Are seeds from the same fruit genetically identical?
I imagine there is a great deal of genetic variation in pretty much any pomegranate variety. Some plants do produce twin seeds, called polyembryonic. They are easy to recognize since you will see two embryos inside one seed coat (try opening some mango seeds and you’ll almost certainly find some like this).
Will the fruits always have the same number of seeds?
Not all fruits contain the same number of seeds. Fruits such as tomatoes, cucumbers, green peppers, and melons usually have lots of seeds. Generally, oranges, apples, and pears contain about 10 seeds. Other fruits, such as avocados, plums, and peaches, have only one seed.
Why will the new plant look the same as the original plant?
Hybrids result from crossing two different inbred lines. All of the first generation of plants from this cross will contain the exact same two sets of genes (one from each line) and thus will be identical to each other.
What fruits are not true to seed?
Apples and pears are never true to seed but tamarillos can be grown from seed. Apricots, peaches and nectarines grow fairly true to seed, some say plums do too. They wont be exact but often quite close.
Are all seeds genetically different?
No, the seeds are not genetically identical. Each seed come from the fertilization of an ovum with a sperm from a separate pollen grain. Since each pollen grain can come from a different plant, the seeds will generally differ from one another.
Are all seeds the same?
Most plants produce seeds of some kind, but not all seeds are alike. Nature not only has given them different sizes, shapes, and colors, but also has packaged them in any unique ways. Some are found inside soft, fleshy coverings.
Why do different plants have different number of seeds in their fruits?
Number of seeds in a fruit depends on the number of ovules in an ovary before fertilisation. The fruits which have more seeds in them have more number ovules in the ovary of flowers such as watermelon and those with single seed have only single ovule in the ovary of flowers like mango.
Why do different plants have different number of seeds?
As the ovary turns into fruit, different ovary parts become different fruit parts; when fertilized, small structures called ovules become the fruit’s seeds—and more fertilized ovules means more seeds! The other two fruit groups are more complex.
How is it possible for plants that have identical genetic makeup to show differences?
water, the nutrients available or lacking in the soil, and the treatment given to a plant affect its phenotype. Thus, two genetically identical plants in different environments will show differences.
Why do plants do not look exactly alike?
‘But sometimes regenerated plants are not identical, even if they come from the same parent. They found that observable variations in regenerant plants are substantially due to high frequencies of mutations in the DNA sequence of these regenerants, mutations which are not contained in the genome of the parent plant.
Is Apple true to seed?
Apples do not come true from seed. Actually about 1 in every 80,000 apple trees grown from seed is quality factors good enough to even be considered for evaluation. The bud grows out and becomes the top of the new tree.
Do tomatoes grow true?
Open pollinated strains of tomato exist, which will come true to type, although “type” will be more genetically diverse than close-pollinated strains. As for your particular plant – viruses can pass onto seeds (depending on where they are distributed) which could, therefore, affect the offspring.
