traits and inheritance

The one thing that Gregor Mendel realized could explain the results of his experiments was that

• the traits were appearing at random
• the male traits were always the dominant ones
• each trait had two sets of instructions, one from each parent
• his important research would open the door to modern genetics

Instructions for an inherited trait are called

• alleles
• albinism
• phenotype
• genes

The different forms of a gene that determine a characteristic are known as

• alleles
• albinism
• phenotype
• genes

What did Mendel discover about recessive traits?

• recessive traits reappear in the second generation, after disappearing in the first generation 
• recessive traits disappear altogether
• recessive traits never appear in the second generation
• recessive traits become dominant

What is a feature that has different forms in a population?

• pedigree
• fertilization
• characteristic
•  trait

What is a trait?

• different forms of meiosis
• different forms of chromitids
• different forms of a pedigree
• different forms of a characteristic

When a plant fertilizes itself, it is called a(n)

• allele plant
• self-pollinating plant
• true-breeding plant
• cross-pollinating plant

When there is incomplete dominance,

• one allele has more influence than the others
• each allele has its own degree of influence
• the alleles have no influence
• there are no alleles present

What is heredity?

• traits passing from offspring to parents
• plants that are cross-pollinated
• traits passing from parents to offspring
• the ratio of dominant to recessive traits
