Broad palm with single palm crease is visible in a person suffering from-
1 Down’s syndrome
2 Turner’s syndrome
3 Klinefelter’s syndrome
4 Thalassemia
Explanation:
Down’s syndrome is caused by an additional copy of chromosome number 21. Its symptoms include– 1. Broad palm with characteristic palm crease

Autosomic trisomy condition is seen in
1 Turner’s syndrome
2 Klinefelter’s syndrome
3 Down’s syndrome
4 Both (2) & (3)
Explanation:
Down’s Syndrome : The cause of this genetic disorder is the presence of an additional copy of the chromosome number 21 (trisomy of 21)
BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

Down's syndrome is an example for:
1 Aneuploidy of sex chromosome
2 Aneuploidy of autosome
3 Syndrome caused due to gene mutation
4 Loss of one sex chromosome from the diploid set
Explanation:
An aneuploidy organism or cell is the one having a chromosome number that is not an exact multiple of the monoploid (n) with one genome. A trisomy is a condition in which an individual has inherited an extra chromosome, resulting in three copies of a particular chromosome instead of the usual two copies. Therefore, the individual would have 47 instead of 46 chromosomes. The presence of an extra copy of chromosome 21 leads to Down syndrome.
