Total questions: 10
Worksheet time: 5mins
Who is Gregor Mendel
an Austrian Monk from the mid 1800s who contributed to the study of Genetics
The scientist who discovered the structure of DNA
a British scientist who discovered penicillin
The scientist who used X-Ray Crystallography to shed light on the structure of DNA
What did Gregor Mendel study?
Mold Spores
Pea Plants
Sun Flowers
Rats
What did Mendel notice?
Most pea flowers were tall, and some were purple.
Most of the pea flowers were white, but a few were purple.
Most of the pea flowers were purple, but a few were white.
Most pea flowers were short, and some were white.
What was Mendel's first conclusion?
Pea plants were inheriting a pair of genetic instructions from both parents.
Pea plants were inheriting genetic instructions from their grandparents.
Pea plants were inheriting genetic instructions only from their maternal parent.
Pea plants were inheriting genetic instructions only from their paternal parent
What was Mendel's Second conclusion?
The allele (factor) for purple flowers was stronger, or more dominant, than the white allele (factor)
The allele (factor) for purple flowers were the same strength, equal dominance, to the white allele (factor)
The allele (factor) for purple flowers was weaker, or more recessive, than the white allele (factor)
The allele (factor) for white flowers was stronger, or more dominant, than the purple allele (factor)
What was Mendel's third conclusion?
The dominant allele (factor) was being passed down less than the recessive allele (factor).
The dominant allele (factor) of purple flowers was being passed down more than the recessive allele (factor) of white flowers.
The recessive allele (factor) was being passed down more than the dominant allele (factors).
Just because purple is the dominant allele (factor), doesn't mean it is being passed down more, it was just being expressed more.
Mendel's Law of Segregation means?
Every person has two alleles for each trait, they segregate from each other and the dominant is passed more often.
Every person has two alleles for each trait, Where two traits are being passed, they do not effect each other.
Every person has two alleles for each trait, they segregate from each other and are passed down at random.
Every person has two alleles for each trait, they segregate from each other and the recessive is passed more often.
What is Mendel's Law of Independent Assortment?
If the recessive allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.
The passing of allele of one trait does not affect the passing of allele of another trait.
If the dominant allele is passed for one trait, then it is more likely that the dominant allele will be passed for the other trait.
If the dominant allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.
When an organism has two of the same alleles, it is called
homozygous
heterozygous
recessive
dominant
When an organism has two different alleles, it is called
homozygous
heterozygous
recessive
dominant
