If two diploid cells (2n) joined together in sexual reproduction, their fusion would produce a tetraploid zygote (4n). how do cells that fuse together in sexual reproduction ensure the production of a diploid zygote instead of a tetraploid zygote?

a. the chromosomes fuse, which produces cells with half the number of chromosomes.
b. they first undergo meiosis, so these cells have only half the number of chromosomes.
c. the zygote splits in half, which produces two cells, each with half the number of chromosomes.
d. after fertilization, the cell undergoes meiosis, which reduces the number of chromosomes by half.

your answer would be c

explanation:

because if the train is going 70 mph and the purple avacodos are falling from the sky the that means the cats must be a liquid

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
