Example of a human karyotype: 23 pairs of homologous chromosomes (one pair is the homologous 'sex' chromosomes - in this case X and Y = a boy) III. Meiosis reduces chromosome number from diploid (2n) to haploid (n) 1 diploid cell (2n) cell becomes 4 haploid (n) germ cells (eggs or sperm). 1 In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.  The number of chromosomes is reduced from 46 to 23 during the process of meiosis. Fertilization of the egg by the sperm restores the diploid number of 46 chromosomes. 1 We are experiencing some problems, please try again. 2  You can only upload files of type PNG, JPG, or JPEG. 3  You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM.

C) If the two alleles at a locus differ, then one (the dominant allele) determines the organism’s. appearance, and the other (the recessive allele) has no noticeable effect on appearance. D) The “law of segregation” --- Mendel did not know about genes or chromosomes per se. 1 Germ cells have only half the number of chromosomes as a diploid cell ­ one of each pair - and are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.  The number of chromosomes is reduced from 46 to 23 during the process of meiosis. 1 You can only upload photos smaller than 5 MB. 2  You can only upload videos smaller than 600MB. 3  You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm).

All cells in a higher eukaryote (like us) are diploid ­ EXCEPT...for the germ cells ­ eggs and sperm. 1 You can only upload files of type PNG, JPG, or JPEG. 2  You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM. 3  You can only upload photos smaller than 5 MB.
