Answer:
Rr x rr
Explanation:
Let's say
RR is a tall plant.
Rr is tall
& rr is a small plant
The only genotypes you can get to make two tall and two short is if you use a hetero pair and a same ressesive (rr) genes.
I think it's electric force. Not 100% sure but I hope it's right.
The duplication of homeotic ( H o x ) genes has been significant in the evolution of animals because it <u>permitted </u><u>the </u><u>evolution </u><u>of novel forms</u>
<h3>What is the Hox genes and evolution?</h3>
Hox proteins are a family of transcription factors that have undergone extensive conservation. They were first identified in Drosophila for their crucial functions in regulating segmental identity along the antero-posterior (AP) axis.
The regionalization of the AP axis and changes in the expression patterns of these genes have been strongly correlated during the past 30 years across a wide range of evolutionarily distinct species, indicating that Hox genes have been essential in the evolution of new body plans within Bilateria.
Despite this extensive functional conservation and the significance of these genes for AP patterning, many important concerns about Hox biology remain.

Answer:
the difference between frog and grasshopper is that
frog is a small tailless amphibian of the order anura that typically hops or frog can be (offensive) a french person or frog can be a leather or fabric loop used to attach a sword or bayonet, or its scabbard, to a waist or shoulder belt
while grasshopper is a herbivorous insect of the order orthoptera noted for its ability to jump long distances.
frog is to hunt or trap frogs or frog can be to ornament or fasten a coat, etc with frogs or frog can be to unravel (a knitted garment).
