Genetic Screening Phenotype and Genotype Lab Report

Help me study for my Biology class. I’m stuck and don’t understand.


Fill out the document attached and do the lab. make sure to upload photo in docmuemnt. , you will perform genetic screening of chromosomes through karyotyping. You will karyotype two sets of chromosomes to determine if the genotype of the chromosomes results in a genetic disease with a specific phenotype.




Part 1: Karyotyping

  1. Review the idiograms (photograph or drawing of chromosomes) shown in Figure 5.


The image shows the idiograms depicts the human chromosomes 1 through 22 decreasing in size and X and Y on bottom right with X being bigger then Y. Image copyright Alila Soa Mai, 2013. Used under license from

  1. Print a copy of the “Possible Chromosomal Disorder #1” (also shown in Figure 6). Use scissors to cut out each of the chromosomes.
