Summary Introduction
To review:
The term diploid and mention the diploid cells of the human body.
Introduction:
Inheritance of the character (trait) through reproduction was first demonstrated by Gregor Mendel in the 19th century. He crossed two different traits of pea plant to produce an offspring of mixed traits, which led to the discovery of heredity of genes.

- 9) A diploid cell is preparing to undergo meiosis. Before the 'S' phase, the cell has 6 picograms (pg) of DNA in it. Answer the following: a) After the 'S' phase of the cell cycle what ploidy is the cell? How many picograms of DNA does it contain? b) After meiosis I, how many daughter cells are there total? What is the ploidy of each cell? How many picograms of DNA does each cell contain?arrow_forwardA diploid organism produces four gametes from one parent cell through the process of meiosis. Two gametes are found to have 7 chromosomes and two gametes are found to have 5 chromosomes. A) Is this the expected number of chromosomes that would be found in each gamete following a normal cycle of meiosis? If yes, explain why. If no, explain why not and describe how the gamete situation described above occurred. B) Determine the number of homologous chromosome pairs that the original parent cell contained, before meiosis began. Explain how you determined this value.arrow_forwardA boy with Down syndrome (trisomy 21) has 46 chromosomes.
