7. What is true about the strategy of selective breeding?
Choosing parents with the best
Choosing parents with the greatest number of alleles to pass them to their offspring
Choose parents with best alleles to pass them to their offspring
Choosing parents with the best genotypes to pass their alleles to their offspring.
8. What best describes the relationship between genetic distance and frequency of recombination?
Genes that are far apart have a 50% crossover rate
The closer are the genes, the less crossover there is between them
Double crossover makes the estimation of genetic distance difficult
Crossover is the best way to estimate the genetic distance
9. You have a population of sheep; You want to start a selection program to maximize production of wool. What is the phenotypic feature that you would consider to pick the parents of the breeding program? Explain.
10. The difference between a substitution and a deletion is that a substitution exchanges one base for another and a deletion replaces an excised base with another.
True or false?
11. What portion of the phenotypic variation of a trait does narrow-sense heritability h2 reflects in a population?
All the genetic effects controlling the trait
The additive allelic effects and epistasis of the genes controlling the trait
The additive allelic effects of the genes controlling the trait
