45.C a mixture of maternal and paternal chromosomes .
The meiosis I starts with the diploid parental cells and forms the 4 haploid cells after cell division. They contain paternal and maternal chromosomes and after recombination (exchange of gene) ,the daughter cells get the combination of the maternal and maternal chromosomes. The sister chromatid is generated during S phase ,each chromosomes duplicates to form sister chromatids. In meiosis II, the formation of 4 daughter cells occurs i.e.the daughter cell receives one -fourth the amount of DNA that is in parent nucleus.During mitosis,the daughter cell receives the same number of chromosomes as that of diploid cell.
46.S phase .
In eukaryotic cell cycle, in prophase - chromatin condenses into chromosome,G1 phase -cell growth, G2 phase -growth and cell prepares for mitosis ,M phase - cell divides (mitosis).

Simulate mitosis by drawing and include the following: Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 homologous pairs of chromosomes (the cell has more chromosome pairs, but we are just looking at 2 of them) It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . There should be one gene on each chromosome. Go through...

Can someone please check my answer? Understanding chromosome number and behavior during cell division is an important concept in genetics. Fill out the chart below for each phase of mitosis in terms of N (where N = haploid number). For example, humans have a haploid number of 23. There are 46 chromosomes (2N) present in prophase of mitosis. Each chromosome is present in its replicated form (i.e. as sister chromatids) so there will be 2 chromatids per chromosome and the...

The choices are mitosis, meiosis, both or neither. - two identical daughter cells are formed - sister chromatids are separated - homologous chromosomes are separated - nuclear envelope dissolves during prophase - cytokinesis occurs simultaneously with teleophase - DNA replication occurs during early prophase - Final product is 4 different daughter cells - final product is 4 diploid daughter cells - Final product is 2 diploid daughter cells - Final product is two haploid daughter...

Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...
