Reproductive: Overview Flashcards
What is the purpose of the reproductive system?
To ensure the survival of the specials of animal
True or False: The reproductive system does not interact with other systems
False - it does interact with other systems
True or False: Purely reproductive structures are essential to the life of an animal
False - Not essential to life
How does the reproductive process begins?
Fertilization
What is fertilization?
Head of spermatozoon must penetrate into cytoplasm of ovum
What is created from meiosis?
Gametes (ova, spermatozoa)
What does the meiosis process ensure?
That the genetic makeup of each new animal is unique
The genetic material in the body’s cells is contained in the ________ in the form of coiled masses of DNA called __________
Nuclei; chromosomes
True or False: Each cell in animal’s body (except for gametes) contains identical chromosomes
True
Total number of chromosomes in the nucleus of each cell is called?
the diploid chromosome number (2n)
True or False: The diploid chromosome number is always an even number
True - chromosomes occur in pairs
One of the pairs of chromosomes that makeup the diploid chromosome number are?
Sex Chromosomes (determine genetic gender of animal)
Genetically female is:
XX chromosomes
Genetically male is:
XY chromosomes
The reduced number of chromosomes in the gametes is called?
Haploid Chromosome Number
What does haploid chromosome number result from?
Meiosis
What is meiosis referred to as?
Reduction Division
What is Mitosis?
(Make It Two) - Each chromosome produces a duplicate copy of itself (half in each cell)
What is meiosis?
(Make Each Individual) - Each cell division is different. Random half of total chromosomes go to each daughter cell
