D Question 1 In a diploid organism, alleles of a gene are located on O non homologous chromosomes O sister chromatids O homologous chromosomes O the same chromosome 0.5 pts

Solution

1. The variant form of a gene is called as an allele. In diploid organisms, alleles of same locus either may be homozygous or heterozygous. Therefore, the alleles occur on sister chromatids. Option 2 is correct.

12. During meiosis two consecutive nuclear divisions take place and result in formation of 4 haploid daughter nuclei. The meiosis is carried out in series of events occurring at various stages. In the first stage (prophase I) the diploid nuclei containing chromosomes from as tetrads and are condensed. The synapsis and crossing over takes place to exchange the fragments between the chromosomes. Option 1 is correct.

13. Gametes of diploid organisms are haploid and should have one copy of every gene. Option 4 is correct.
