Researchers studying blind cave fish that lack eyes found that crossing two pure-bred fish from the same cave gave only blind progeny. However, when they crosses two pure-bred cave fish from separate caves, all the progeny were able to see. From this result, they can conclude about the mutations which cause blindness in those cave fish in different caves are:

A. Located in separate genes
B. Display epistasis where one gene masks another
C. Located in the same gene
D. Located in two separate genes that must be right next to each other on the same chromosome
E. Form an allelic series in the same gene

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
