
Females carry two copies of the X chromosome, while males carry one X and one Y chromosome. This means that females can have two different alleles for genes located on the X chromosome, while males can only have one allele for those genes.
What is the chance that a human zygote will receive one X and one Y sex chromosome during fertilization 100 percent 25 percent 75 percent 50 percent?
The chance that a human zygote will receive one X and one Y sex chromosome during fertilization is 50 percent. This is because an individual inherits one sex chromosome from each parent, with the father contributing either an X or a Y chromosome, and the mother contributing an X chromosome.
Which sex chromosome do sperm cells carry?
Sperm cells are of two types. One type carries a Y chromosome, while the other type carries an X chromosome. This is the reason why the Spermatid is the 'deciding factor' in whether a baby will be male or female. The Ovum always carries an X chromosome.
Who carries both X and Y chromosomes?
Individuals with Klinefelter syndrome have an extra X chromosome (XXY), resulting in the presence of both X and Y chromosomes. This genetic condition can lead to a variety of symptoms, such as reduced fertility and developmental delays.
What is the probablilty that a human sperm cell will carry an X chromosome?
The male gamete is comprised, on average, of 50% of the X chromosome and 50% of the Y chromosome.
Do an egg only have y chromosomes?
No, eggs typically contain one X chromosome. Female reproductive cells (eggs) carry one X chromosome, while male reproductive cells (sperm) can contribute either an X or a Y chromosome. Thus, it is the combination of genetic material from the egg and sperm that determines the genetic sex of offspring.
what cell contain only one sex chromosome?
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
If a female of this species has one chromosome 12 with a blue gene and another chromosome 12 with an orange gene she will produce egg types?
If a female of this species has one chromosome 12 with a blue gene and another with an orange gene, she will produce two types of eggs. Half of her eggs will carry the blue gene, while the other half will carry the orange gene. This genetic variation can lead to offspring with either blue or orange traits, depending on the combination of genes inherited from both parents.
What alleles do females carry but not males?
Females carry two copies of the X chromosome, while males carry one X and one Y chromosome. This means that females can have two different alleles for genes located on the X chromosome, while males can only have one allele for those genes.
What sex chromosome does a human egg cell contain?
The sex chromosome typically carried by an ovum is X-chromosome. The sperm may carry either x or y sex chromosome.
Do men carry only XX chromosomes?
Men typically have one X chromosome and one Y chromosome. Women typically have two X chromosomes. So-called XX males have two X chromosomes; thus they are genetically female but otherwise appear to be male.
What cell contains only one sex cell?
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
Will the eggs of a down syndrome women have extra chromosomes?
yes they will have one more chromosome
What chromosome do women carry?
All organisms carry a set number of pairs of chromosomes, in humans it is 23 pairs. Of these chromosomes one pair controls the sex of the human. The sex chromosomes are called the X and Y chromosome. Females have XX pairing and Males XY.
Why do fraternal twins don't have to be of the same sex?
Unlike identical twins, fraternal twins come from two separate eggs each getting fertilized by a separate sperm. Now these sperms can both carry an X chromosome or a Y chromosome giving rise to fraternal twins of the same gender. But at times one could carry the X chromosome and the other could carry the Y chromosome resulting in twins of opposite gender.
Why do all the daughters in generation 2 carry the colorblind gene?
In genetics, if a colorblind gene is located on the X chromosome, all daughters in generation 2 would inherit this gene from their father, who carries the colorblind trait. Since daughters receive one X chromosome from each parent, they will inherit their father's X chromosome carrying the colorblind gene, while receiving a second X chromosome from their mother. This results in all daughters being carriers of the colorblind gene. If the mother is not a carrier, the daughters will not express colorblindness but will carry the gene.
