When winding an old clock, it is important not to overwind it. Overwinding occurs when the mainspring is almost fully wound, but the operator continues to turn the winding key. This causes the main spring to coil too tightly, and might even break it.

This paragraph best supports the statement that

#General Aptitude
  1. clocks have changed over the years.
  2. old-fashioned clocks become fragile with age.
  3. old-fashioned clocks were operated by an internal spring.
  4. overwinding clocks used to be a common mistake

Aneuploids may arise through nondisjunction, the failure of homologous chromosomes or sister chromatids to separate in meiosis. Following some statement are correct.

A)  Meiosis I non-disjunction leads to produce all gamete become aneuploidy

B) Meiosis II non-disjunction leads to produce half of gametes n+1 other half normal haploid

C) Meiosis I non-disjunction leads to produce half of gametes n+1 other half n-1

D) Either meiosis I or meiosis II non-disjunction leads to produce all aneuploidy gamete

Following is heterozygote for inversion?

Following some statement given for above abnormality?

A) There is a less probability of a crossover occurring within inversion region and producing an enviable cross over meiotic product.

B) Chromosomes that have engaged in crossing-over separate in the normal fashion, without the creation of a bridge

C) The crossover produces chromatids that contain duplication and a deletion for different parts of the chromosome results non viable gamete

D) Double cross over within inversion loop will be results all viable gamete of parental and recombinant
