If a pure-breeding long-tail cat (LL) is crossed with a pure-breeding cat with no tail (rumpy, ll) , and a cat with a short tail (stumpy) is produced, the simplest explanation is a(n) ____ gene.

A) mutated
B) X-linked
C) incompletely dominant
D) lethal
E) pleiotropic

Question

llama gaming · Accepted Answer

Final Answer : C, Explanation :  This is most likely an example of incomplete dominance, where the LL allele for long-tails is not completely dominant over the ll allele for no tails, resulting in an intermediate phenotype of a short tail in the stumpy offspring. The other choices are not as likely explanations: A) mutated gene implies a random change in genetic material rather than a normal genetic inheritance pattern; B) X-linked genes are not probable in this scenario as tail length is not linked to sex chromosomes; D) lethal genes would not produce an offspring; and E) pleiotropic genes would have multiple effects on different traits, rather than just affecting tail length.
