A flowering plant obeys Mendelian genetics where the yellow flower is dominant over pink flowers. You are given a yellow flowering plant.
What type of plant would you use to perform a test-cross with this plant to determine its genotype?

a) True breeding yellow flowering plant
b) F1 generation plant
c) True breeding purple flowering plant
d) True breeding pink flowering plant

option D

Explanation:

This is to test for the genotype of an organism that shows the dominant phenotype for a particular trait trait. To perform a testcross in determining the genotype of a plant, a true breeding pink flowering plant is usually utilized.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
