Answer:
Both "D" and "d" allele
Explanation:
As per the principle of segregation proposed by mendel, an allele pair can split in to two during cell division in a way such that it can give both of its allele (with in an allele pair) to its offspring.
Thus by that logic anyone with a genotype Dd, can segregate its allele pair to pass both "D" and "d" allele to its offspring.
Sam (father) DD homozygous dominant
Sally (mother) dd homozygous recessive

Explanation;
Scientific experiments are conducted to figure out answer and solve a problem and get info about hypothesis.
-Scientific methods involvesobservation, developing questions, formulating hypothesis, making an experiment, collecting data and analyzing results, making a conclusion, and communicating results.
Answer:
A.
Explanation:
Answer:
Pleiotropy is the answer you're looking for :)
Pleiotropy occurs when one gene will code and control the phenotype or expression of several different and unrelated traits.
B. Photosynthesis
C. Decaying organisms
D. The gases in the atmosphere
Answer: A. Positive ions
An ocean is a reservoir of carbon. All of the following bring carbon into the ocean except positive ion:
Photosynthesis: Photosynthesis is conducted by aquatic plants in the ocean to prepare their food which is a carbon product.
Decaying organisms: The aquatic plants and animals are buried beneath the ocean bed and they are decayed and decomposed by the activity of microbial organisms. The organic matter produced after this process is rich source of carbon.
The gases in the atmosphere: The gases in the atmosphere consist of carbon dioxide and carbon monoxide released in the atmosphere by burning of fossil fuels, greenhouse gas emission and by other process. These gases are dissolved into ocean water making it available for photosynthesis conducted by aquatic plants. Hence, carbon from the atmosphere enters in ocean through these atmospheric gases.
