What else can I help you with?
Based on his experiments Mendel concluded that each trait was controlled by two?
invisible "factors" - now called genes.
True or false Gregor Mendel concluded that the tall plants in the P generation passed the factor for tallness to the F1 generation?
True. Gregor Mendel concluded that the tall plants in the P generation passed the factor for tallness to the F1 generation based on his experiments with pea plants and his observations of phenotypic ratios.
What was the purpose of Mendel's experiments the dihybrid crosses?
He wanted to determine if traits affected each other, and concluded (based on his observations) that they did not. + To find out if traits could affect the inheritance of other traits. to determine if traits affected each other
What did Gregor Mendel reason from the existence of yellow and green seed colors?
Gregor Mendel reasoned that yellow seed color is dominant over green seed color based on his observation of the ratios of yellow to green seeds in his pea plant experiments. This led him to propose the concept of dominant and recessive traits in inheritance.
Is it possible to prove a hypothesis by conducting rigorously controlled experiments?
Rigorously controlled experiments can provide evidence to support or refute a hypothesis, but they cannot definitively prove a hypothesis. Scientific hypotheses are continually evaluated, refined, and occasionally rejected based on new evidence and further experimentation.

What is the purposes of Mendel's experiments with dihybrid crosses?
He wanted to determine if traits affected each other, and concluded (based on his observations) that they did not.Today we can't be that sure because Mendel had the luck to only observe traits on different chromosomes. But if two genes, which encode for the observed traits, lie on the same chromosome, maybe even in neighbouring regions, they have a higher chance to be passed on to the next generation together.

Why is Mendel important to science?
Gregor Mendel is known as the father of genetics. He observed that pea plants had certain characteristics that were dominant. He concluded by observing the traits of cross breeding different types of pea plants that traits such as height, flower color, and seed shape were determined by dominant factors. Since Mendel laid down the principles of inheritance based on his experiments on hybridization in pea plant, a systematic study in genetics started to explain many unanswered questions. Mendel's contribution was recognized and he is rightly been considered as father of genetics. Mendel's approach of mathematics in biological science led him to arrive at such conclusions.
Who concluded that all animals are made up of cells?
Theodor Schwann and Matthias Schleiden are credited with the Cell Theory, which states that all living organisms are composed of cells. They concluded this in the 19th century based on their observations and experiments with plant and animal tissues.
Who concluded that all elements contain electrons?
J.J. Thomson concluded that all elements contain electrons based on his discovery of the electron in 1897 through his experiments with cathode rays. This led to the development of the plum pudding model of the atom, in which electrons are embedded in a positively charged sphere representing the rest of the atom.
What did Gregor Mendel reason from the existence of yellow and green seed colors?
Gregor Mendel reasoned that yellow seed color is dominant over green seed color based on his observation of the ratios of yellow to green seeds in his pea plant experiments. This led him to propose the concept of dominant and recessive traits in inheritance.
When did Frederick Griffith discover transformation?
Frederick Griffith discovered Transformation doing lab experiments in the 1930's. He initially based his work of Gregor Mendel, the father of genetics, and discovered more as he experimented of lab mice.
Is it possible to prove a hypothesis by conducting rigorously controlled experiments?
Rigorously controlled experiments can provide evidence to support or refute a hypothesis, but they cannot definitively prove a hypothesis. Scientific hypotheses are continually evaluated, refined, and occasionally rejected based on new evidence and further experimentation.
Can you start a question with the word based?
Yes! For instance, you could write... "Based upon the evidence found, I concluded that ___________."
