Answer:
a. The maternal copy of UBE3A is expressed and the paternal copy is silenced.
Explanation:
When UBE3A chromosome is in neurons, paternal allele is silent and maternal allele is expressed in process of genomic imprinting. In some cases UBE3A is expressed from both paternal and maternal chromosomes. The paternal chromosome is blue whereas maternal chromosome is magenta.
Answer:
0.08
Explanation:
According to Hardy-Weinberg equilibrium, in absence of an evolutionary force allele frequencies in a population remain constant. In case of polyploid organisms, the formula for Hardy-Weinberg equilibrium is :
(p+q)^c = 1 where,
p = frequency of dominant allele
q = frequency of recessive allele
c = ploidy number
Here, the ploidy number is 4 since there are four chromosomes at a locus instead of the usual two.
f(C1)(C1) = 0.28
f(C2)(C2) = 0.72
Black rabbits = C1C1C1C1
Frequency of black rabbits= f(C1)(C1)*f(C1)(C1)
= 0.28 * 0.28
= 0.0784
= 0.08
For number 1 the first arrow is the cell wall, the second is the membrane, and the last arrow would be the cytoplasm
For number 2 they are in distilled water Bc they are remaining the same and not shrinking up
For three draw the cells smaller salt water sucks the water out of them
For four they get smaller because the salt has a higher concentration making the water leave the cell. Once water has left the cell begins to shrink
