Answer:
Species are adapted to their environments. By understanding the interactions within an ecosystem, scientists can develop an understand of how populations evolve (develop gradually) in response to their environment.
The answer to this question would be: alopecia areata
In this question, there is a certain area of the scalp that didn't have any hair. The best term to this condition would be alopecia areata.
There are a few reasons why a spot of baldness can appear. It can be caused by stress that inducing autoimmune disease. Before diagnosing a patient with this you must exclude the possibility of fungal infection as it can destroy the hair and make it look bald.
The soles of people’s feet have a greater concentration of sensory receptors because more people are ticklish on the bottoms of their feet than the backs of their necks. There are more neurons in your appendages especially the ends of them because they are the furthest from the brain. Getting a tattoo on your feet vs. the back of your neck hurts more as well, making the soles of your feet have the greater concentration.
<span>F- allele for freckles
f- </span><span>allele without freckles
1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
Their son would have a probability of 75% of being born with freckles.
2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).
