An unpredicted change in genetic material between two chromosomes is known as a chromosomal mutation, which can include deletions, duplications, inversions, or translocations. These alterations can occur due to errors during DNA replication, exposure to mutagens, or environmental factors. Such changes can lead to significant biological consequences, including genetic disorders or cancer, depending on the genes affected and the nature of the mutation.
What else can I help you with?
When corresponding portions of chromatids on two homologous chromosomes change places what has occured?
This is called genetic recombination or crossing over. It results in the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic diversity in offspring.
What two ways can an organism's genotype change?
To put this answer as simply as possible, an organism's genotype can change due to either a random mutation in the DNA/chromosomes or the insertion of DNA from one organism into the DNA of another organism.
A change in the DNA or the chromosmes is called a what?
A change in the DNA or chromosomes is called a mutation. Mutations can occur in various forms, including point mutations, deletions, insertions, and duplications, and they can affect a single nucleotide or larger segments of genetic material. Some mutations can lead to genetic disorders or contribute to the evolution of species, while others may have no noticeable effect.
What is the difference between mutation and genetic recombination?
Mutations are random nucleotide alterations such as copying errors or changes induced by external mutagens. In contrast, genetic recombination is performed by the cell during the preparation of gametes (sperm, egg, pollen) which are used for sexual reproduction
Any permanent change in the genetic material of a cell is called?
mutations

This is called genetic recombination or crossing over. It results in the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic diversity in offspring.
What is a change in an organism's genetic material?
A mutation.
How many people use genetic testing?
30% of people or doctors use genetic testing because of the change in chromosomes
What is the permanent change in the genetic material of a cell?
A mutation
What is the definiton of mutation?
A change in the genetic material of an organism.
What is the difference between crossover and mutation in genetic algorithm?
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
What genetic material are called mutations?
Sudden genetic change in the DNA of an organism called mutations.
How does crossing over change the genetic material of chromatids?
During crossing-over, the genetic material from homologous chromosomes is swapped. This leads to a recombination of the genes. Simple example: Originally - ABCD alleles on one and abcd on the other. After crossing over - ABCd and abcD This creates offspring with non-parental phenotypes (traits), which are known as recombinants.
