Genetics Test Guidelines Sheet

This test covers materials from 2 packets: “Genetics” and “Aspects of Biotechnology” (both of these
packets are white)

Genetics Material:
o Know Mendel’s Law of Segregation and Law of Independent Assortment
o Know terms associated with genetics (allele, dominant vs. recessive, homozygous vs. heterozygote,
phenotype vs. genotype)
o Be able to determine parental crosses, to set up a Punnett Square, and to predict the genotypes and
phenotypes of offspring
o Be able to explain a “test cross” (Remember: A test cross is used to determine the genotype of an
individual that shows dominant phenotype)
 Cross the organism in question with homozygous recessive.
 If all offspring are the dominant phenotype, then the organism in question is homozygous
dominant.
 If the recessive phenotype appears in the offspring, then the organism in question is
heterozygous.
o Know the difference between complete dominance vs. incomplete dominance vs. codominance
 Be able to solve genetic problems and to identify the pattern of inheritance
o Blood Types
 Know blood types (phenotypes) are A, B, AB, & O
 Know the possible genotypes associated with these blood types
 Know what type of blood a person can receive in a blood transfusion based on their blood type
o Sex-linked Traits (X-linked traits)
 Know that human females are XX and males are XY
 Be able to solve genetic problems for sex-linked traits and to predict genotypes and phenotypes
of children
 Know what a “carrier female” means
 Be able to explain why males are more likely than females to suffer from recessive diseases
carried on the X chromosome

Biotechnology Material:
o Know the definitions of restriction enzymes, recognition sites, sticky ends, and DNA ligase.
o Refer to the questions in the biotechnology packet for what you need to know about Gel
Electrophoresis, Polymerase Chain Reaction, Gene Cloning, & Genetically Modified Organisms
o Know the basics of Somatic Cell Nuclear Transfer (Virtual Mouse Cloning) & DNA Fingerprinting
o Know the basics of Epigenetics
