Question

13. The diagram shows a 'normal' human body cell.
(a) In which part (A,B or C) would you find
the genetic information? Name the
organelle and give reason for your
answer.

(b) How would the genetic information be
different if this were a human egg cell?

(c) What is a gene? Suggest three examples
of characteristics controlled by genes in
humans​

Answer 1

Answer:

in part (c) genetic material will be present. it is nucleus.

if b is given as mitochondria (which i am not sure because of clarity of diagram), then it also has mitochondrial DNA.

The human egg cell will have one set of chromosomes i.e. Haploid set. (in a normal body cell we have two sets of chromosomes, i.e. diploid set).

gene - it is a particular segment of DNA which is responsible for the inheritance and expression of a character.

characters such as eye colour, widow's peak, rolling of tongue, skin colour, etc. are controlled by genes.
