Question

You are studying the inheritance of two characters of the komodo dragon. One
character is for a forked tongue (F). The other character is for sharp claws (S).
You have determined that both characters are dependent on a single gene and
there is a dominant allele (D or S) or a recessive allele (f or s). In your
experiment, you breed a double heterozygous male (FfSs) with a double
heterozygous female (FfSs). Quantification of the offspring shows you end up
with:

297 offspring with forked tongues and sharp claws
103 offspring with normal tongues and dull claws

What is the most likely explanation for this?
A) The genes for forked tongue and sharp claws are on the same
chromosome and close together
B) The genes for forked tongue and sharp claws are on different
chromosomes
C) The genes for forged tongue and sharp claws are on the X chromosome
D) The genes for forked tongue and sharp claws are on the same
chromosome and far apart

(Answer is A, please explain reasoning, punnet square)
