Explanation: I did it on Edge 2020 and it was correct.
I would say they need to look to Linneaus System of Classification, because he devised the taxonomical system of class, order, phylum, species variety, etc.
The fraction of offspring with black coat color and straight fur is 9/16.
Explanation:
Information given:
black coat colour and straight fur - dominant genotype BBCC, BbCc
yellow coat colour and curly fur - recessive genotype bbcc
Both the traits are independently assorted. The fur colour and fur type is not present on the same chromosome and are not sex linked.
The genotype of the parents are:
BbCc X BbCc
Punnet square shows:
BC Bc bC bc
BC BBCC BBCc BbCC BbCc
Bc BBCc BBcc BbCc Bbcc
bC BbCC BbCc bbCC bbCc
bc BbCc Bbcc bbCc bbcc
9 BLACK STRAIGHT
3 BLACK CURLY
3 YELLOW STRAIGHT
1 YELLOW CURLY
9/16 is the fraction of progeny to be black coat colour and straight fur.
