Thus, half of the gametes carry one allele of a , and the other half carry the other allele. Then, of an egg by a sperm creates a new individual that now possesses two factors for each trait, just like the parent.

Half of the gametes carry one allele of a chromosome, and the other half carry the other allele.Then, fertilization of an egg by a sperm creates a new individual that now possesses two factors for each trait, just like the parents.

Explanation:

The female gamete is called ova which bear 'XX' chromosome and the male gamete is called as sperm that contain 'XY' chromosome.

Fertilization means the fusion of male gamete with the female gamete, which occurs at the ampulla of fallopian tube.This  causes formation of zygote which bear haploid cells.

During fertilization, the sperm is capacitated and is attracted towards progesterone which contain CatSper receptor and helps in increase intracellular calcium level.

The tail of sperm disintegrates after the entry of sperm towards the cytoplasm and cortical reaction takes place.Zygote formation takes place after fusion of perm with the ova.

The sperm undergo capacitation that increase the motility and membrane destabilization occurs.

i think its both a and b

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this
