How many homologous chromosomes in a haploid organism?
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
How many chromosomes in allium cepa?
Allium cepa, also known as onion, has a total of 16 chromosomes. These chromosomes exist as eight pairs, with each pair consisting of two homologous chromosomes.
How is the fidelity of meiosis is ensured?
Fidelity in meiosis is ensured through various mechanisms, such as the pairing of homologous chromosomes during prophase I, the crossover of genetic material between homologous chromosomes, and the alignment of chromosomes on the metaphase plate during metaphase I. Additionally, checkpoints exist to monitor the process and ensure accurate chromosome segregation during anaphase I and anaphase II.
Where do chromosomes exist?
Chromosomes exist within the nucleus of a cell. They are thread-like structures made up of DNA and proteins that carry genetic information in the form of genes. During cell division, chromosomes condense to become visible under a microscope.
Suppose that disjunction did not occur in one homologus pair of chromosomes during anaphase 1. How would this affect the chromosome number in the daughter cells?
the chromosome number would vary in daughter cells because disjunction involves the separation of the duplicated chromosomes. disjunction is the whole process occurring in anaphase, so it would be as if anaphase didn't exist. cells would go straight from duplicating chromosomes to splitting. chromosome numbers in daughter cells would therefore be uneven and random because of the cell just splitting in half and whatever chromosomes being in the daughter cell being there

If both homologous chromosomes of each pair exist in the same nucleus that nucleus is?
diploid
How would you know if 2 chromosomes were homologous pairs?
Homologous chromosomes are similar in size, shape, and genes. They are typically present in pairs, one inherited from each parent. To determine if two chromosomes are homologous pairs, genetic analysis, such as karyotyping or DNA sequencing, can be performed to compare their structure and content.
When do homologues pair?
A homologous pair is a pair of chromosomes that exist in diploid cells. One of the pair you inherit from your father, the other from your mother. A human has 22 pairs of homologous chromosomes (these do not include sex chromosomes). They are the same length and shape. They also share the same genes. The sequences of the genes may be different, which is what results in genetic variation, but the genes are the same.
How many chromosomes in allium cepa?
Allium cepa, also known as onion, has a total of 16 chromosomes. These chromosomes exist as eight pairs, with each pair consisting of two homologous chromosomes.
Describes an Organism that can exist a group of cells?

Do all livig things have chromosomes?
Yes all living things, (starting from a cell) have chromosomes. chromosomes are found in DNA and if cells didn't have DNA they wouldn't exist.
How many chromosomes are in cats diploid cell?
There are 38 chromosomes in a cat's diploid cell. Diploid cells always have an even number of chromosomes because they exist in pairs.
Where are alleles located?
Alleles are located on chromosomes, which are found in the nucleus of a cell. They can exist in pairs on homologous chromosomes, with one allele from each parent. Alleles are the different forms of a gene that can code for different traits or characteristics.
How many chromosomes are in body cells?
That depends completely upon the Species of the Body. The human body's Cells possess 46 individual chromosomes except that they are not actually individual because they actually exist in a paired configuration that yeilds 23 Chromosome Pairs.
