Bryologist (a scientist that studies mosses, and their allies) gives a lecture to your biology class. In her lecture, she makes a reference to fern reproduction. She says, "Fern spores germinate into .

Fern spore germinates into prothallus.

Explanation:

Ferns are members of phylum pteridophyta, the vascular cryptogams.

These are first land plants which are known to have a distinct conducting system of xylem and phloem.

They reproduce by forming spores that germinates into a heart shaped gametophyte.

The gametophyte of the fern is called prothallus.

The heart shaped gametophyte has root like structure called rhizoids.

These rhizoids anchor the gametophyte to the substratum.

your answer is rna to the question.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
