DIPLOID and HAPLOID WORKSHEET



Name: ________________________________________________ Date: _____________________ Block: __________DIPLOID and HAPLOID WORKSHEETDIPLOID body cells always have an even number of chromosomes because the chromosomes are found in pairs (2n).HAPLOID body cells only contain half the number of chromosomes (n).Complete the following table of chromosome number in various species.Species Name# of chromosomes in diploid cells2n# of chromosomes in haploid cellsnHuman2n = 46n = 23House Flyn = 6monkeyn = 21Bat 2n = 44King Crab2n = 208Goat n = 30Rice2n = 24Armadillon = 32Chicken n = 39Leopard frog2n = 26What is the meaning of diploid?_____________________________________________________________________What cells in living organisms are diploid?_____________________________________________________________What is the meaning of haploid? ____________________________________________________________________What cells in living organisms are haploid?____________________________________________________________What does the symbol 2n represent? ________________________________________________________________What does the symbol n represent? _________________________________________________________________The 2n number for dogs in 78. How many chromosomes would you find in a dog’s blood cell? __________________How many chromosomes would you find in a dog’s sperm cell? ___________________________________________10. If the sperm cell of a fruit fly has 4 chromosomes, then the number of chromosomes in each body cell is:2b) 4c) 6d) 8e) 1611. Of the following cells, the only one to have the haploid number of chromosomes is:a) skinb)musclec) nerved) bloode) ovum12.
