Which of Mendel's laws cannot be observed in a monohybrid cross?
Mendelâ??s Law of Independent Assortment cannot be observed in a monohybrid cross. This is because you need to be able to observe two or more pairs of alleles in order to see this law in action as it describes how multiple pairs of alleles segregate independently of each other.
When plants that are true breeding for different traits of a characteristic are crossed the trait observed in the first generation is called the?
dominant
What did Robert Hooke discover with cells?
He observed a piece of cork under the microscope he invented. He noticed the small chambers which resembled the rooms monks lived in called 'cells'.
What technology did Gregor Mendel use for his pea plant experiments?
Gregor Mendel didn't really use any technology. He basically observed the pea plants traits generation after generation, and the outcome of the same experiment repeated.
What are the phenotype of the f2 generation that Mendel observed?
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).

The observed trait in the first generation?
Dominant trait
What or who disproved all atoms of a given element are the same?
Frederick Soddy in 1912 observed first radioactive isotopes and J.J. Thomson first stable isotopes in1913.
The trait observed in the first generation when parents that have different traits are bred?
A dominant trait.

What are large dark flat-areas found on the hemispherical surface facing the Earth called?
Large dark areas on the Moon are called "maria", Latin for "seas", because the ancients who observed the Moon with the naked eye thought that they resembled the seas that they were familiar with.

What is a sicentific theory?
A scientific theory provides an explanation of observed natural phenomena and predictions that can be tested by further experiments. These f]serve as the framework for organizing scientific knowldege. Theories are not proven or facts, these are just predictions and possible explanations. Theories can never be completey true, they can only be disproved.
