1. Identify the chromosome number in the leaf cell: - The question states that a leaf cell of a flowering plant has 22 chromosomes. This indicates that the leaf cell is diploid (2n), where 'n' represents the number of chromosomes in a gamete. 2. Determine the haploid number (n): -...
If a somatic cell had 8 chromosomes and went through mitosis, how many chromosomes would be in the daughter cells? What are the number of chromosomes present in Meiosis I: Prophase I Metaphase I Anaphase I Telophase I In mitosis, if a parent cell has 46 chromosomes, each daughter cell...
Meiosis is a special form of cell division that maintains the correct number of chromosomes in gamete cells, proceeding continuously through several phases. Meiosis I is the phase in which two haploid cells are produced from a single diploid cell. What happens during the pachynema stage of ...
Hi, How does the number of chromosomes in a parent cell compare with the number of chromosomes in a daughter cell? Why is this important? In human cell mitosis, each daughter cell will have the same number of chromosomes as the pare...
The Gossypium genus contains 5 tetraploid (AD1 to AD5, 2n = 4×) and over 45 diploid (2n = 2×) species (where n is the number of chromosomes in the gamete of an individual), which are believed to have originated from a common ancestor approximately 5–10 million years ago6. Eight...

The lack of sex chromosomes in haploid Plasmodium hampers our understanding of the commitment to sexual differentiation and the timing of sex determination [15]. Sex determination could occur at the same moment when commitment to sexual differentiation is determined [13], or alternatively via a two...
Regenerating worm tips and gamete-bearing segments were used for the analysis. A diploid chromosome number of 34 was found in well-spread metaphase plates of somatic cells. A pair of sex chromosomes (XY) with the Y considerably larger than the X was found in males. The size and shape of ...
the studies identified 5 autosome pairs in both sequenced mosses, but two autosomes were found only once. Their missing homeologues appear to have become parts of the sex chromosomes, explaining the observed autosome number, and also explaining the high sex chromosome gene number mentioned above (...
Accordingly, the tree was considered to have originated from a union of an unreduced gamete (n = 90) and a reduced gamete (n = 45) of the same species; 'Tone Wase', a spontaneous bud sport of 'Hiratanenashi', also has 135 chromosomes in its somatic cells. 2. Differences in the ...
