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.

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:
