Answer:
The frequency of recessive allele should be 0.30.
Explanation:
According to Hardy-Weinberg equilibrium, sum of both dominant allele frequency (p) and recessive allele frequency (q) should be equal to 1 (p+q = 1).
Brown hair = dominant (p)
white hair = recessive (q)
49% mice are brown hair
so dominant genotype frequency = 0.49
According to Hardy-Weinberg principle, square root of the genotype (homozygous) is equal to allele frequency.
√p =√0.49 = 0.70
The dominant allele frequency is 0.7
Now, by this value we can find the recessive allele frequency by
p + q = 1
1 - 0.7 = 0.3
So, the recessive allele (white hair mice) frequency is 0.30.

erosion is caused physically by earthquakes and stuff...hope this helps:))
nondisjunction is the answer. hope it helps
We have that there are 5 main tissue types in most vertebrates: epithelial, connective, nervous and muscle tissue. It is clear that muscle tissue helps the movement of various parts of the body and it is not dound in the skin. Also, interstitial tissue is the name with which we refer to extracellular fluids like blood plasma and thus this is wrong too (sweat is not a type of tissue). Nervous tissue is also deep under the skin. Connective tissue is the tissue that connects other types of tissues with the bones etc.; for example there is conenctive tissue in the brain. Finally, the correct answer is epithelial; they form the outermost layers of our cell structure and they serve to protect the rest of the tissue as well as provide us with sensations from the outside.
