16 Questions
What is the difference between genetic and genomics?
Genetic focuses on single genes, while genomics focuses on whole genomes.
What is the significance of QTL analysis in genomics?
QTL analysis is a way to look at genomes and can help identify genetic loci contributing to variation in traits.
How does the genetic makeup of the F1 generation differ from the parents in a cross?
The genetic makeup of the F1 generation is a half-way house between the parents.
What happens in the F2 generation in terms of genetic recombination?
In the F2 generation, there is limited recombination, and the genomes are in chunks.
What is the significance of studying the F2 generation in genetic analysis?
Studying the F2 generation reveals complex genetic interactions and the basis of complicated traits.
Explain the significance of divergent flower color types in monkey flowers.
Divergent flower color types in monkey flowers demonstrate the genetic basis of the trait, leading to wacky variations in the F2 generation.
What does the observation that all F1 offspring look like the middle parent suggest about the trait being studied?
It suggests that the trait is controlled by a single locus with only two alleles.
What genetic marker was used to study the association with genetics in the F2 generation?
Microsatellite genetic marker.
What gene, when mutated, causes the absence of sweat glands or body hair in humans and mice?
The eda gene.
What did the gel electrophoresis of eggs from a family of stickleback reveal about their plating genes?
It showed that all the eggs had the low plated gene.
What did the study of beak variation in great tits reveal about the association between genotype and beak size?
It revealed that certain genotypes at a specific locus were associated with shorter or longer beaks.
What is the relationship between the genotype at the collagen gene locus and beak size in great tits in the UK?
The TT genotype is associated with shorter beaks, while the CC genotype is associated with longer beaks.
What were the contrasting findings regarding the association between genotype and fitness in great tits in the UK and the Netherlands?
In the UK, the TT genotype was associated with fewer offspring fledged, while in the Netherlands, this was not true.
What are the three important processes mentioned in the text in relation to the study of coat color variations?
Selection, rate of recombination, and conspicuousness.
What did the study of mice on white sands in America reveal about their coat color and predation?
When conspicuous, the mice were more likely to be attacked.
What did the study of mice in the forest and on white sands reveal about their coat color and predation?
Mice on white sands were sand-colored and more likely to be attacked, while those in the forest were darker and less likely to be attacked.
