In this dihybrid cross, what is the probability of having a white cat of long tail?

When in a heterozygote plant neither allele is phenotypically prevailing to the other is termed

Term for an organism that has two genetic factors (alleles) identical for a particular trait

In this dihybrid cross, what is the probability of having a brown cat of long tail?

Fossil comparisons of the bones in a horse’s foot reveal that evolutionary change is:

When a species in a new territory evolves into several closely related, yet different species  

Not all species evolve

Of the following traits, which trait is exclusive to living organisms?

The phenotype of an organism

Alteration of the frequency of alleles in the next generation in a small population results in:

In a population of 4000 organisms, how many alleles for the gene “K”are in the population?

All of the following assumptions are required by Hardy and Weinberg principle, EXCEPT

Natural selection

If the freq. of the “L” allele is 0.32 (p), what is the freq. of the recessive “l” allele (q)?

Number of possible different phenotypes that could be obtained in an organism with 200 genes

For two organisms to be of the same species, they must be:

Pattern of long periods of relatively little change followed by short periods of intense change

Some traits in organisms show discontinuous variation (like Mendel's plants). This means:

All of the following provide indirect evidence for the theory of evolution and nat. sel. EXCEPT

All of the following pairs of structures are homologous, EXCEPT:

Disruptive selection favors

What is another name for the sudden appearance of anew allele?

Inheritable mutations are passed on to subsequent generations via
