Answer:
Due to large size of genome.
Explanation:
The study of wheat genome is difficult task because of its large size. The genome of wheat comprise of 15 billion DNA bases. The wheat genome is three times bigger in size as compared to the genome of mammoth. Mammoth is an extincted specie of elephant which were the biggest land animal at that time. So due to large genome size of wheat, the scientists takes more time to complete its sequencing (order of nucleotide in the DNA).
Human gestation time is 40 weeks or 280 days
Answer:
Without Earth's magnetic field, solar winds — streams of electrically charged particles that flow from the sun — would strip away the planet's atmosphere and oceans. As such, Earth's magnetic field helped to make life on the planet possible, researchers have said.
Explanation:
Hope this helps.
<span>The carbon dioxide level in the city will be higher because the exhaust gases from vehicles release carbon dioxide and there are not many trees to utilize it.
Plants go through photosynthesis using carbon dioxide, releasing oxygen in the process, so more of the carbon dioxide is used in the garden. Plus, there is more carbon dioxide in the city to begin with, simply because there are more vehicles with more exhaust.</span>
Answer:
d. all of the offspring have medium length fur.
Explanation:
Incomplete dominance is a phenomenon in which offspring produce a trait that is intermediate between the two forms of a certain trait.
For example: In four o clock plant, some plants produce red flowers while some plants produce white flowers. When plants with red flowers are crossed with plants with white flowers, all the offspring have pink flowers.
Why is that so?
This is because no allele is completely dominant over the other and therefore both contribute their individual effect by producing intermediate phenotype.
Example in question:
Cross between a rabbit with short fur (SS) and a rabbit with long fur (LL)
P1: SS x LL
Gametes: S and L
Offspring SL :SL
SL: Medium length fur
Therefore this is a case of incomplete dominance.
Hope it help!
