Is a karyotype an organized display of an organism's chromosomes?
Yes, a karyotype is a display of an organism's chromosomes (generally in homologous pairs from largest to smallest).
What happens when chromosomes line up?
When chromosomes line up this is generally part of mitosis or meiosis... the process of replicating or splitting and becoming gametes (sex cells).
What is X chromosome?
The x chromosome is one of the sex chromosomes, the other being the y chromosome. In mammals there are two of the sex chromosomes in each organism. Females generally contain two x chromosomes, and males contain one x chromosome and one y chromosome.
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
What is generally accepted as the origin of living organisms?
Prebiotic chemical evolution gave rise to progressively more complex molecules and eventually to living organisms
How organisms in the domain eukarya from those in the domain archaea?
Organisms in the domain Eukarya have membrane-bound organelles, a nucleus, and multiple linear chromosomes, while organisms in the domain Archaea lack membrane-bound organelles, have a single circular chromosome, and their cell walls are chemically different. Eukaryotes generally have more complex cellular structures and processes than archaea.
Is a karyotype an organized display of an organism's chromosomes?
Yes, a karyotype is a display of an organism's chromosomes (generally in homologous pairs from largest to smallest).
After fertilization how is the cell similar to and diffferent from the original cell?
Do you mean the similarities and differences between the new set of chromosomes and the parents' chromosomes? Or do you mean to ask about the comparison of the egg before/after fertilization?Only egg cells are fertilized.After fertilization, the egg should contain a complete set of chromosomes for the specific animal.If you meant the difference between the new set of chromosomes and the parents' individual chromosomes, the new set will generally contain the dominant genes of each gene type, and a few (generally minor) mutations. These mutations are what keep the organisms from slowly running out of non-relatives to breed with, in which case they would have had some severe genetic problems, as they would be amplified (which is the major problem of in-breeding).
The phase where the independent chromosomes move to the poles?
well, "independent chromosomes" would be more like Anaphase I from meiosis; otherwise, it would be generally Anaphase. (it is not chromosomes but chromatids though, in mitotic anaphase.)
Traits are determined by pairs of genes called?
The two chromosomes (two "X" shapes) that are in a pair are generally called "homologous chromosomes". A pair of "chromatids" make up the two arms of a single chromosome.
Are rain forests generally dense with living organisms?
no
What happens when chromosomes line up?
When chromosomes line up this is generally part of mitosis or meiosis... the process of replicating or splitting and becoming gametes (sex cells).
What is the appearance and number of chromosomes in the cell of a nucleus?
This differs depending on the animal you are talking about. Humans generally have 46 chromosomes. Dolphins have 44. Dogs have 78. A Chimpanzee has 48.
Are humans typical organisms?
Humans are generally not considered typical organisms. In fact, humans are often considered unique organisms simply due to their complexity.
Does an animal have more chromosomes than a plant?
possibly, different animals have different chromosome numbers, as do plants... so the chances are that yes there will be some plants that have the same amount of chromosomes as certain animals have... but they could never combine or cross with each other
Generally are single-celled organisms prokaryote or eukaryote?
Prokaryotes
Where in the cell is chromomsoes located?
The chromosomes, in their chromatin form generally, are located in the organelle called the nucleus.
