'which helps to ensure that genetic diversity will be maintained?

Answer 1

Genetic diversity helps biodiversity even exist. Let's say that all birds had exactly the same DNA. There would be neither genetic diversity or biodiversity, meaning all birds would be the same everywhere. However, if we say that there are 5 different species of birds with slightly different DNA, there would a more diverse ecosystem, biome, etc.

Genetic diversity is also important because if all birds had the same exact DNA, and then a plague came along and killed the birds within a certain species, there would be no more birds, messing up all of the ecosystems, biomes, etc. However, if most birds have different DNA, and a plague came and killed the birds within the certain species, only one species out of many would be extinct, while the rest live on to maintain their ecosystems, biomes, etc.

Answer 2

Maintaining genetic diversity is important for the long-term survival of a population or species, as it increases their ability to adapt to environmental changes and reduces the risk of genetic disorders. Factors that help ensure genetic diversity include reproduction between genetically distinct individuals, limiting inbreeding, and preserving natural habitats to allow for gene flow between populations.

Answer 3

three ways that genetic diversity is maintianed.

1. independent assortment

2. crossing over

3. genetic recombination

Answer 4

Crossing over in meiosis. Random fertilization in two gametes ( male sperm, female egg ) and the random way chromosomes line up in meiosis. To a lesser extent, mutation.
