Which process of genetic recombination involves genes from both parents?
crossing over
independent assortment
fertilization
tetrad formation

The right answer is fertilization.

Fertilization is the stage of sexual reproduction consisting of gamete fusion, usually a male gamete and a female gamete into a single cell called zygote.

Fertilization allows the passage of two haploid cells, ie the gametes, into a diploid cell which is the zygote.

There are two types of genetic recombination: Intrachromosomal and interchromosomal.

Inter-chromosomal recombination takes place during meiosis, anaphase or when the cell separates in two, there is a random separation of chromosomes. The last stage of genetic mixing is fertilization: the chance encounter of gametes. It multiplies even more possibilities, in our example 8 million × 8 million = 64 000 billion.

the right answer is fertilization.
