10.The genotype of an individual refers toa.results in an egg only.
Solution
1.Mitosis :c.results in a daughter cell that has the exact copy of the chromosomes of its parent.
Reason: Mitosis results in two identical daughter cells with same number of chromosomes as that
of parent cell.
2.Meiosis: d.haploid cells are produced from a single diploid cell.
Reason:Form a single dipolid cell, four haploid cells are formed.
3.Homologous chromosomes: c. come in pairs.
Reason: Homologous chromosomes means one from father and one from mother.So they come
in pairs.
4.Chromosomes are :a.replicated during cell division.
Reason: Chromosome replication takes place in mitosis.
5.Which of the following is true of mitosis?a.Mitosis produces identical daughter cells.
Reason: Mitosis results in two identical daughter cells with same number of chromosomes as that
of parent cell.
6.The phenotype of an individual refers to :d.its visible characteristics.
Reason:The observed characteristics of individual is known as phenotype.
7.Chromosomes are contained in :d.the nuclei of eukaryotes.
Reason: It is in the nucleus of eukaryotes that chromosomes are contained.
8.In diploid organisms :d.chromosomes occur in homologous pairs.
Reason: Homologous chromosomes means one from father and one from mother.So they come
in pairs.
9.Gametes : a.are the sex cells, or eggs and sperm.
Reason:Gametes are male or female sex cells.
10.The genotype of an individual refers to :c.the number of chromosomes in its body cells.
Reason:Genotype refers to genetic constitution of an individual and so refers to the number of
chromosomes in its body cells..
