Answer to Question #300659 in Genetics for claire yeboah

Question

f) The pair of cats produce in their first litter together the following kittens: 

3 tortoiseshell short fur females, 2 tortoiseshell long fur females, 3 ginger short fur males, and 1 ginger long fur male.

From this information only (no genetic diagrams required), what evidence can you use to deduce the genetic identity of the parent cats?                                                       (4 marks)

 

 

 

g) Having identified the genetic identity of the parent cats, fully proof your answer to show the simultaneous transmission of the two genes involved with this family of cats, with the use of genetic diagrams and summaries as required. (Hint: you are only required to show the simultaneous transmission from the P to F₁ generations)     

Answer 1

f) In each pair of chromosomes,a cat inherited one chromosome from each parent. Therefore 19 chromosomes are inherited from the mother and 19 chromosomes from the father.Each chromosome caries distinct variant of genes.The expression of the genes depend on which alleles the cat carries for each Gene.

g) Inheritance has taken place; the passing of traits to offsprings from parents.The traits are passed through asexual or sexual reproduction.The offsprings receives the genetic material from the parents.
