Embryology

Please only take this problem if you can answer it completely. Thank you! Describe the process of Oogenesis and vitellogenesis. Where do different events occur?

pre-test

answer questions correctly. (1)a sexually producing organism has 12 chromosomes in each somatic cell, how many chromosomes would you find in the organism's gametes (sperm/egg)? (2)the # of chromosomes in the human white blood cell is? (3)the exchange of genes between pairs of homologous chromosomes is called? (4)the # of male gametes (sperms) produced after one complete meiotic cell division is? (5)when a pure-breeding red flower snapdragon is crossed with a pure-breeding white flower snapdragon plant it produced plants with pink flowers. this is referred to as? (6)the # of amino acids those participate in protein synthesis are? (7)when the centromere divides and chromosomes begin to ... click for more

Questions on the sexual reproductive system in mammals, the urogenital system, fertilization, and cleavage

1. Trace the pathway of a sperm from the male testes to the uterine tube of a female. 2. Fertilization involves much more than a mere restoration of the diploid chromosome number. What does the process of fertilization entail on the part of both the egg and sperm? What are the effects of fertilization? 3. Why is the term urogenital system more applicable to males than to females? 4. Cleavage is an embryonic event that mainly involves mitotic division. How does cleavage differ from mitosis occuring during life after birth, and what are its important functions?
