The genes involved in albinism are not linked. Gene mapping enables the localization of different genes on specific chromosomes.
Gene mapping refers to the genetic techniques used to establish the locations of specific genes on the chromosomes.
Moreover, a karyotype is a preparation of the set of condensed chromosomes in the metaphase stage, which are ordered according to their length.
In this case, it is possible to conclude that the four genes involved in albinism are not linked because they are found on different chromosomes (chromosomes 11, 15, 9 and 5).
Since albinism is passed from parents to offspring in an autosomal recessive inheritance pattern, a person can receive this trait by receiving two copies (one of each parent) for the four mutated genes involved in albinism.

(B) The opposite is true, too - when genes from a goat are inserted into a spider's genome, the spider produces goats' milk instead of silk.
(C) The proteins in goats' milk and spiders' silk have the same amino acid sequence
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
(E)The processes of transcription and translation in the cells of spiders and goats produce exactly the same proteins anyway.
Answer:
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
Explanation:
The genetic information present in the spider DNA can be inserted, transcribed and translated using similar machineries to that present in spiders. This produces the same protein, but the protein is likely processed and exported differently, meaning it plays different roles in each organism.
This is true for lots of scenarios, scientists frequently insert human genes into mice, and even cells in culture!
