you need one chromosome from one parent and one from the other parent. These homologous pairs each have the same genes but different alleles. For instance, one may code for black hair while the other codes for brown hair. You need both to be present in order to have both the parents traits.

Is homologous chromosomes only present in cells that undergo meiosis?
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
What is the Disjunction of homologous chromosomes to the opposite poles?
During anaphase, the centrosomes (which have moved to opposite poles of the cell) release microtubules from their centrioles which then pull the chromosomes towards them, the double stranded chromosomes then split at the centromere and thus each pole of the chromosome has a copy of every chromosome. I assume you're talking about meiotic division though and in this case the spindle fibres/ microtubules dont split the chromosomes in half, rather, the chromosomes line up in homologous pairs (instead of in single file) and the spindle fibres pull one of the entire homologous double stranded chromosomes to its designated pole.
How many chromosomes are in each corn gamete?
some people dont know how many chromosomes are in corn plants. corn plants have 20 chromosomes humans have 46 and fruit flies have 4 pairs double the four pairs and then ur fruit flie has the total of 8 chromosomes
How many chromosomes does a bat in a haploid cells?
Y dont we know how many chromosomes does a bat have?we should know this for my class i mean come on 4realz u are not helping find this answerCola33: A bat has 8 choromosomes, which means that she/he has 4 pairs of chromosomes, I'm pretty sure.Y dont we know how many chromosomes does a bat have?we should know this for my class i mean come on 4realz u are not helping find this answerCola33: A bat has 8 choromosomes, which means that she/he has 4 pairs of chromosomes, I'm pretty sure.
When do the homologous chromosomes form tetrads?
Bivalents or Tetrad of homologous chromosomes consisting of four synapsed chromatids that become visible during the Pachytene stage of meiotic prophase or A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatids.

How many homologous chromosomes interact with each other or dont during mitosis and meiosis?
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.

Do homologous chromosomes always have identical alleles?
no they don't necessarily have to have the same alleles but they have the same genes. Homozygous chromosomes would have the same allele for a particular gene and heterozygous chromosomes would have different alleles for a particular gene.
How many cells do rabbits have?
There are 22 different chromosome pairs existing in each cell of the rabbit except the sex cells and red blood cells. Each chromosome pair controls different functions.
What does disjunction mean?
inclusive : pvq : one or both have to be true exclusive : pV ( with a line under it but i dont know how to do that on my aptop) q :ony one coud be true

How do the chromosomes divide between the new cells?
i dont know.. Ask someone who knows!
What happens during metaphase in the cell division?
Metaphase is the phase of cell division where chromosomes line up on the equator of the cell just prior to splitting to the poles at anaphase. During mitosis identical chromosomes pair up on the equator, wheras during meiosis the homologous pairs line up together during meiosis 1 and then homologous chromatids line up together in meiosis 2.
Which nucleotides pair together?
Pyrimidines in DNA is about equal to the percentage of purines. This is established by Chargoff's rule and is confirmed by the fact that base pairing of anything but a pyrimidine with a purine would be too wide or too narrow to fit within the backbones of a DNA strand
