how many chromosomes are in a strawberry?
148497
The strawberry of commerce is octoploid (2n = 8× = 56; seven chromosome sets and eight chromosomes per set, 56 total), meaning that each cell contains remnants of four separate ancestral diploid subgenomes that underlie strawberry's form and function.

balbisiana. Common cultivated bananas are usually triploid (3n) with three sets of chromosomes. [Note: The word "set" is defined here as one haploid set of chromosomes.]

How many chromosomes do humans have? Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes.
123725
Fruit fly gametes each have four chromosomes, representing 24 or 16, possible chromosome combinations.

The chromosomes under study are taken from the meristem cells of the young growing onion roots. A healthy normal onion cell has 16 (2n = 16) chromosomes.

The fruit fly, Drosophila melanogaster, has a total of eight chromosomes (four pairs) in each of its somatic cells.
265713
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Monkeys, chimpanzees, and Apes have 24 pairs (twenty-four pairs), for a total of 48.

Fruit fly somatic cells have eight chromosomes. During the metaphase stage of mitosis, how many chromatids are there?
615434
Each species has a characteristic diploid number of paired chromosomes. A donkey typically has 62 chromosomes, inheriting 31 from each parent, and a zebra has 44, with 22 coming from each parent.

In a human karyotype, the 46 chromosomes of the human genome are arranged into 23 pairs. Encyclopædia Britannica, Inc. An organism with any multiple of the diploid number of chromosomes is said to be polyploid.
1307787
At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
1251622
Starts with 46 chromosomes in humans and forms haploid cells of 23 chromosomes.

Cytological analysis identified the chro- mosome number of diploid plants of Petunia hybrida as 2n = 2x = 14 (Fig. 1, A3). In two of the tetraploid plants (as identified by cyto- metric analysis), the cells were found to be larger than those of diploid plants with 28 chromosomes in each cell, i.e., 2n = 4x = 28 (Fig.

How many chromosomes does the nucleus of each reproductive cell have in dairy cattle? 37.

How many chromosomes do drones of honey bee possess? Name the type of cell division involved in the production of sperms by them. In honey bees the females are diploid and males are haploid, the males have total 16 chromosomes. The males are developed from unfertilized eggs.

All conifers have twelve chromosomes, but they are extremely large: a cell from a spruce or pine has seven times as much DNA as a human cell does.

In meiosis, a cell containing the diploid number of chromosomes is converted into four cells, each having the haploid number of chromosomes. In human cells undergoing meiosis, for instance, a cell containing 46 chromosomes yields four cells, each with 23 chromosomes.
