1) If a line of plants self pollinate for long enough, that line will become genetically uniform, or ....? ​
* ○ ​
Pure ○ ​
Purebred ○ ​
Organized ○ ​
Identical 2) If a purebred plant self pollinates, its offspring will ..... ​
* ○ ​
Share all of its characteristics. ○ ​
Share some of its characteristics. ○ ​
Share none of its characteristics. 3) Mendel selected Pea Plants to perform his experiments because of which of the following reason(s)? ​
* Check all that apply ○ ​
They reproduced quickly ○ ​
He could eat them after ○ ​
He could easily control them ○ ​
They had clear traits that allowed him to distinguish from one another ○ ​
He had a lot of them around his house 4) How many Pea Plant Traits did Mendel choose to observe? ​
* ○ ​
4 ○ ​
5 ○ ​
6 ○ ​
7 5) What did Mendel do before making his conclusion? ​
* ○ ​
He crossed 2 pea plants, one with white flowers and one with purple flowers and recorded his observations ○ ​
He crossed many purebred pea plants by hand for each trait and recorded his observations ○ ​
He planted tons of pea plants in a field and recorded his observations over 10 years ○ ​
He crossed several pea plants by hand and made guesses as to which traits he would see in their offspring 6) Mendel made 3 conclusions (2 of which were part of his Law of Segregation). What was his first conclusion not including the Law of Segregation.? ​
* ○ ​
Traits are inherited and can always be visible to the naked eye. ○ ​
Traits are mixed together if the parents do not express the same form of a trait. ○ ​
Traits are inherited as discrete units, which provided an explanation for individual traits that persisted without being blended or diluted. ○ ​
Traits could be expressed in only 2 ways. No more, no less. 7) What were the two parts of Mendel's Law of Segregation? ​
* Check all that apply ○ ​
Organisms donate only one copy of each gene in their gametes. Thus, the two copies of each gene segregate, or separate, during gamete formation. ○ ​
Organisms donate all of their genetic makeup to their offspring. Whether it is visible or not is another matter. ○ ​
Organisms are a perfect blend of both their parents. ○ ​
Organisms inherit two copies of each gene, one from each parent. 8) Please select the correct order of generations via the Indicators that Mendel developed. ​

* Select the correct definition ○ ​
Crossing with 2 traits ○ ​
Genetic Makeup ○ ​
Same alleles ○ ​
Different alleles 14) Dominant Allele ​
* Select the correct definition ○ ​
Both alleles (factors) for a trait are the same and dominant (AA) ○ ​
Genetic trait that is represented with a capital letter and will always show if it is present. ○ ​
The study of heredity or how those traits are inherited ○ ​
Uniting of the male and female gametes 15) Recessive Allele ​
* Select the correct definition ○ ​
Genetic trait that is represented with a capital letter and will always show if it is present. 1 ○ ​
Both alleles (factors) for a trait are the same and recessive (aa) ○ ​
The study of heredity or how those traits are inherited ○ ​
A trait that is masked by the dominant trait. Only apparent when two recessive alleles for the same characteristic are inherited.
