What effects does union of haploids in fertilization have on genetic diversity?
Fertilization is random and the haploids are male and female gametes, sperm and eggs. So, genetic diversity is enhanced greatly because random fertilization comes after the independent orientation of male and female chromosomes plus crossing over in meiosis. So, statistically speaking, there are myriad variations that can come out of haploid random fertilization and so great genetic diversity is also enhanced here.
Why reducing biodiversity can lead to new problems?
Reducing biodiversity of a population can result in a loss of allele and reduced overall fitness, ultimately resulting in a decrease in genetic diversity. This reduced population is now vulnerable to diseases due to reduced biodiversity (e.g. Great Irish Famine).
How does sexual reproduction lead to natural selection?
Because sexual reproduction produces new and unique combinations of maternal and paternal alleles in each offspring. That leads to a great diversity of individuals in the population. Natural selection can then act on the population to give some individuals greater fitness than others, leading to changes in the population over time. -love to help CR
What are two adaptation of sexual reproduction?
but the adaptations are gametes ( cells like the sperm and the egg which have to join together) and sexual organsIt causes genetic variation and allows for better survivability.
What are the four elements thought to make America great?
The four elements thought to make America great are freedom, democracy, opportunity, and diversity.
Which ecosystem has a better chance of surviving when environmental conditions chandge over a long period of time?
One with a great deal of genetic diversity.
What type of biodiversity does coral reef have?
Coral reefs have great genetic diversity, unparalleled and immense species diversity, and relatively low ecosystem diversity.

Do Organisms produced as a result of binary fission exhibit a great deal of genetic variation?
Organisms produced through binary fission do not exhibit a great deal of genetic variation because this process involves a single parent cell dividing into two identical daughter cells, meaning they have the same genetic information. However, mutations can occur during the process, leading to some genetic diversity.
What role does genetics play in the diversity of a species?
Genetic mutations overtime can have a great deal of effects on population over time, DNA can mutate to fight off certain disease's or they could even cause the human body not to be able to fight off certain disease's
How do scientists explain the great diversity of life on earth?
Scientists explain the great diversity of life on Earth through the process of evolution by natural selection. Over millions of years, organisms have evolved and adapted to different environments, leading to the wide variety of species we see today. Environmental factors, genetic variation, and natural selection all play a role in shaping the diversity of life on Earth.

How does crossing over increase genetic diversity?
Crossing over occurs during meiosis when homologous chromosomes exchange genetic material. This results in the shuffling of genes between chromosomes, creating new combinations of alleles. This process increases genetic diversity by producing offspring with unique genetic profiles.
Which factor contributed most to great Britain's control over India until after World War 2?
the diversity and lack of unity amoung the indian population
The great variety of possible gene combinations in a sexually reproducing species is due in part to the?
Recombination, or crossing over, is the process by which homologous chromosomes exchange genetic material during meiosis. This creates gametes with many different combinations of alleles, and is a major source of genetic variation in sexually reproducing species.
What are two adaptation of sexual reproduction?
