Answer:
Explanation:
Let "XB
" represents the dominant allele for no baldness
and let "Xb
" represents the recessive premature male-pattern baldness
Genotype of affected male is Xb
Y
Genotype of heterozygous female XB Xb
Now when the above male and female are crossed, the following offspring are produced
Xb
Y * XB Xb
XB Xb, XB Y, Xb Xb, Xb
Y
Since, this Xb allele is only expressed in males, therefore females will not be affected by it
Hence, out of 4 offspring only one male offspring with "XbY" genotype will have premature baldness

Q2. We shouldn't wrap the dissected body into the original wrapper and give instructor to dispose it off.
<h3><u>Explanation:</u></h3>
Q1. A living organism has several characteristic factors like it has cells, the cell performs metabolic activities and the organism maintains a heredity along its progenies. The living organisms must have cells which leads them to enclose their cellular components inside it. It also must have a metabolic activity to metabolize nutrition into required energy. It also do have a heredity to continue the race it belongs to.
Q2. In the dissection class, after the experiment with dissected body is over, the dissected body needs to be wrapped in fresh polythene or other bags that should be pasted with biohazard stickers and should be eliminated into specific containers that contains other biohazard wastes. The instruments must be washed thoroughly with some antiseptic and soap. The hand gloves should also be dumped within the biohazard containers wrapped in proper bags.
