Triploid organisms have copies of each chromosome?
Triploid organisms have ___two___ Copies of each chromosome?
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.
What is meant by a triploid organism?
The diploid cell is one wherein each chromosome has its homologous counterpart for pairing during meiosis. Diploid cells are formed by gametic union and after completion of meiosis in a diploid cell haploid cells are formed. These haploid cells get converted into gametes to unite again to form the diploid cell.
In humans the shorter of the sex chromosomes?
In humans, the Y chromosome is noticeably shorter than the X chromosome.
Can you live with a y-chromosome and no x-chromosome?
No. The human X chromosome contains over 1000 genes, many of which are essential for life. The Y chromosome in comparison has only about 120 genes. A zygote with Y0 or YY (one or two Y chromosomes) would not be viable.
Triploid organisms have copies of each chromosome?
Triploid organisms have ___two___ Copies of each chromosome?
When cells contain three copies of a chromosome it is called?
Triploid.
Why do you think in humans there are no viable trisomies of chromosome 1?

If the chromosome no of a plant is 16 what would the chromosome no of the ploidy level of the microspore mother cell and the endosperm cells be?
Mmc's=16 as its diploidendosperm=48 as it is triploid 3n
What is meant by a triploid organism?

Diploid cells are formed by gametic union and after completion of meiosis in a diploid cell haploid cells are formed. These haploid cells get converted into gametes to unite again to form the diploid cell.
If a cell of a usually diploid species with 42 chromosome per cell is triploid this cell would be expected to have?
If a diploid number is 42, then the haploid number is 21. A triploid number would be 63. But why would you have the chromosomes from 3 parents combining?
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.
What are aoutosomes?
Any chromosome that is not a sex chromosome. humans have 44
In humans the shorter of the sex chromosomes?
In humans, the Y chromosome is noticeably shorter than the X chromosome.
In humans a male has?
one X chromosome and one Y chromosome
What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
Which sex chromosome determines if an offspring is male or female in humans?
In humans, which sex chromosome determines if an offspring is a male or female?
