Reproduction Flashcards
Gametogenesis
Formation of gametes
Sperm production process? How long? Where
Spermatogenesis and 64 days. In testes or epidydimis
Oogenesis = ?
Ova production in females within the ovaries
Ovulation under control of what hormones
Follicle stimulating hormone. hormonal regulation = ovulation of mature follicle which releases ovum.
What is the ongoing cycle cells undergo
growing, dividing and dying AKA apoptosis.
Bacteria undergo
Binary fission = DNA replicates and then cell divide into two. Mitochondria and chloroplast. 20-30 minutes
Yeast undergo
Budding = small amount of cell pinches off and then divides into two cells. A clone is produced
Paired arrangement of chromosomes are KA. Obtained from what
homologous chromosomes - maternal and paternal derivatives
Homologous chromosomes where
Somatic autosomal cells
True or False: there is a correlation between the number of chromosomes in a cell and the degree of complexity of the cell division.
false. There is no correlation
Asexual reproduction can produce
A clone ie genetically identical organism to their parent organism/cells.
What does asexual reproduction not involve?
Meiosis, ploidy reduction or fertilization
How many chromosomes in humans?
23 pairs -44 autosomal and then two sex chromosomes.
