The percentage of plants that have the dominant RR is 50%.
According to Mendel, factors of inheritance called genes are located in the chromosomes. Genes usually occur in pairs called alleles. The genes in an allelic pair may be dominant or recessive. The dominant gene is always expressed while the recessive is only expressed in the absence of the dominant gene.
Using a Punnet square, we can see that the percentage of plants that have the dominant RR is 50%.

A There are no planes of weakness in its lattice structure
B It's not a naturally occurring substance
C It's too new to be a mineral
D It would not be hard enough
The reason why a new rock-like substance created in a laboratory would not be classified as a true mineral is because it does not meet one of the essential criteria for being considered a mineral: being a naturally occurring substance.
Minerals are formed naturally through geological processes over long periods of time. They are typically found in the Earth's crust or other natural environments. However, the substance created in a laboratory is artificially synthesized, meaning it is made by humans in a controlled setting rather than being formed naturally.
For example, if a scientist combines different chemical compounds in a lab and creates a rock-like substance, it may have similar physical properties to a mineral, such as hardness or color. However, since it was intentionally made by humans, it does not qualify as a true mineral.
Therefore, the correct answer is B: It's not a naturally occurring substance
Answer:
Negative feedback occurs when a system's output acts to reduce or dampen the processes that lead to the output of that system, resulting in less output. In general, negative feedback loops allow systems to self-stabilize. Negative feedback is a vital control mechanism for the body's homeostasis.
Answer:
A scientist needs to share his work with the scientific community in order for it to be recognized. The ways in which scientists can share their results are:
