As a result, there are literally millions of genetic combinations that could result from the fertilization of the pollen with ova. Just like human siblings are not genetically identical,
seeds do not grow into genetically identical plants
.
Are all seeds genetically the same?
Re: Are seeds in the same fruit genetic twins? No, seeds from the same cross-pollinated fruit
are not genetically identical
.
Are all the seeds in an apple genetically identical?
Well, I can't speak to the dna of the actual flesh of a fruit, but I do know that the
seeds of apples are not genetically identical to the seed that produced the
tree from which it is growing, which is why you have to clone apple trees by grafting tree branches to a rootstock.
Are the seed coat and embryo genetically identical?
the
seed coat
is part of the original maternal tissue, while the embryo has only half of the chromosomes of the original maternal tissue. … development of a waxy cuticle to prevent water loss and the development of the seed, a protective covering surrounding the embryo.
Are plants genetically identical?
The body cells of plants and animals are
clones
ultimately derived from the mitosis (cell reproduction) of a single fertilized egg. … Plants that are able to propagate by asexual means produce genetically identical plants that are clones.
Why do apple seeds grow different apples?
There are more than 7,500 known cultivars of Apples. This broad range of varieties arises from
the need of Apples to cross pollinate in order to produce fruit and seed
. Each of these genetic crosses produces a unique set of genes, giving rise to a broad range of cultivars.
Do apples contain DNA?
The apple genome has approximately 57,000 genes
, which was the highest number of any plant genome studied at the time, and more genes than the human genome which has about 25,000 genes. … Apple color is important when it comes to consumer preference, and red apples are generally preferred.
What is inside a seed?
Seeds have a seed coat which protects them while they grow and develop, usually underground. … Inside the seed there are is
an embryo (the baby plant) and cotyledons
. When the seed begins to grow, one part of the embryo becomes the plant while the other part becomes the root of the plant.
Which part of a seed stores the baby plant?
Inside the seed there are is an
embryo
(the baby plant) and cotyledons. When the seed begins to grow, one part of the embryo becomes the plant while the other part becomes the root of the plant. Food for the plant is stored in the cotyledons.
What does a seed need to germinate?
The beginning of the growth of a seed into a seedling is known as germination. All seeds need
water, oxygen and the right temperature
to germinate.
Why is plant cloning bad?
Here are some demerits of cloning a plant.
Genetic diversity is adversely affected due
to cloning. … Cloned plants cannot withstand changing environmental factors and if a disease strikes even a single cloned plant, it can wipe out the entire crop.
Why are plants not identical?
‘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.
Why are plants easier cloned?
Some plants like tomatoes are easy to clone because
they possess lots of natural auxins hormones
while others are challenging to do without using an added hormone. The rooting hormones help stir the plant cell growth and establish roots faster.
Why can't you grow an apple tree from seed?
It is possible to grow an apple tree from an apple seed. However, in most cases,
apple trees don't come true from seeds
. … Apple seeds need to be exposed to cool, moist conditions before they will germinate. The cool, moist requirement can be accomplished by planting apple seeds outdoors in fall.
Why are apples not true seed?
Apples do not reproduce true to type
, meaning that the tree grown from a specific variety of seed will produce apples almost certain to be different than the parent. You can have fun and experiment, but don't expect to have the same fruit. Also, almost all varieties are unable to pollinate themselves.
Can you plant apple seeds from store bought apples?
The short answer is:
Yes
, but… Many of the apple varieties in grocery store bins are hybrids because apples do not reproduce true to type. … Starting with seeds from apples that have been grown in your region may increase the chance of success.
