T2 - The Law of Segregation explains why, if you start with 46 choromosomes, Meiosis produces cells with how many chromosomes?

• 44
• 22
• 46
• 23

T2 - Which law states that organisms inherit 2 copies of each gene and donate one to their offspring

• law of independent assortment
• law of segregation
• law of genetic linkage
• law of inheritance

T2 - Recessive alleles may not be expressed because they are

• masked by the dominant allele
• the least common allele in the population
• the most common allele in the population
• less likely to having crossing over

T2 - An allele whose trait always shows up in the organism when the allele is present.

• recessive allele
• dominant allele
• hidden allele
• present allele

T2 - Based on the picture of Mendel's experiment, which of Mendel's Laws could you propose?

• Law 1, The Law of Dominance
• Law 2, The Law of Segregation
• Law 3, The Law of Independent Assortment
• Both Law 1 and Law 2

T2 - Which observation of dihybrid crosses led to Mendel's law of independent assortment

• Particular individual traits persisted for many generations
• Many combinations of traits were always inherited together
• Some combinations of traits were not passed onto offspring
• The presence of one trait didn't affect the presence of another

T3 - A distinguishing characteristic can be inherited as a(n)

• gene
• allele
• trait
• characteristic
