4 Explain the reason for sexual reprodution

 

1) List 10 parts of male reproductive system

1. pubic bone
2. ductus deferens
3. penis
4. spongy urethra
5. bladder
6. seminal vesicle
7. prostate gland
8. epididymis
9. testis
10. scrotum

2) List 8 parts of female reproductive system

1. uterine tube
2. uterus
3. ovary
4. cervix
5. vagina
6. clitoris
7. labium minus
8. labium majus

3) List 4 parts of a spermatozoan

Answer:

1. acrosome
2. nucleus
3. midpiece
4. flagellum

4) Explain the reason for sexual reproduction

answer: The reason for sexual reproduction is that the offspring which arise from sexual reproduction will have genetic diversity as gametes that fuses are from different individuals which leads to diverse phenotype and which enhance the survival of a population in a changing environment.

5) Independent assortment on metaphase plate of meiosis results in about 8 million different types of sperm

Answer: true

Explanation:

human have 23 pairs of chromosomes. Each pair in the phase of metaphase I has 2 possible combinations. combine that 23 times and you get

2²³ = 8 million

So as you can see, independent assortment can give raise to 8 million different sperm or eggs.

6) The above process and random fertilization along with crossing over is the reason that the potential of the human race is well over 64 trillion types of zygotes 

Answer: true

Explanation:

2²³ x 2²³ = 64 trillion

All of these 3 mechanisms (crossing-over, independent assortment and random fertilization) working together create the reason that the potential of the human race is over 64 trillion types of zygotes.

• crossing-over = exchange of genetic material between homologous chromosomes, resulting to new combinations of genes on each chromosome
• independent assortment = homologous chromosomes randomly distributed to daughter cells, and different chromosomes segregate independently of each other
• random fertilization = two gametes together produce an offspring and the possible gametes are a mater of chance
