GE 02-55 Factors gene fund

What is typical for mutations?
1. standing change of gene fund, formation of new alleles, frequency very low, important by evolution
2. standing change of gene fund, formation of new alleles, frequency very high, important by evolution
3. standing change of gene fund, formation of new alleles, frequency very low, not important by evolution
Natural selection or
1. choice
2. mutation
3. modification
Why is selection high?
1. individuals have more descendants
2. eliminates individuals with disadvantageous mutant alleles
3. individuals have more descendants
Selection counteracts against
1. recessive homozygots
2. dominantním homozygots
3. recessive heterozygots
Migration has
1. similar effect like mutation
2. similar effect like selection
3. similar effect like deletion
Genetic shift or
1. drift
2. deletion
3. combination
Genetic shift
1. they are used in small alogamic populations
2. they are used in small autogamic populations
3. HW law here in force
Relational crossbreed is also called
1. inbreeding
2. intermediary breeding
3. polygamy
Coincidental shift of genetic balance is
1. drift
2. mutation
3. ontogenesis
Enrichment of gene fund by new alleles or on the contrary also its impoverishment
1. migration
2. mutation
3. deletion
