Sperm penetrates the outer membrane of the ovum and makes the journey through the ovum's cytoplasm to penetrate the nucleus. The sperm's chromosomes become a part of the nuclear material in the fertilized ovum, now called a zygote.]]> 2016-10-05 21:15:39 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128646606 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128646692 Contains 46 chromosomes. 23 from Mom and 23 from Dad.]]> 2016-10-05 21:16:21 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128646692 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128673948 2016-10-06 02:05:36 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128673948 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128674232 2016-10-06 02:08:28 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128674232 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128674301 The chromosomes begin to divide within hours of conception, replicating themselves. Chromosomes and nuclei pull apart producing new cells. This process is called mitosis and continues producing millions of cells. ]]> 2016-10-06 02:09:21 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128674301 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128675307 2016-10-06 02:19:42 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128675307 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128675365 Over 2 weeks the growing organism migrates down the Fallopian tube into the uterus and through implantation attaches itself to the uterine lining.

Genes are "coded" sections of DNA. Genes, like chromosomes, come in matched pairs. Gene expression during transcription and translation is influenced by the environment of the cell. Different varieties of genes are alleles. The embryo gets alleles, one from each parent to determine a genotype. Such as one parent with attached ear lobes and one parent with unattached ear lobes.]]> 2016-10-06 03:02:39 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128679032 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128680788 2016-10-06 03:24:14 UTC https://padlet.com/sansom_a/ehzexty7qwef/wish/128680788 sansom_a https://padlet.com/sansom_a/ehzexty7qwef/wish/128680932 The embryonic period occurs from week 3 to week 8 of the gestational period.
