Explain why a diploid nucleus has homologous chromosomes but a haploid nucleus does not?
A 2n nucleus has a complete set of chromosomes. One set fro the mother and one set from the father equals two sets. A 2n nucleus has homologous chromosomes because it has one paternal homolog and one maternal homolog from the parents. So, an (n) nucleus has half the number of chromosomes and does not have any homologous chromosomes because its 2n nucleus has gone through a reductive division and now only has one set of chromosomes.

What is the difference between a haploid cell and the diploid cell?
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
What is the difference between a diploid cell and a haploid cell?
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
Are homologous chromosomes present in diploid or haploid cells?
Homologous chromosomes are present in diploid cells, which contain two sets of chromosomes (one inherited from each parent). In contrast, haploid cells contain only one set of chromosomes.
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.
What is the difference between a haploid cell and diploid cell?
A haploid cell contains a single set of chromosomes (half the normal number), typically found in gametes (sperm and egg cells). In contrast, a diploid cell contains two complete sets of chromosomes, one from each parent, and is found in most somatic cells of the body.
What cell has homologous chromosomes?
A diploid cell has homologous chromosomes. Diploid cells contain two sets of chromosomes, with one set inherited from each parent. The homologous chromosomes have similar genes in the same order, but may have different versions of those genes.
How does the number of chromosomes in a diploid compare to the number of chromosomes in a haploid?
The diploid number is "2n" and the haploid number is "n". Humans have 46 chromosomes, which are equal to the diploid number. half of these chromosomes are the haploid number, which is = 23.
When Homologous chromosome pairs?
What term could be defined as "Pictoral representations of the homologous pairs of chromosomes
When gametes combine to form a zygote the chromosomes number of the zygote is now referred to as?
diploid is what the total number of chromosomes in an organism is
Do you agree or disagree that homologous chromosomes are found in gametes. explain?
Have to say Nay. Two chromosomes are 'homologous' , to my understanding, only if each is IDENTICAL with the other - this means a pair. Gametes are haploid, meaning that only one copy of each (normally diploid or paired) chromosome (s) is (are) present.
When a cell contains only one chromosome of each homologous pair the cell is?
ploidy is the classification based on the number of homologous chromosomes present. if there is only one pair of homologous chromosomes then the nucleus is said to be haploid if there are two pairs then it is known as diploid if three it is triploid if many it is noted as polyploidy --------------------------- an oocyte or a spermatocyte are haploid cells in a species that normally have diploid cells.
Is 2n haploid or diploid?
2n is diploid, as it represents the full set of chromosomes in an organism where n represents the haploid number of chromosomes.
