How does the production of sperm differ from the production of eggs? a. Sperm production involves meiosis, whereas egg production involves only mitosis. b. Meiosis during sperm production produces four sperm cells, whereas meiosis during egg production produces only one functional egg cell. c. Sperm are haploid, whereas eggs are diploid. d. Sperm production begins during fetal development, whereas the meiotic process that begins egg production doesn’t begin until puberty
How do you expect Kartagener syndrome leads to infertility?
A. The lack of a plasma membrane means that pathogens and foreign substances can permeate the sperm and damage the DNA
B. The lack of microtubules mean the sperm do not have tails and cannot swim to fertilize the egg
C. The lack of dynein means that the sperm cannot bend their tails to swim and fertilize the egg
Which cell contributes the necessary nutrition to the growing zygote?
a
a polar body
b
