Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.
Answer:
Amino acids
Explanation:
Nitrogen is a major part of amino acids. Which are the building blocks of proteins and nucleic acids.
A compound consists of two or more elements.
Answer:
.Mating systems are important to understand because they reflect the result of natural selection on mate choice, and ultimately on strategies for maximizing individual reproductive success
Explanation:
Indiana's climate changed due to increased amount of carbon dioxide in the atmosphere.
