Explanation:
mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

</span>The percentage of mice that are homozygous
recessive: __36%_______
Let us assign the dominant allele (that of brown hair) letter R
while
We assign the recessive
allele (that of white hair) letter r
We then note down the
Hardy-Weinburg equation p2 + 2pq + q2 = 1
Brown fur population (p2
+ 2pq) = 64% = 0.64
White fur population (q2) = 36% = 0.36
Then we also remember that the frequencies of both allele
add up to 1 (p + q = 1);
Therefore q = ü.36
= 0.6
P = 1 – q = 1 – 0.6 = 0.4
The heterozygous population will be 2*0.6*0.4 = 0.48 = 48%
Homozygous domain population will therefore be (64% - 48%) =
16%

Answer:
By reducing the number of chromosomes in gametes to one-half of the diploid number (to the haploid number), fertilization will restore the diploid number of chromosomes when the gametes fuse.
Explanation: i just looked at my notes
also have a lovely day
Answer:
The chair is made of abiotic factors, such as plastic or wood that needed to be chopped down, and is thus dead. I am alive because I have living organisms and organs that help my body function and keep me alive.
