The physical appearance of an organisms is also referred to as:
genotype
phenotype
chromosome
incomplete dominance
The genotype is:
the genetic makeup of an organism.
the physical appearance of an organism.
the deletion of a chromosome.
the passing of traits from parent to offspring.
Which of the following is true regarding inheriting traits:
Dominant traits are less likely to be seen.
You must have only one recessive gene in order to express the trait.
The recessive trait always is seen over the dominant trait.
Dominant traits are more likely to be expressed because you only need one gene.
