Explanation:
mostly due to the fact that they are competing over the same food source, which is always limited in some way.
Answer:
25%
Explanation:
The correct answer to the given question is 25%
A sunflower seed contains 9mg of sodium in it which can be modified and reduced as per needs.
If seed of a sunflower is modified and labeled as reduced sodium than this means that the sodium in the seed of a sunflower is reduced by 25% as compared to the original seed of sunflower in which no changing was made.
Eukaryotic cells are cells that have a nucleus, while prokaryotic cells do not.
Answer:
Testcrosses clarify linkage because each phenotypic class of progeny corresponds to each gamete type produced by the dihybrid parent.
Explanation:
- A test cross involves the crossing of an individual with another phenotypically recessive individual so as to determine the zygosity of the former by analyses of the proportions of offspring phenotypes.
- In order to determine linkage, the test cross shows that if the parentals are more than the recombinants, we can say that the two genes such as b and c are genetically linked and therefore, they must be on the same chromosome.
- Also, the test-crosses help to find out which alleles came from which parent.
- By setting up testcrosses in which one parent is homozygous for the recessive alleles of both genes,we can analyze the gene combinations received in the gametes from the other, doubly heterozygous parent.
<span>The woolly lousewort has dense hairs that surround its flowers. These hairs trap the heat from the sun and allow its temperature to be maintined, keeping the flower at a warm enough temperature for it to germinate its seeds.
