Explanation / Answer

4 . Aneupliody 2n+1 ; Downs syndrome ,trisomy 21 , aneupliody 2n-1 ; turners syndrome where one X chromosome is missing .

5. effect of mother age aneupliody ; aneupliody increases with the increase with the mother age .

6.question is not visible

7. turners syndrome is caused by the missing or incomplete chromosome ,X chromosomes invoved in the growth and sexual development . so girls with missing X chromosome will lead to the incomplete developmenty of sexual charechterstic . turners syndrome is caused mainly due to non disjunction of the chromosomes ,when sperm with no X chromosomes unites with normal egg there will be missing of one chromosome in the embryo.

8. klinflinters syndrome ; it consists of two or more X chromosomes in males ,primary feature is sterility . the extra chromosome is retained because of the non disjunction of the chromosome .sperms will XY chromosomes or two XX chromosomes ,when there is no nondisjunction fertilisation lead to produce XXY offspring .

9. mosiacism is the syndrome where the presence of the two or more gentotypes in a single fertilized egg . it may be due to anaphase lag ,non disjuction , it may lead to somatic mosiacism

10 allotetrapliody ,it has chromosomes set that is 4 times more than that of hapliod organism ,the chromosomal sets parents are also present in gamates. autoterapliody, it has 4 copies of single genome s belong to the same individual

11. they are sterile as the lack chromosomes homologous chromosomes pairing during the meiosis .it is the association of the three chromosomes

13. mosiac digita 46 XX 5p deletion it is type of moasiacism syndrome ,chromosomal abnormality

question 6 and 12 are not visible properly
