(2) Recombinant chromatids are the result of crossing over 
(3) Independent assortment is a random combination of chromosomes present in meiosis.
(4) Apoptosis is cell death that occurs in multicellular organisms.
(5) Independent assortment is random and purely based on chance while in crossing over, exchange only happens in homologous chromosomes.
(6) Mitosis is a type of cell division the results in two identical daughter cells. Meiosis goes through two rounds of division and is used in gametes.
(7)  Skin cell-6, gamete-3
(8) Two reasons cells may undergo apoptosis is because withdrawal of positive signals or just programmed cell death needed for mitosis.]]> 2021-04-10 00:57:06 UTC https://padlet.com/MsLeCour/pvgb66xd57krgqry/wish/1401838598 Tiana toquend004 https://padlet.com/MsLeCour/pvgb66xd57krgqry/wish/1421322639 (1) The process where genes are being exchanged resulting in a mixture of parental characteristics in the offspring

(2) Recombinant chromatids: It is increases genetic variation among the products of meiosis be reshuffling genetic information between homologous chromosome pairs

(3) Independent assortment: A matter of chance which member of a homologous pair goes to which daughter cell at anaphase

(4) Apoptosis: Is a genetically programmed series of events that result in cell death

(5) Crossing over and independent assortment during meiosis result in daughter nuclei that differ genetically is that crossing over exchanges only happening in homologous chromosomes and independent assortment is random and based on chance/lucky

(6) The differences between meiosis and mitosis is meiosis have two rounds/sets of division and use in gametes. Mitosis is single set a cell division to having the results of two identical daughter cells

(7) There is 3 chromosome cells in a gamete There is 6 chromosome cells in a skin cell

(8) The two reasons for apoptosis is the cells will undergo due to withdrawal of positive signals or programmed cell death needed for mitosis

2) Recombined chromatids increases genetic variation among the products of meiosis by reshuffling genetic information between homologous chromosome pairs.
3) Independent assortment is the matter of chance which member of a homologous pair goes to which daughter cell at anaphase.
4) Apostis is genetically programmed series of events that result in cell death.
5) Crossing over and independent assortment during meiosis result in daughter nuclei that differ genetically because crossing over exchanges the DNA in the homologous chromosomes and independent assortment is based is random and based on chance. 
6) The differences between mitosis and meiosis is that mitosis has one round of cell division and it focuses on creating body cells and results in 2 diploid cells with 46 chromosomes while meiosis has two rounds of cell division and it creates sex cells.It results in 4 haploid cells with 23 chromosomes each.
7) The sex cells for the animal has 3 and the skin cells have 6.
8) Two reasons for apoptosis is

the cells will undergo due to withdrawal of positive signals or programmed cell death needed for mitosis

2) Recombinant chromatids: it increases genetic variation among the products of meiosis by reshuffling genetic information between homologous chromosome pairs. 
3) Independent assortment: It is a matter of chance which member of a homologous pair goes to which daughter cell at anaphase I. 
4) Apoptosis: is a genetically programmed series of events that result in cell death. 
5) Crossing over and independent assortment during meiosis result in daughter nuclei that differ genetically because crossing over exchanges the DNA in the homologous chromosomes and independent assortment is based is random and based on chance. 
6) Mitosis is one round of cell division and ends up having the two diploid somatic cells at the end and they identical to the parents. Meiosis is two rounds of cell division and is used in gametes. It ends up having 4 haploid cells at the end of its cell division process. 
7) Skin cell has 6 and the gamete has 3.
8) Two reasons why cells undergo apoptosis are because the cell is no longer needed by the organism and the longer a cell lives the more prone it is to genetic damage and that can lead to cancer.
