Q205
The ratio of genotypic covariance to the phenotypic covarience is known as
A.
Inbreeding depression
B.
Heritability
AnswerC.
Heterosis
D.
Variation
Answer: Option B
Solution
Answer: Option B
Solution:
The ratio of genotypic covariance to the phenotypic covarience is known as Heritability.Heritability is the ratio of genetic variance (VG) to phenotypic variance (VP) and ranges from 0 to 1.
High heritability values of 0.5 mean that on average half of the differences among phenotypes of animals are genetic. Low values of approximately 0.1 mean that most of the differences are not genetic.
