5 Written Questions

1. a cross in which only one characteristic is tracked
2. members of a pair of homologous chromosomes separate during the formation of gametes and are distributed to different gametes so that every gamete receives only one member of the pair
3. diagram showing the relative locations of each known gene on a particular chromosome
4. one allele is completely dominant over another
5. genes that are located close together on the same chromosomes usually travel together during gamete formation

1. a The existence of more than 2 alleles of the same gene
2. b what an organism looks like as a consequence of its genotype
3. c a cross in which two characteristics are tracked
4. d term used to refer to an organism that has two different alleles for the same trait

1. genetic makeup of an organism
   1. gene map

5 True/False Questions

1. punnett square → what an organism looks like as a consequence of its genotype

   True        False

2. antigens → molecule on the surface of a cell that identifies it as a foreign invader to the immune system

   True        False

3. co-dominance → a condition in which neither of two alleles of a gene is dominant or recessive

   True        False

4. recessive → trait that will only appear in the phenotype if organism inherits two of them; covered up by the dominant gene

   True        False

5. agglutinate → stick together to form clumps

   True        False
