Question

​In a cross between individuals of a species of tropical fish, all of the male offspring have long tail fins, and none of the females possess the trait. Mating two of the F​1 ​fish fails to produce females with the trait. What type of inheritance pattern is

Answer 1

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.

Answer 2

The inheritance pattern is of sex-linked

Step-by-step 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 F​1 ​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.
