Quantitative features are
- genotypically conditioned by a larger amount of genes with a small effect – polygenes
- genotypically conditioned by a smaller amount of genes with a small effect – polygenes
- genotypically conditioned by a larger amount of genes with a big effect – polygenes
The mass of inheritance and non-hereditary variability
- heritability
- heritage
- variability
Values of h2 lower than 0,2 are regarded as
- low heritability
- high heritability
Values 0,2 – 0,5 are regarded as
- medium heritability
- low heritability
- high heritability
Values over 0,5 are regarded as
- high heritability
- low heritability
- medium heritability
The higher heritability,...
- ...the higher similarity between parents is to be expected
- ...the higher similarity between parents is to be expected
Marks of quantitative genes
- are easily influenceable by factors of the environment
- are not easily influenceable by factors of the environment
Non hereditary variability, changing the phenotype of quantitative features, is called
- modification
- radiation
- mutation
Quantitative feature can be characterized...
- continual variability - Gaussova curve
- continual variability - Jordanova curve
- continual variability - Bézierova curve
By a monogenous feature are formed
- 3 genotypes (AA, Aa, aa)
- 2 genotypes (AA, aa)
- 1 genotype ( AA)
