RAFT: Genetics
Overview: These tiered RAFT assignments give students an opportunity to apply their
knowledge of the key terms, concepts, and processes typically highlighted in a middle
school-level genetics unit. They are listed in order of difficulty, with the first being the
most difficult. Students may complete them individually or with partners.
Standards:
 Investigate and understand that organisms reproduce and transmit genetic information
to new generations
 Utilize appropriate information systems to build an understanding of heredity and
genetics
Objectives:
The students will KNOW
 Vocabulary: gene, DNA, RNA, recessive trait, dominant trait, bacteria, virus,
mutation, zygote.
The students will UNDERSTAND THAT
 Genes are units of information.
 Parents transmit genes to their offspring.
 Some medical conditions and diseases are genetic in origin.
 The processes involved in sorting and recombining parents' genetic material
create potential variation among offspring.
 Chromosomes contain genetic information which can be categorized as recessive or
dominant; the differences between the two determine the expression of genetic traits.
The students will BE ABLE TO
 Explain the role of each parent in the transfer of genetic traits.
 Evaluate the role and function of DNA in a human cell, bacteria, or virus.
 Explain the significance of reproduction.
 Summarize the genetic transmittance of disease.
