Exam 7: Genetics

In pea plants,the smooth seed trait is dominant to the wrinkled seed trait and the green pod trait is dominate to the yellow pod trait.If a pea plant that is homozygous dominant for both traits is crossed with a pea plant that is homozygous recessive for both traits what will be the expected phenotypes of the offspring of this cross?

Somatic mutations are always passed along to offspring.

Mendel's principle of segregation relates directly to an event that occurs in ________ of meiosis.

A cross between two F1 pink dahlia yields plants with 9 varieties of flower color.This is an example of which of the following?

Transcription leads to the production of ________ whereas translation leads to the formation of ________.

A point mutation is a change in which of the following?

Which of the following was unknown during Mendel's time?

Which of the following is not correct?

The first flowering plant genome that was sequenced was this species.

Alternative forms of the same gene are called which of the following?

Linked genes

Approximately 99.9% of the human genome consists of genes comprising DNA that codes for proteins.

In addition to mutations,other inherited changes can cause chemical changes to chromatin.Epigenetics is the study of the inheritance of these changes,often involving a methyl group attachment to either a nucleotide or a histone protein.

A cross between pure-breeding red carnations and pure-breeding white carnations yields all pink carnations.This is an example of which of the following?

A pea plant received a dominant allele for flower color from one of its parents and a recessive allele for flower color from its other parent.The genotype of this pea plant is called which of the following?

The actual coding part of a gene is called which of the following?

Which of the following could be an RNA codon?

In a cross between a pure breeding tall (dominant)plant and a pure breeding dwarf (recessive)plant,the expected phenotypes of the offspring will be which of the following?

Which of the following crosses will produce offspring that show the recessive phenotype?

In pea plants,the smooth seed trait is dominant to the wrinkled seed trait and the green pod trait is dominate to the yellow pod trait.If a pea plant that is homozygous dominant for both traits is crossed with a pea plant that is homozygous recessive for both traits what will be the expected genotypes of the offspring of this cross?
