The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
<h3>What is a recessive phenotype?</h3>
A recessive phenotype is a phenotype which expresses the recessive trait of a gene.
The recessive phenotype is always h0m0zygous for that triat to be expressed.
In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:
where;
- p^2 is the h0m0zygous dominant phenotype frequency
- 2pq is the heterozygous phenotype frequency
- q^2 is the h0m0zygous recessive phenotype frequency
Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Explanation:
Male ; EeHh
Female ; EeHh
Then,
possible gametes for each = EH / Eh / eH / eh
where,
EH Eh eH eh
EH EEHH EEHh EeHH EeHh
<em> One eye One eye One eye One eye</em>
<em> One horn One horn One horn One horn</em>
<em />
Eh EEHh EEhh EeHh Eehh
<em>One eye </em><em>One eye</em><em> One eye </em><em>One eye</em><em> </em>
<em>One horn </em><em>Two horn</em><em> One horn </em><em>Two horn</em>
eH EeHH EeHh eeHH eeHh
<em>One eye One eye </em><u><em>Two eye</em></u><em> </em><u><em>Two eye </em></u>
<em>One horn One horn </em><u><em>One horn</em></u><em> </em><u><em>One horn</em></u><em> </em>
eh EeHh Eehh eeHh eehh
<em>One eye </em><em> One eye </em><em> </em><u><em>Two eye</em></u><em> </em><u><em> Two eye </em></u>
<em> One horn </em><em>Two horn </em><em> </em><u><em>One horn</em></u><em> </em><u><em>Two horn </em></u>
<u><em /></u>
Therefore,
One eye, one horn:One eye, two horn:<u>Two eye, one horn</u>:Two eye,two horn
is,
9 : 3 : <em><u>3 </u></em>: 1
This ration proves that the above working is correct and is dihybrid cross.

Answer:
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.
