Answer:
<u><em>Genetic variation</em></u> occurs because beneficial traits exist in a collection of genes, and <u><em>gene flow</em></u> makes these traits more prevalent in populations.
Explanation:
In biology, genetic variation can be described as the different genotypes which occur in species of the same kind. This genetic variation allows those organisms to survive on Earth which are better adapted to survive to the environmental changes.
The organisms which are better adapted to live in an environment will reproduce and pass their traits to the offsprings. Over time, these traits will become more prevalent in a population.
Answer:
Overconsumption of resources, that makes the most sense to me. Hope this helps!
Answer:
3. CABD
Explanation:
The gene mapping refers to providing position to the genes on the chromosomes. The first gene map was constructed by the Alfred Sturtevant on the basis of recombinant produces or recombination frequency which was calculated.
The gene mapping refers to providing position to the genes on the chromosomes.
In the given question to construct gene map:
1. Look for the highest recombination frequency that is 50% between the C and D.
2. Now look for second-highest value and place the gene accordingly.
3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.
Thus, Option-3 is correct.
Sorghum and millet are the grains that thrive well in arid environments. Sorghum is a close relative of the smaller millet, with the latter measuring only a third in size to sorghum. It is important to know that sorghum is sometimes called great millet.
Every 192 -gram cup of cooked whole sorghum or millet contains 22 grams compared to wheat (16 grams), brown rice (15 grams), and maize (16 grams).
