Answer:

The inheritance pattern is of sex-linked

Explanation:

Sex-linked traits are traits that are controlled by genes which are located on the sex chromosomes. Superscripts of the X or Y chromosome are written as the alleles for sex-linked traits chromosome.

In this case, since all of the male offspring have long tail fins, and none of the females possess the trait. Mating two of the F1 fish fails to produce females with the trait. The sex-linked gene that is on the Y chromosome and is possessed only by males is the type of inheritance pattern that occurs here because after mating the two F1 fish no female produced possess the trait.

Answer:

The inheritance pattern is of sex linked

Explanation

Genes that are carried by either sex chromosome are said to be sex linked. Men normally have an X and a Y combination of sex chromosomes, while women have two X's. Since only men inherit Y chromosomes, they are the only ones to inherit Y linked traits.
