Happy homework/ study/ exam!
Answer:
7/16
Explanation:
<em>The proportion of the offspring from the cross that will have white flowers is 7/16.</em>
The presence of anthocyanin which determines purple coloration is conditioned by the C_ and P_ alleles. It means that the absence of one or both of C and P will result in white flowers.
Two plants, each with CcPp are crossed:
CcPp x CcPp
Offpring
1 CCPP - purple
2 CCPp - purple
2 CcPP - purple
4 CcPp - purple
2 Ccpp - white
1 CCpp - white
1 ccPP - white
2 ccPp - white
1 ccpp - white
Proportion of offspring with white flowers = 7/16
Proportion of offspring with purple flower = 9/16
<em>See the attached image for the Punnet's square analysis of the cross.</em>
<u>Answer</u>:
Concave shape of the wave rock is a physical evidence that supports the evolution of earth due chemical weathering
<u>Explanation</u>:
It is the best physical evidence of collection in the earth’s evolution. The earth surface is 2.7 billion years old, also the basis for formation of Australian continent formation. The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history.
Answer:
A) hybridization; morphospecies
Explanation:
The biological species concept is the concept which can define a species as an individual of a large population which can interbreed and produce an offspring in a population. The concept was given by Ernst Mayr.
Morphospecies refers to the species which can be characterised by the differences in their morphological features like in the Oak, willows and the dandelions.
The biological species concept is not valid or complicated in the case of the morphospecies like in the Oak, willows and the dandelions as the individuals of these three population can exchange their genes through the process of hybridization.
Thus, Option-A is the correct answer.
