What type of reproduction shuffles the genes

Sexual reproduction

Explanation:

Reproduction, the process of giving birth to new organisms is of two types;

Sexual reproduction involves the fusion of male and female gametes which gives rise to a zygote that eventually grows to become a new organism. These gametes are produced through meiotic cell division or gametogenesis.

In the early stage of this meiosis, homologous chromosomes pair up to form a tetrad and exchange of chromosomal segments take place between non-sister chromatids in a process known as crossing over.

Crossing over results in genetic recombination or gene reshuffling and ensures that daughter cells/gametes are genetically different from their parent cells.

Asexual reproduction involves the production of new organisms directly from the parent. The new organisms inherit the genes of the parents directly as there is no mechanism for genetic reshuffling.

Hence, the answer is sexual reproduction.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
