Presentation transcript:

Human karyotype How many pairs of chromosomes are there? How many chromosomes does a human cheek cell contain? How many chromosomes does a human ovum contain? How are the chromosomes arranged? What is the sex of this person? Reason for your answer:

Human karyotype are arranged pairs. Chromosomes in homologous arranged according are arranged pairs. There are chromosomes are karyotype to Chromosomes size. of chromosomes. in homologous The

Human karyotype are arranged pairs. Chromosomes in homologous arranged according are arranged pairs. There are chromosomes are karyotype to Chromosomes size. of chromosomes. in homologous The

easier more difficult are arranged pairs. Chromosomes in homologous according The pairs. arranged Chromosomes are size. to in homologous

in homologous pairs. 23 pairs male How many pairs of chromosomes are there? How many chromosomes does a human cheek cell contain? How many chromosomes does a human ovum contain? How are the chromosomes arranged? What is the sex of this person? Reason for your answer: 23 pairs A cheek cell is a normal body cell, therefore it contains 23 pairs of chromosome, i.e. 46 chromosomes An ovum is a gamete, therefore it contains only 23 chromosomes in homologous pairs. male In humans a sex chromosome arrangement of XY is male (XX is female)
