Why crossing over takes place?
Occurs during prophase I of meiosis (pachytene) in a process called synapsis. Crossover usually occurs when matching regions on matchingchromosomes break and then reconnect to the other chromosome. The value of crossing over is that each parent has a different daughter cell.
What are the strands of genetic material floating in a nucleus of a animal cell?
Strands of genetic material floating in the nucleus is chromatin. Cytoplasm is the part of the cell that is between the cell membrane and the nucleus.
How is genetics material combined between two parents?
During sexual reproduction male and female gametes are formed in the respective reproductive organs. The gametes are haploid having half the number of chromosomes found in the parent body cells. These chromosomes have the genetic material in the form of DNA. When a male gamete unites with a female gamete during fertilization, the chromosomes in the zygote get doubled. The homologous chromosomes get paired at the time of meiosis in these offsprings and get combined by crossing over.
Genetic exchange between two arms of a chromosome pair is more likely to occur if the distance between the genes is great It is called?
crossing over
What are small elements of genetic material found in some bacteria called?
Bacteria have chromosomes that are not located within a nucleus (they don't have a nucleus). Chromosomes are normally found associated together in an area of the cell. Bacteria also have small circles of DNA called plasmids, these can sometimes be transferred between cells
What is the exchange of genes between homologous pairs of chromosomes?
homologous chromosomes exchange alleles during crossing over.
Crossing-over is the exchange of reciprocal segments of DNA between homologous chromosomes true or false?
It's true that crossing over is the exchange of reciprocal DNA parts between homologous chromosomes.
What trem describes the exchange of genetic material between members of a homologous pair of chromosomes?
Crossing over during meiosis results in to exchange of genetic material between members of a homologous pair of chromosomes.
What process results in an exchange of genes between homologons chromosomes?
Crossing Over
The exchange of parts between non homologous chromosomes...?
Crossing Over
What exchange of genetic material between arms of homologous chromosomes?
When chromosomes cross over. (Chromal Crossover, I believe)
What happens chromosomes undergo crossing-over?
During meiosis, permutation.
What is the exchange of DNA between homologous chromosomes during pro phase of meiosis?
Crossing over or chromosomal crossover.
When occurs between nonsister chromatids genetic exchange between chromosomes provides new combinations of genes that are different from the parent cell?
crossing over
What term is applied to the exchange of parts that may occur between pairs of chromosomes in the early stages of meiosis?
Crossing over
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
Which part of chromosome exchange during meiosis centromere or telomere?
During meiosis, chromosome exchange occurs at the chiasmata, which are points of crossing over between non-sister chromatids. The exchange involves the exchange of genetic material between homologous chromosomes, not specifically at the centromere or telomere regions.
