In a cladogram, when does a group of organisms branch off? when a new trait evolves when an ancestor becomes extinct when it is discovered when it becomes large enough
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:
Now i know that natural resources are important because they are used to make our food and fuel. all of the food we eat comes from plants and animals and if we didnt have plants or animals we wouldnt exist right now. natural resources are important also because they make our fuel and they provide heat, light, and power. they are the main thing we need to survive. we have to protect and conserve natural resources!
