Mutations that occur in germ cells (gametes):
Are never inherited by offspring
Only affect the individual in which they occur
Can be inherited by offspring
Are always beneficial
Which cellular structures are involved in cytoplasmic inheritance due to the presence of their own DNA?
Ribosomes and Endoplasmic Reticulum
Lysosomes and Golgi apparatus
Mitochondria and Chloroplasts
Nucleus and Nucleolus
Which of the following genetic principles explains why a plant heterozygous for flower color (e.g., Rr) produces gametes with either R or r alleles?
Mendel's Law of Independent Assortment
Mendel's Law of Segregation
Incomplete Dominance
Co-dominance
In a certain flower species, red (R) is incompletely dominant over white (r). If a red flower is crossed with a white flower, what percentage of the offspring will be pink?
0%
25%
50%
100%
A person with AB blood type demonstrates which genetic principle?
Mendel's Law of Segregation
Mendel's Law of Independent Assortment
Incomplete Dominance
Co-dominance
If two traits are always inherited together, what can you infer about the genes controlling these traits?
They follow Mendel's Law of Independent Assortment.
They are likely linked on the same chromosome.
They exhibit incomplete dominance.
They exhibit co-dominance.
The definitive evidence establishing DNA as the genetic material was derived from the experiments of:
James Watson and Francis Crick
Frederick Griffith
Oswald Avery, Colin MacLeod, and Maclyn McCarty
Alfred Hershey and Martha Chase
Which experiment definitively proved that DNA, and not protein, carries genetic information?
Griffith's transformation experiment
Avery, MacLeod, and McCarty's experiment
Meselson and Stahl's DNA replication experiment
Hershey and Chase's bacteriophage experiment
In Hershey and Chase's experiment, what was the key observation that supported DNA as the genetic material?
Radioactive sulfur () was found inside the bacteria.
Radioactive phosphorus () remained outside the bacteria.
Both radioactive sulfur () and phosphorus () were found inside the bacteria.
Radioactive phosphorus () was found inside the bacteria.
