How many blastomeres and with how many chromosomes are formed from a cow’s zygote after five stages of cleavage? The cow karyotype is 60 chromosomes. Why?
The number of blastomeres will be 25 or 32. Since divisions are mitotic, and zygotes are always diploid, each blastomere will have a diploid set of chromosomes characteristic of a cow, equal to 60.
