The requirements for long-term storage of its seed and pollen are known. The tomato possesses a haploid set of 12 chromosomes, each of which can be identified at pachynema by relative arm lengths, distribution of the highly distinguishable heterochromatin and euchromatin, and other cytological landmarks.
How many chromosome does a tomato have?
Tomato (Solanum lycopersicum L.) is the most intensively investigated Solanaceous species both in genetic and genomics studies. It is a diploid species with a haploid set of 12 chromosomes and a small genome (950 Mb).
How much DNA is in a tomato?
The tomato, whose genome has just now been decoded, turns out to be one well-endowed vegetable, possessing 31,760 genes.
How many chromosomes are in a daughter cell of a tomato?
Terms in this set (16)
Diploid tomato cell has 24 chromosomes in the nucleus.
What is the scientific name of tomato?
Tomato (Solanum lycopersicum)
How many diploid chromosomes are in a tomato?
The recognized chromosome number of tomato has been 2n = 24. In this paper the chromosome number 2n = 26 is reported in 18 varieties of tomato. One commercial hybrid variety, revealed 25 mitotic chromosomes. This variety, as well as the varieties with 26 chromosomes, appeared to be fully fertile.
How many chromosomes does a strawberry have?
The strawberry genus, Fragaria (Rosaceae), has a base chromosome number of x = 7. Cultivated strawberries (F. ×ananassa nothosubsp. ananassa) are octoploid (2n = 8x = 56) and first hybridized from F.
Do all tomatoes have genes?
Scientists have described the genetic underpinnings of 100 different types of tomatoes. A new analysis of genetic variation in tomatoes has uncovered more than 230,000 previously hidden, large-scale differences in DNA among varieties. As tomato plants evolved, segments of DNA were deleted, duplicated or rearranged.
What genes are in tomatoes?
|Gene symbol||Locus||Defined function/associated fruit phenotype (+ or −)a|
|SlIAA9||Solyc04g076850||Auxin signaling/parthenocarpy (−)|
|SlARF7||Solyc07g042260||Auxin signaling/parthenocarpy (−)|
|SlTIR1||Solyc09g074520||Auxin signaling/parthenocarpy (+)|
|AUCSIA1||Solyc10g054660||Auxin signaling/parthenocarpy (−)|
Where is the DNA of a tomato?
At the layer between the tomato juice and alcohol you will see a whitish, “snotty-looking”, substance. This is DNA.
How many chromosomes are in each resulting cell?
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
How many chromosomes does each new daughter cell contain if the parent cell has 24 chromosomes?
Complete answer: If a cell has 24 chromosomes and it undergoes mitosis to create two cells, then the daughter cells also have 24 chromosomes each. Mitosis is a process of division of cells where a parent cell divides into two daughter cells each of which is genetically just like the parent cell.
How many chromosomes are in a cell after mitosis?
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.
Why tomato is red?
As the tomato ripens, its colour starts to change from green to yellow and then eventually to red. This is due to the breakdown of chlorophyll, which in turn synthesises a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid can easily be seen as the dominant colour of the tomato, ie red.
What class is tomatoes?
In what family tomato belongs?
tomato, (Solanum lycopersicum), flowering plant of the nightshade family (Solanaceae), cultivated extensively for its edible fruits.
