Genetics Mind Map - Divna Kanazirska 10/5
Chicken
Internal fertilization
gametogenesis
Multicellular
meiosis
Stages of meiosis(each occurs 2 times):
Interphase I
All the DNA is replicated
Prophase
Crossing over occurs
Metaphase I
Chromosomes line up in the middle
Anaphase I
Homologous chromosomes moce to the opposite poles of the cell
Telophase
Cell division begins
Cytokinesis

Sexual Reproduction - a type of reproduction that involves a complex life cycle in which a gamete combines with another to produce an organism composed of cells with two sets of chromosomes
eukaryotic
Coral
External fertilization
The fusion of gametes to form a zygote, which occurs outside the female body
gametogenesis
mitosis
a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei
multicellular
eukaryotic
Humans
Internal fertilization
The fusion of gametes to from a zygote, which occurs inside the female body
meiosis
Multicellular
cell differentiation
Cells differentiate to specialize for different functions
contain body cells
eukaryotic cells
Reproduction system and fertilization:
male
Testis
Vas deferens
a tiny muscular tube in the male reproductive system that carries sperm from the epididymis to the ejaculatory duct
Urethra
Penis
Prostate gland
secretes fluid that nourishes and protects sperm
Diploid cells
female
ovary
Each month a matured egg is released from the ovary and if fertilized, a zygote is formed. If not fertilized, it gets released.
Fallopian tubes
Where the egg is formed
Uterus
Uterine lining
After the egg is formed, it travels to the uterus and implants into the uterine lining, where the fetus will start growing.
Cervix
Vagina

Meiosis
Fertilization
Gametes
gametogenesis
a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
multicellular
A tissue, organ or organism that is made up of many cells
Sexual reproduction
*Or asexual
Ex: potatoes
runners:
strawberry plants create runners
bacteria
single-celled
they reproduce asexually
a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes
similar to mitosis
fertilization
contains only one cell
prokaryotic
Sexual reproduction
Sexual reproduction
eukaryotic
Gametes
ovum/egg
