<span>Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span>
<h3>Answer:</h3>
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
Explanation:
For example, if the Earth is pulling down on you with a gravitational force of 500 N, you are also pulling up on the Earth with a gravitational force of 500 N. ...
Answer:
Explanation:
The history of humanity from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human bieings that we are today evoled from many years ago some say from the begining of time— it is connected to climate variation and change. Human biens has experienced nearly two full glacial-interglacial cycles, but its global geographical expansion, massive population increase, cultural diversification, and worldwide ecological domination began only during the last glacial period and accelerated during the last glacial-interglacial transition. The first bipedal apes appeared in a time of climatic transition and variation, and Homo erectus, an extinct species possibly ancestral to modern humans, originated during the colder Pleistocene Epoch and survived both the transition period and multiple glacial-interglacial cycles. Thus, it can be said that climate variation has been the midwife of humanity and its various cultures and civilizations.
Answer:
The correct answer is - AABb/AaBb : aaBB/Aabb would be 1:1.
Explanation:
The cross between AaBb and AAbb will produce AB, Ab, aB, aB and Ab, Ab, Ab, Ab gametes respectively. These gametes from zygote and produce the two phenotypic character one with AABb/AaBb and aaBB/Aabb. The first phenotype would have both dominant traits while in others have only A dominant and B recessive in the phenotype of offspring.
Thus, the correct answer is - AABb/AaBb : aaBB/Aabb would be 1:1.
