Question
How can homologous chromosomes be identified?

What is the major chromosomal difference between gametes and body cells?

Based on the evidence obtained from your karyotype,what is the sex of yhis individual? How do you know?

list some genetic disorders that can be determined by this process.

What process can produce the disorders listed above

thank you  

Answer
Hi Stephanie
 Only by test crossing

Gametes (sperms and eggs ) have only half the chromosome numbers

 You have not given me the karyotype

 Some disorders that can be found:
   Klinefelters
   Turners
   Supramale
   Megafemale
   Trisomy 21
 All can be produced through chromosomal damage.
 You can look up these disorders to find out the symptoms
