Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

A. What traits are controlled by the branching gene and fruitcase gene? And how were they determined to be major players in the development of maize? B. Teosinte looks like a terrible plant to begin to domesticate for agricultural purposes. What hypothesis is put forth to explain farmers’ early interest in the plant? C. Often successful domestication of a plant or animal is due to the fact that this involved just a few gene changes. In what situation can changes in just a few genes dramatically change an organism's entire appearance? D. Who is Norman Borlaug?

cyndi grows thousands of b.rapa plants from seed and carefully watches for any unusual plants that might be a new mutation. she has been watching a small seedling whose leaves continue to develop, but the stem is not elongating. The result is a cluster, or rosette of leaves sitting just above the soil surface. After 15 days the plant is beginning to produce flowers but is still a rosette Cyndi is encouraged and hypothesizes that rosette is a recessive mutation. describe the first cross she should make and the predicted result.

A paper hypothesizes that white flowers are unable to produce anthocyanins (purple pigments) because they lack a functional “A” protein. However, it is also possible that an unknown gene is responsible for the lack of anthocyanins. Now that they have isolated DNA sequences of the “A” allele, design an experiment to use these DNA sequences to distinguish between these two hypotheses.

In plants, floral organs develop from concentric rings of tissue called whorls. Beginning from the most outside ring, whorl 1 develops into sepals, whorl 2 develops into petals, whorl 3 develops into stamens, and whorl 4 develops into carpels. Analogous to the homeotic mutants of Drosophila, recessive mutations were found in genes that encode transcription factors. These mutants change the organ identity of a given whorl to the identity of a different whorl. The following table shows the mutant phenotypes caused by various floral organ mutations found in the genetic model plant, Arabidopsis. Genotype wild-type ap2 lap2 ap3 lap3 ag lag sepals carpels sepals sepals whorls 2 and 3 whorls 3 and 4 whorls 1 and 2 whorls 2 and 4 All four whorls 1 petals stamens sepals petals Based on the table above, which whorls require a functional AG gene. 2 Whorl stamens stamens carpels petals 3 carpels carpels carpels sepals 4
In comparison to experimental results from the genetic manipulation of an invertebrate model, what pathologic outcome(s) would suggest that multiple homologs of a disease gene are present in humans? a. Missing the essential gene homolog that is lethal in fruit flies is also lethal in human infants. b. Different homologs of the essential gene are each expressed in different human organs, and mutations in these duplicated genes cause organ-specific diseases. c. Different homologs of the essential gene are each expressed in different stages of early child development, and mutations in each of these duplicated genes cause different diseases. d. In humans, defects in different homologs of the essential gene cause different loss-of-function diseases due to subfunctionalization. e. The essential gene is lethal in fruit flies, but there is no disease phenotype exhibited in people.
