<span>Answer:
TT=90
Tt=420
tt= 490
When there is 2 type of allele, there will be 3 possible genotypes: homozygous dominant, heterozygous, homozygous recessive. Dominant phenotype will be expressed for </span>homozygous dominant and heterozygous. That mean, the number of homozygous would be:
TT+Tt= 510
total population= TT + Tt + tt
1000= 510 + tt
tt=490
The frequency of recessive allele would be:
t= √(490/1000)= √0.49= 0.7
After that, you can find the frequency of the dominant allele
T+t= 1
T+0.7=1
T=0.3
Using both frequency, you can find the number of homozygous dominant (TT) and heterozygous (Tt) population
TT= 0.3 *0.3 * 1000 individuals = 90 individuals
Tt= 2 * 0.3 * 0.7 * 1000 <span>individuals</span>= 420 individuals
C.Atomic number have the same period
Answer:
Sedimentary Rock
Explanation:
Sedimentary rocks are formed from pieces of sediments or other existing organic matter or rock.
The sedimentary rock formation process begins with weathering which involves the breakdown of the sediments into small fragments. The next process is erosion, where water like the Nile River carries them to other places - in this case, the Ocean.
Over time, the sediments settle and become compressed as more sediments are deposited on top of them.
This leads to the formation of Sedimentary Rocks.
