I would like to say b but im pretty sure its c hope this helps
Answer:
Option E, Purple and long
Explanation:
Let the allele for red-flowered plant be "R" and allele for white -flowered plant be "r"
Allele for long radish be "L" and oval radish be "l"
Given -
A cross between a red-flowered plant (RR) and a white-flowered plant (rr)yields all-purple offspring (Rr)
And
Long is a dominant trait
Cross is carried out between true-breeding red long radishes (RRLL) are crossed with true-breeding white oval radishes (rrll)
The gametes for the two parents would b e
RL, RL , RL, RL
rl, rl, rl, rl
Thus, genotype of offspring would be "RrLl"
So all the offspring would be "Purple long"
Hence , option E is correct
Answer:
Indicator species, organism—often a microorganism or a plant—that serves as a measure of the environmental conditions that exist in a given locale. ... For example, greasewood indicates saline soil; mosses often indicate acid soil. Tubifex worms indicate oxygen-poor and stagnant water unfit to drink.
