1. Chromosomes and Characteristics  Chromosomes carry genes and come in pairs  Genes come in different varieties and these are called alleles  We have two alleles for each trait, one from each parent  The combination of alleles is the genotype  The characteristics that are produced are the phenotype (Hint, the following pretty much sums up question 2 on page 23)

3. Chromosomes and Characteristics Learn.Genetics™ On the link below, click on “Heredity and Traits”: You may also want to click on “DNA to Protein” to review DNA replication 1) Based on your readings in the text and the interactive animations on the Learn Genetics website, complete pages 23-24. 2) When done, read “Sexual Reproduction” (page 25) and begin working on pages 27-29. 3) Remember our homework – I’ll be coming around to check that you have up to page 21 done. If you don’t, get it done by Thursday or you will be joining me for Thursday homework club or Thursday lunch to finish it.
