Genetics

Gregor Mendel was:

• an English scientist who carried out research with Charles Darwin
• a little known Central European monk
• an early 20th century Dutch biologist who carried out genetics research

Which of the following statements is true about Mendel?

• His discoveries concerning genetic inheritance were generally accepted by the scientific community when he published them during the mid 19th century.
• He believed that genetic traits of parents will usually blend in their children.
• His ideas about genetics apply equally to plants and animals.

Mendel believed that the characteristics of pea plants are determined by the:

• inheritance of units or factors from both parents
• inheritance of units or factors from one parent
• relative health of the parent plants at the time of pollination

An allele is:

• another word for a gene
• a homozygous genotype
• a heterozygous genotype
• one of several possible forms of a gene

Phenotype refers to the ______________________ of an individual.

• genetic makeup
• actual physical appearance
• recessive alleles

When the genotype consists of a dominant and a recessive allele, the phenotype will be like _________________ allele.

• the dominant
• the recessive
• neither

The idea that different pairs of alleles are passed to offspring independently is Mendel's principle of:

• unit inheritance
• segregation
• independent assortment

The idea that for any particular trait, the pair of alleles of each parent separate and only one allele from each parent passes to an offspring is Mendel's principle of:

• independent assortment
• hybridization
• segregation

What is the study of heredity?

• Hereditology
• DNA
• Genetics
