According to the passage, which of the following topics of study was the most crucial to his final analysis?
TEA [102]

Answer: The study of plant varieties.

Explanation:

This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.

Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.

He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.

algol [13]

Answer:

100% EE, 100% red eyes

Explanation:

For an organism, the genotype refers to the genetic characteristics of the organism while the phenotype refers to the physical characteristics of the organism.

The red eyes (E) is dominant while the white eyes (e) is recessive.

Since both parents are EE, the genotype of their offsprings would be EE, EE, EE, EE

That is: EE × EE = EE, EE, EE, EE

Hence the genotype is 100% EE.

Also, the phenotype is 100 red eyes.
