To find a gene, you have to associate a phenotype with a genotype (e.g. all individuals with white flowers have a certain allele). It is MUCH harder to find genes that are involved in polygenic traits than it is to find the genes responsible for discrete traits. Why? What is genetic recombination?

1)How is polygenic inheritance defined?

To find a gene, you have to associate a phenotype with a genotype (e.g. all individuals with white flowers have a certain allele). It is MUCH harder to find genes that are involved in polygenic traits than it is to find the genes responsible

for discrete traits. Why?

What is genetic recombination?
How is it possible for offspring to have different phenotypes from their parent, even when 1) self-fertilization occurs, 2) there is no crossing over, and 3) no mutation occurs?
What does it mean to say that an individual outcrosses?
When homologs synapse in prophase of meiosis I, crossing over occurs in both

pairs of non-sister chromatids, but at different locations. In terms of generating genetic variation, why is this significant?

How does independent assortment create genetic variation?
How does crossing over and recombination create genetic variation?
How does outcrossing create genetic variation?

Monozygotic twins occur when a fertilized egg undergoes mitosis, and the two cells that result become separated and develop independently. What is the genetic relationship between the two offspring?
