How did African American slaves physically look?
African American slaves displayed a range of physical traits reflecting their diverse African ancestries, as well as factors such as intermixing with other populations in the Americas. They had varying skin tones, facial features, and body types. Over time, genetic exchange and adaptation led to unique phenotypes among African American descendants.
What is the genetic mechanism that may have been responsible for the base sequence changes between humans and gorillas?
Many genetic changes happened. One involved the joining of two "ape" chromosomes (they have 24 pairs of chromosomes) end to end to make human chromosome #1 (we have 23 pairs of chromosomes, but still have about the same amount of genetic material). This would have made it impossible for the "new" humans to successfully breed with their most recent prehuman ancestors, even though both peoples probably had identical appearance and lived together for several generations of both.
How is Neanderthal and modern man were similar in all?
Neanderthals and modern humans shared some similarities in aspects like tool use, social behavior, and symbolic expression. Both groups also had similar cognitive abilities, with evidence of complex thinking and problem-solving. Additionally, genetic studies have shown limited interbreeding between Neanderthals and early modern humans, further indicating similarities between the two groups.
What continent did the first human live on?
The first humans are believed to have originated in Africa. Evidence from archaeological and genetic studies suggest that early humans, known as Homo sapiens, evolved on the African continent before spreading to other parts of the world.
What are the four forces of human evolution?
The four forces of human evolution are mutation, genetic drift, gene flow, and natural selection. Mutation introduces new genetic variations, genetic drift refers to random changes in gene frequencies within a population, gene flow involves the transfer of genetic material between populations, and natural selection is the process by which certain traits become more common in a population due to their advantage for survival and reproduction.
What is difference between genetic screening and genetic counseling?
because u suck give me an answer and stop what you are doing
Which of the following is the most predictable outcome of increased gene flow between two populations?
decreases genetic difference between two populations
What is the difference between crossover and mutation in genetic algorithm?
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
How do you tell the difference between look alike dog breeds?
Genetic DNA testing
What the average genetic difference between any two humans?
Humans share about 99.5% of their genetic material, leading to an average genetic difference of 0.5% between any two individuals. This small percentage accounts for variations in traits such as eye color, height, and susceptibility to diseases among individuals.
What is the percentage of genetic difference between male and female humans?
There is only a small percentage of genetic difference between male and female humans, estimated to be around 0.1%. The majority of genes are shared between males and females, with the differences mainly located on the sex chromosomes (X and Y).
How can you tell the difference between male and female"?
The difference between male and female can be determined by physical characteristics such as reproductive organs, secondary sexual characteristics, and genetic makeup.
What is the difference between light and dark guppy fry?
There is only a genetic colour difference. Some are lighter or darker than others.
What is the difference between mutation and variation?
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
What is the difference between the location of the genetic material in the bacterium and in the lining of the intestine?
The bactirums genectic material is in the cytoplasm
What is the difference between AIDS and SCIDS?
scid is a genetic disorder while aids is caused by hiv virus
What information can be obtained from a genetic distance chart?
A genetic distance chart can provide information about the degree of genetic similarity or difference between different individuals or populations. It can help researchers understand the evolutionary relationships and genetic diversity among organisms.
