What else can I help you with?
What would occur if humans reproduced by parthenogenesis?
Humans are produced via sexual reproduction. That gives genetic diversity. You do not get such genetic diversity in case of the parthenogenesis. It is poor mode of reproduction.
Does humans ever have more then 46 chromosomes during their evolution?
Only in the case where there is a genetic deformity.
What are two processes that add to the genetic diversity of humans?
mutation and random mateing maybe not sure apex sucks anal
How many possible humans are there geneticaly?
There are approximately 7.8 billion humans on Earth, each with a unique combination of genetic material inherited from their parents. This genetic diversity is vast and virtually limitless due to the random nature of genetic recombination and mutations that occur during reproduction.
How can genetic variation help human and life?
Genetic variation is crucial for the survival and adaptability of species, including humans, as it provides a diverse pool of traits that can enhance resilience to environmental changes, diseases, and other challenges. It facilitates evolution by enabling populations to adapt over generations, leading to improved survival rates. Additionally, in humans, genetic diversity plays a key role in health and disease susceptibility, influencing responses to treatments and the effectiveness of medications. Ultimately, genetic variation is essential for the dynamic and changing needs of life on Earth.
It is believed that genetic drift was a factor in the diversity of humans?
true
What are the reasonable evaluations of evolution in humans today?
The reasonable evaluations of evolution in humans today suggest that genetic variations and natural selection continue to shape our species over time. Scientists study factors such as adaptation, genetic drift, and gene flow to understand how humans have evolved and continue to evolve. This ongoing process of evolution helps us better understand the diversity and complexity of the human species.

Do humans have more or less genetic variation than most species?
Humans have lower genetic variation compared to other species due to the bottleneck effect experienced in human evolution. This is because human populations are relatively small and have undergone significant reductions in genetic diversity.
How did the phenomenon of Neanderthal interbreeding with humans impact the genetic makeup of modern humans?
The interbreeding between Neanderthals and humans influenced the genetic diversity of modern humans. It introduced genetic variations that are still present in some populations today, contributing to our overall genetic makeup.
Example of genetic diversity?
The potato famine in Ireland is an example of genetic diversity. Instead of propagation from seed for genetic diversity, they propagated from existing potatoes, clones, and when a blight occurred it wiped out the food source for an entire population
Does humans ever have more then 46 chromosomes during their evolution?
Only in the case where there is a genetic deformity.
Why do humans have 23 chromosomes?
Humans have 23 pairs of chromosomes because this number allows for genetic diversity and proper cell division during reproduction.

What is a genetic bottleneck and are humans affected by one?
A population bottleneck (or genetic bottleneck) is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing. This reduces the genetic diversity of the population, and even if the population bounces back in size, it can often show evidence of the past bottleneck by lacking significant variation for its size. A good example is that of the cheetah, whose current population shows almost negligible variation. Humans are not currently experiencing any genetic bottlenecking because the population is increasing. However, there is evidence suggesting that the human population underwent one or more bottlenecks in the past, since its overall genetic diversity is relatively low for its size.
