Answer: The genotype ratio is 2Ff : 2ff
The phenotype ratio is two normal feathered birds to two silky feathered birds.
Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.
A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.

Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.
How was Bohr's atomic model similar to Rutherford's model?
it described a nucleus surrounded by a large volume of space.
The Mantella frog of Madagascar and the poison dart frog of South America share the same characteristics but they live in different ecosystems. The two frogs live in the same type of niche, eat the same type of food and have similar defense mechanisms. Therefore, if a group of mantella frogs are transported to the ecosystem of the poison dart frogs, the two populations will be involved in competitive exclusion, that means that, both frogs will fight for the same resources and the better suited frog will survive. Thus, the population of the ill suited frog will decrease.
