On the right, choose which Letter (-) best responds to the statement or description on the left. ssume this figure relates to the Sickle ell Trait, and that s* indicates the sickle cell allele # escriptions Letter nswer 25 Which offspring would have Sickle ell nemia? Offspring labelled Which offspring would not have sickle cell anemia, but would be immune to malaria? Which offspring would have a 50% chance of passing the Sickle ell trait to their offspring? Which offspring would be carriers of the Sickle ell trait, but not express it? Which offspring would have a homozygous recessive genotype? Which offspring would always pass the sickle cell trait to their offspring? Which offspring would be completely free of the sickle cell allele? Offspring labelled Offspring labelled Offspring labelled Offspring labelled and # escriptions Letter nswer 32 This substance is a complex of N and protein hromosome 33 This is the monomer type that makes up both N and RN hromatin 34 oth N and RN are considered to be this type of molecule Nucleotide Nucleic cids arbohydrate Page 3 of 7

4 # escriptions Letter nswer Genetic traits that are expressed independently, each having its own specific characteristic are referred to as this omplete ominance Genetic traits that follow traditional dominance and recessive rules are referred to as this Incomplete ominance Genetic traits that are intermediates, or blends of two different alleles are referred to as this odominance ll of the above omplete and Incomplete ominance # escriptions Letter nswer This is a type of tumor that does not spread or migrate to other regions of the body Proto-oncogene Tumor cells with this characteristic or trait are said to be cancerous or a form of cancer Oncogene This is any collection of cells that have lost control of the cell cycle and are continually reproducing Tumor This was a normal gene that controlled the cell cycle in some way, but has been mutated and now has lost cycle control enign This is when tumor cells do not stay in one place and instead will migrate to other regions of the body Metastasis atching: Select the best match (on the right) for each selection on the left. # escriptions Letter nswer 43 ny genotype on the right that is homozygous recessive MM 44 ny genotype on the right that is heterozygous Mm mm MM and mm Mm and MM Page 4 of 7

Select the offspring (,,) that best represents the description on the left # escriptions Letter nswer 45 Which genotype(s) above are homozygous recessive? Offspring labelled 46 Which genotype(s) would result in a dominant phenotype? Offspring labelled 47 Which genotype(s) above are homozygous dominant?
