Help Please :) How many chromosomes should a cell used in sexual reproduction have?

- half as many as the species normally has in its diploid cells, so that the other chromosomes can come from the other parent

- exactly one chromosome, regardless of species, so that the offspring can develop its own genetic code and increase diversity

- exactly as many as the species normally has in its diploid cells, so that the offspring’s genetic code is the same as the parents'

- twice as many as the species normally has in its diploid cells, so the offspring will have all the traits from both parents

the third one bc everyone one has the same amount of chromosomes yea someone might have half of each parent but they will still have the same amount as the parents so if both parents have 23 pairs each then the child will have 23 pairs of chromosomes.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

the median of the data is 4.5.
