Answer:
Phenotype genotype Number of individuals
Red RR 245
Pink Rr 210
White rr 45
Number of alleles in total
R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency
r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency
Predict (Hardy Weinberg) genotype frequencies=
p^2 + 2pq + q^2 = 1
p= 0.7
q=0.3
0.49 + 0.42 + 0.9 =1
According Punnett Squares in F1 we have=
Rr* rr = Rr 50% and rr 50%
I believe the correct answer is A) Silurian period occurred before the Neogene era, because the other answer are wrong.
Hadean eon ended before Silurian period.
Mesozoic and Permian era were after Silurian period.
The CNS are lined by ependymal cells. Ependymal cells are epithelial cells that monitor the composition of cerebrospinal fluid (CSF)
Answer:
The exchange of chromosome segment between non-homologous chromosomes is called translocation.
It is of two types:
There is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.
- Non- reciprocal translocation
A part of chromosome is translocated from one non-homologous chromosomes to other so that one chromosome becomes deficient and another non-homologous chromosome gains the piece of chromosome and becomes long.
Hope this helps...
Good luck on your assignment..
