Answer #1

Statement (a) is false because segregation of alleles occurs in meiosis, not in mitosis.

According to the Law of Segregation, every individual/organism has to alleles/trait which segregates or separate during meiosis.

In mitosis, segregation of chromosomes takes place, not segregation of alleles.

Option-b Yes, the genetic makeup of an organism constitutes its genotype.

Option-c Yes, genes are composed of segments of DNA.

Option-d Yes, the expressed physical traits of an organism are called its phenotype like colour,height etc.
