Purple flowers (P) are dominant to white flowers (p) in pea plants. If two pea plants were crossed and both were heterozygous for the trait of flower color…   What would the genotypic ratio of the offspring be?

In horses, a black mane (B) is dominant to a blond mane (b).  A horse with a black mane is mated to one with a blond mane.  They have several offspring, some with black manes and some with blond-manes. What is the genotype of the blond-maned parent?

What event accounts for the recombination of linked genes?

Given the DNA sequence: GGT – AAA – AGC – ACT What mRNA sequence would be transcribed? [Write your answer without spaces or dashes]

Individuals having two different alleles for a given gene are…

During translation, this form of RNA acts as the “molecular interpreter” reading the mRNA and placing amino acids in order.

What kind bonds link together nucleotide base pairs (ATCG) on opposite strands of the double helix?

A genetic disease, such as achondroplasia, which only requires one disease allele to be expressed in an individual is said to be a                       disorder.

Human height is controlled by the combined effects of many different genes.  Being tall, is a               trait.

If an organism has the recessive phenotype, they must have this genotype.
