is known as chromosomal translocation. This process can lead to genetic disorders if it disrupts the normal function of genes located on the chromosomes involved. Chromosomal translocations can be balanced, in which case they may have no noticeable effect, or unbalanced, which can result in various health issues.

Crossing-over is the exchange of reciprocal segments of DNA between homologous chromosomes true or false?
True. Crossing-over occurs during meiosis when homologous chromosomes exchange segments of DNA, resulting in genetic recombination and increasing genetic diversity in offspring.
In meiosis what is crossing over?
Crossing over is the process in meiosis where homologous chromosomes exchange genetic material. It occurs during prophase I of meiosis I and helps to increase genetic variation by mixing up the alleles on the chromosomes.
How does meiosis introduce genetic variation in to offspring?
Meiosis produces gametes which then go on to participate in sexual reproduction. Sexual reproduction combines the genetic material of the two parents - therefore creating variation.
What is the process in which homologous pairs of chromosomes separate and move apart is known as?
The process in which homologous pairs of chromosomes separate and move apart is known as meiosis. Meiosis is a type of cell division that results in the formation of reproductive cells (gametes) with half the number of chromosomes as the parent cell.
How does meiosis produce genetic variability?
There are three sources of genetic variation in meiosis: 1) Independent assortment = like shuffling a deck of cards and dealing out half the deck 2) Crossing over = homologous chromosomes swap parts, making new combinations 3) Random fertilization = only one sperm cell makes it into the egg
Crossing-over is the exchange of reciprocal segments of DNA between homologous chromosomes true or false?
True. Crossing-over occurs during meiosis when homologous chromosomes exchange segments of DNA, resulting in genetic recombination and increasing genetic diversity in offspring.
What is the process where parts of two homologous chromosomes switch places?
The process where parts of two homologous chromosomes switch places is called genetic recombination. This process can occur during meiosis when homologous chromosomes pair up and exchange segments of DNA, leading to genetic diversity in offspring.
What term is applied to the exchange of parts that may occur between pairs of chromosomes in the early stages of meiosis?
This process is known as crossing over. Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis, resulting in genetic variation among offspring.
How do sister chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
What is the difference between translocation and nondisjunction?
Nondisjunction is when a Chromosome is unable to separate correctly during cell devision. Translocation (In Chromosomes) is when an abnormality is caused by the rearrangement of parts between non-homologous Chromosomes.
In meiosis what is crossing over?
Crossing over is the process in meiosis where homologous chromosomes exchange genetic material. It occurs during prophase I of meiosis I and helps to increase genetic variation by mixing up the alleles on the chromosomes.
What is a chiasmata?
it is the part on the homologous chromosome that holds the two together once they have crossed over. the point where two homologous non-sister chromatids exchange genetic material during chromosomal crossover during meiosis
What crosses over during crossing over?
Each chromatid can synapse with any one it want/chooses.
What is meant by '' crossing over'' in terms of cells in your body?
Crossing over refers to the exchange of genetic material between homologous chromosomes during meiosis. This process increases genetic diversity by creating new combinations of genes, leading to unique traits in offspring. It helps in the formation of gametes with genetic variation.
What is it called when two chromosomes exchange parts?
mutagenesis occurs
Suppose your looking through a microscope and you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15?
An exchange of chromosome segments is called a translocation. In genetics, it refers to a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.
Body parts similar in origin and structure are what?
homologous
