Klinefelter's syndrome is represented by 44 autosomes + XXY. When an abnormal egg with XX chromosome is fertilized by a sperm carrying Y-chromosome a zygote having XXY sex chromosomes is formed. The resulting young one is an abnormal sterile male. The 44 autosome + XO condition is due to Turner's syndrome. Such females are sterile and have short stature, webbed neck, broad shield-shaped chest etc. Down's syndrome is due to trisomy of 21st pair of chromosome. It is characterised by moderate mental retardation, large tongue, short stature, stubby fingers, an enlarged liver and spleen. Colourblindness is an X-linked disease. The person suffering from this disease cannot differentiate between red and green colours. Erythrobalstosis-foetalis is caused due to Rh factor in child of Rh+man and Rh−woman.

What is the pattern of inheritance for polygenic trait?
With the help of given pedigree, find out the probability for the birth of a child having no disease and being a carrier (has the disease mutation in one allele of the gene) in $F_3$ generation. 
Genes $R$ and $Y$ follow independent assortment. If RRYY produce round yellow seeds and rryy produce wrinkled green seeds, what will be the phenotypic ratio of the F2 generation?
When a tall pea plant with round seeds was selfed, it produced the progeny of : (a) Tall plants with round seeds and (b) Tall plants with wrinkled seeds. Identify the genotype of the parent plant.
Given below are two statements: Statement I: Failure of segregation of chromatids during cell cycle resulting in the gain or loss of whole set of chromosome in an organism is known as aneuploidy. Statement II: Failure of cytokinesis after anaphase stage of cell division results in the gain or loss of a chromosome is called polyploidy. In the light of the above statements, choose the correct answer from the options given below:
