What else can I help you with?
Can an embryo develop with one x chromosome?
Yes, an embryo can develop with one X chromosome, rather than the XX or XY chromosome pair. An example of this is girls born with Turner's syndrome, who have only one X chromosome.
What chromosome tells us the sex of a human?
The X and Y sex chromosomes. If the embryo inherits an X and Y chromosome, it will be male. If the embryo inherits two X chromosomes, it will be female.
Why does mitosis occur in the whitefish embryo?
The reason why mitosis occurs in the whitefish embryo is because of the fact that it is made up of dividing cells. It is the best place to see mitosis due to rapid cell division caused by the growth of the fish embryo.
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
Why do you think in humans there are no viable trisomies of chromosome 1?
they are lethal and cause spontaneous abortion of the embryo early in development.
Can an embryo develop with one x chromosome?
Yes, an embryo can develop with one X chromosome, rather than the XX or XY chromosome pair. An example of this is girls born with Turner's syndrome, who have only one X chromosome.
An embryo is always stimulated to develop into a female because it?
An embryo is not always stimulated to develop into a female. The presence of the Y chromosome leads to the development of a male embryo through the expression of genes that promote male characteristics. In the absence of the Y chromosome, the default pathway is for the embryo to develop into a female.
What determines whether an embryo will become male or female?
The sex of an embryo is determined by the presence or absence of a Y chromosome. If the embryo has a Y chromosome, it will develop as male. If no Y chromosome is present, the embryo will develop as female.
What is y-chromosoze?
Y chromosome is the 2nd chromosome in a male homolouge it has the contribution in sex determination of the embryo.
What chromosome tells us the sex of a human?
The X and Y sex chromosomes. If the embryo inherits an X and Y chromosome, it will be male. If the embryo inherits two X chromosomes, it will be female.
What would happen to the chromosome number in the offspring if meiosis did not occur?
we will get a zygote with triploid chromosomal content,but this case is inviable so the embryo will die after a certain period.
How many chromosomes are in a mouse's gamete?
Gametes only have one set of each chromosome pair so that when two gametes come together, the chromosome number in the embryo is correct. There are 19 autosomes and one sex chromosome in the mouse gamete.
Why does mitosis occur in the whitefish embryo?
The reason why mitosis occurs in the whitefish embryo is because of the fact that it is made up of dividing cells. It is the best place to see mitosis due to rapid cell division caused by the growth of the fish embryo.
What chromosome number is diabetes type 2?
Chromosome number 20.
Is an embryo male or female?
In the early stages of development, an embryo's sex is not yet determined. The sex of the embryo is determined by the presence or absence of a Y chromosome from the father. Once the sex chromosomes are determined, the embryo will develop into a male or female.
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
How is the sex of an embryo determined?
The sex of an embryo is determined by the combination of sex chromosomes inherited from the mother and father. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of a Y chromosome triggers the development of male characteristics.
