Answer:
c. Aa Bb
Explanation:
The parents were pure breeding with genotypes AAbb and aaBB. A cross between AAbb and aaBB would produce AaBb genotypes in F1 progeny. Two F1 strains would be crossed to produce F2 progeny. The F2 progeny would have the genotype ratio= 1:2:1:2:4:2:1:2:1.
Out of all the obtained genotypes in the F2 generation, the proportion of "AaBb" genotype was 4/16. Therefore, "4" in the given ratio represents the genotype "AaBb".
The least dense layer of the atmosphere is the exosphere as it is the outer most layer of the atmosphere. Hope it helps!
According to the cladogram, Osteichthyes belong in group A.
Osteichthyes are a class of fish that have real bones and jaws as derived traits. These derived qualities can therefore be traced backwards from group A, with each line indicating a connection or relationship.
What is Cladogram?
- In cladistics, a cladogram is a diagram that is used to depict relationships between species.
- Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these links. Phylogenies and trees are other names for cladograms.
- A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it. The branches that represent related groups and their shared ancestors are known as clades. The points known as nodes represent the fictitious ancestors.
