AVprozaik [17]

Answer:

Starfish reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.

In ducks, the trait for normal feathers is dominant to the trait for silky feathers. If

vesna_86 [32]

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.
