How does the order of genes in one member of a chromosome pair compare to the order of genes on the other chrososme?
Most homologous pairs look alike. They carry genes for the same characteristics and line up on the chromosome in the same order!
What is the place on a chromosome that gives information for a protein?
The place on a chromosome that provides information for a protein is called a gene. Genes are segments of DNA that encode the instructions for synthesizing proteins, which perform various functions within the cell. Each gene consists of a specific sequence of nucleotides that determines the amino acid sequence of the protein it codes for. The expression of genes is regulated and can be influenced by various factors, leading to diverse protein functions in an organism.
What results if a fragment of a chromosome breaks off and then reattaches to the original chromosome at the same place but in the reverse direction?
This is a type of chromosomal rearrangement called an inversion. Inversions do not typically result in the loss or gain of genetic material, but can affect gene expression by disrupting the normal order and orientation of genes. Inversions can be inherited or arise spontaneously during cell division.
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
What joins chromosomes arms together and is the place where spindle fibers attach to each chromosome?
The structure that joins chromosome arms together is called the centromere. The centromere is essential for proper chromosome segregation during cell division and is the point where spindle fibers attach to the chromosome to facilitate this process.
How is a linkage map related to cross overs that take place during meiosis?
The more space there is between two genes on the same chromosome, the more likely it is that crossing over will take place between those two genes. Thus, by studying lots of examples of meiosis with crossing over, it is possible to make a map of the chromosome, with the genes (and the relative distances between them) laid out along it.

Do the continental plates remain in one place?
No, both the continental and oceanic plates are always moving. Moving slowly, but always moving.
The change in the position of a gene on a chromosome is called a?
The change in the position of a gene on a chromosome is called a mutation or a chromosomal rearrangement. This change can result in alterations to the structure or function of the gene, leading to different traits or diseases.
Homologous chromosomes is terms of the number of genes and the type of genes they have?
Homologous chromosomes are pairs of chromosomes (one from the female and one from the male), each of which contains genes which correspond to the genes on the other chromosome in the pair. For example, if a chromosome contains a gene for eye color, the corresponding chromosome will also have a gene for eye color in the same place.
When chromosome pairs separate into different sex cells does the alleles genes stay together?
During meiosis exchange of chromatid takes place by crossing over among the homologous chromosomes and chromatids of two chromosomes facing each other are involved in crossing over. Thus 50% of the gametes formed have new arrangement of alleles and rest 50% remain like those of parent cells.
List these in order from smallest to largest chromosome gene cell?
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
Where on the X chromosome does Fragile X take place?
Fragile X is a result of a mutation in the FMR1 gene on the X chromosome.
