What structure produces sperm cells?
Testes
What structure produces egg cells?
Ovary
What is an advantage for internal development for the human embryo?
Protection
Two liters of kittens are genetically different from each other and their parents. What are their genetic differences due to?
Meiosis - sexual reproduction
Are the daughter cells at the end of mitosis the same of different from the parent cell? Are the daughter cells at the end of meiosis the same of different from the parent cell?
The same and different respectively
What is the primary function of the male reproductive system?
Produce and transport gametes
Where does the embryo develop in the female?
Uterus
What is an example of an environmental factor that could influence the development of a fetus?
-Alcohol, smoke, toxins, nutrition, drugs
What is cell differentiation?
Process of cells becoming specialized and unique
What types of cells go through the process of mitosis? meiosis?
Body Cells and gametes respectively
Bonus: Are they haploid or diploid cells?
Where is the hormone testosterone synthesized?
Testes
Where is the site of fertilization?
Fallopian Tube
Why is the first two months a pregnancy crucial for the embryo?
Crucial organs form during this time
How are cells different if they all have the same DNA?
Different genes activated
What occurs before a cell can divide in both mitosis and meiosis?
Interphase - cell has to replicate DNA
What may happen if the vas deferens is blocked in the male?
No delivery of gametes
A female dog has 13 chromosomes in her egg cell. How many chromosomes would be in her skin cell?
26
Bonus - How many chromosomes would be in her male counterparts sperm cells?
Put the following processes in order.
a. mitosis
b. meiosis
c. fertilization
d. differentiation
b-c-a-d
Why would a sexually reproducing organism be more likely to survive a disease than a asexually reproducing organism?
-Genetic diversity means entire population does not get wiped out
Bonus: Why would the asexually reproducing offspring have a better chance?
Draw a diagram of the process of fertilization forming a zygote.
CELLS ONLY DRAWING
sperm + egg yields zygote
A mutation occurred in a male, in order for the mutation to be passed on to its offspring, what cells would have to be affected?
Gametes
What hormone(s) in the female regulate the reproductive cycle?
Estrogen and progesterone
Describe the role of the placenta in a pregnancy.
Transfer of nutrients, gases, and wastes from mom to fetus and vice versa.
Bonus - how does it work?
