If two first-generation self-pollinating plants are crossed, Pp x Pp, what is the PROBABILITY that offspring plants will show the recessive trait, pp? | 1/4 |
If you cross two rabbits that have the genotype Bb, how many possible GENOTYPES can be found in the offspring? | three |
In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype. This is an example of which of Mendel’s laws? | dominance |
In a plant, tall (D) is the dominant allele. Short (d) is the recessive allele. Which GENOTYPE would a short offspring have? | dd |
The likelihood that an offspring will have a genetic disorder, such as sickle cell disease, depends on what factors? | the traits passed on by parents |
What are the possible genotypes of the offspring if you cross a white flower (with the genotype pp) with a purple flower (with the genotype PP)? | all Pp |
What is the process by which individuals that are better adapted to their environment survive and reproduce more successfully than others do? | natural selection |
Mitosis produces _______ while meiosis produces ________. | body cells, sex cells |
What is the number of chromosomes in a body cell (somatic) known as? | diploid |
If a scientist is trying to decide if a molecule is RNA or DNA, for what should he test? | thymine |
What type of mutation has occurred if a DNA sequence that initially reads ATTGCCGAT now reads ATTGCCAT after being copied? | deletion |
What type of mutation has occurred if a DNA sequence that initially reads ATTGCCGAT now reads ATTGCCAGAT after being copied? | insertion |
Alleles for different traits are distributed to sex cells & offspring independently of one another. This is an example of which of Mendel’s laws? | independent assortment |
