Answer:
3
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.
Each chromosome has 46 in mitosis whereas meiosis has 23 pairs from each gametes (egg cells and sperm) from the parents which are called daughter cells so the answer is 23 and 23 one from the mother and the other from the father
A nurse suspects that the IV line through which Doxorubicin (adriamycin) is infusing has infiltrated. The nurse has discontinued the IV site.
The nurse should IMMEDIATELY APPLY ICE PACK TO THAT AREA. Ice pack helps to reduce the absorption of the drug doxorubicin and thus minimize the its effect.
