He first step in solving this problem requires an examination of the possible genotypes of the parents. As stated color-blindness is a recessive linked trait. So the genotypes of the parents should be:

mother's genotype (normal vision but whose father was color blind) XNXn

She is a carrier because of her heterozygous condition. For the recessive gene to be expressed one must be homozygous for it.

father's genotype (color blind) XnY

1. Explain using diagram how monomers are arranged in Thermoplastic and Thermosettingplastics.

Romashka [77]

Explanation:

In thermoplastics, the arrangement of monomeric units is linear and in thermosetting plastics, it is cross-linked. Thermoplastics are usually soft, weak and less brittle, so can get soften on heating and stiffen on cooling. They can be melted, remoulded and recycled easily.
