Does cell fusion count as genetic recombination, and how does genetic recombination occur?

If cells from different species are fused, it is technically called a heterologous fusion, even if it is a genetic recombination.

No, the truth is like sucrose dissolves in water, sucrose can be dissolved in water, but sucrose and water do not react, do not produce new substances, just a physical phenomenon;

The same is true for cell fusion, where a few cells become one, but the genes are not changed.

Genetic recombination is a metamorphosis.

Modern genetic engineering technology is a technology that implements genetic recombination according to artificial design in a test tube, also known as.

Recombinant DNA. The goal is to transfer a genetic gene from one individual cell to another individual intracellular DNA molecule with a different trait to cause genetic variation.

After the target gene from the donor is transferred to the recipient bacteria, the gene product can be expressed, so as to obtain products that are difficult to obtain by ordinary methods, such as insulin, interferon, hepatitis B vaccine, etc., which are mass-produced by genetic recombination with the corresponding gene with E. coli or yeast, that is, gene recombination. Appearance.

Yes variants, variants that can be heritable in high school organisms include genetic mutations, genetic recombination, and chromosomal variations. So genetic recombination is also a type of variation.

It's not genetic recombination, it's reproductive inheritance.

What is the process of genetic recombination.

The pollen of plants with genotype AABB: AB, AB, AB, AB.

The genotype is the pollen of the YY plant: y and y.

So, there are 6 different genotypes.

In the question, "only two cells are considered to be fused", indicating that these pollen are fused together.

1. If two pollen of the same genotype are fused, there are 6 species, namely aabb, aabb, aabb, aabb, yy, yy;

2. If the pollen of two different genotypes is fused, there are 6+8=14 species, (1) for the pollen produced by the AABB genotype and YY pollen, there will be six kinds of AABB, AABB, AABB, AABB, AABB, and YY;

2) For the pollen produced by the AAB genotype and the YY pollen, eight kinds of aby, aby, aby, aby, aby, aby, and aby, respectively;

Therefore, there should be 6+14=20 genotypes.

PS: Among the 20 kinds, although some genotypes are the same, the position of the gene on the chromosome is different, such as AAB, which can be combined by AB to AB, or by AB and AB, although the position of the gene on the chromosome is different in these two binding methods, but the genotype of the fused cell is the same, all are AABB

Non-allelic genes on homologous chromosomes are exchanged.
