The Basalt Seed Lending Library run by the Central Rocky Mountain Permaculture Institute and the Basalt (Colorado) Regional Library (see Experimental Insight
The many different types of seed produce plants and vegetables that consistently have specific traits. Give a genetic explanation for the consistent production of the same traits from plants grown from heirloom seeds.
A goal of the seed-lending program over time is to generate seeds and plants that thrive and yield better harvests. From an evolutionary perspective, explain how saving and replanting seeds from the most productive plants each year contributes to this goal.

(b) A plant breeder wants to use selective breeding to produce corn with short stalKS
and a high mass of grain. He could use the following varieties of com:
varlety A
varlety B
varlety C
long stalks
short stalks
long stalks
high mass of grain
low mass of grain
low mass of grain
(i) What would the plant breeder need to do to make sure he always
produced corn with short stalks and a high mass of grain?
Describe the three steps the breeder would use.
(ii) Suggest one other characteristic that famers might like corn plants
to have to increase the amount of corn produced.
In general, larger plants have larger organs. So, one option for increased yields is to breed and grow for the largest size possible. However, there are practical reasons to growing smaller plants. What are some drawbacks to breeding and growing increasingly large plants? List and briefly explain two possible reasons.
What specific RIM is being described by each of the following statements?Explain your answer in each letter
_______E) Offspring of hybrid cotton (genus Gossypium) plants either die during early development or grow into unhealthy plants.

- Before, plant breeding was done by crossing the genes of two plants with desirable characteristics. This technique has been successful in producing improved varieties of crop plants, but it is time consuming and complicated. Because of genetic engineering, these problems can now be avoided. Plants are inserted with "super" genes to exhibit improved or better traits compared to their ordinary counterparts. These plants are therefore called transgenic plants.

- Figure 19-16 shows the results of a QTL fine-mapping experiment. Which gene would be implicated as controlling fruit weight if the mean fruit weight for each linewas as follows?Line Fruit weight (g)1 181.42 169.33 170.74 171.25 171.46 182.27 180.68 180.79 181.810 169.3arrow_forwardDifferent traits may be important in order to increase wheat yield. These traits may include short plant height, short and erect leaves, large and compact panicles, and resistance to shattering. Resistance to shattering is an important agronomic character for maximizing wheat yield, because plants with low susceptibility to shattering have reduced loss of grain mass during harvest. If you have determined that VG = 357, VD = 52, VI = 24 and VE = 5 for the shatter trait, what is the estimate for narrow sense heritability for the shatter trait?arrow_forwardDrought is one of the major problems which cause serious yield reduction in wheat crop.

Determine the ratios for phenotype and genotype of each Punnett Square.You may use the example from the Punnett Square worksheet as a guide.A genetic engineer is going to cross two watermelon plants to produce seeds for spring planting. He is breeding for size and wants to have many watermelons with the phenotype for long shape as possible. In watermelons, the allele for short shape is (S) is dominant to the allele for long shape. Determine the Genotypic ratios and phenotypic ratios for each Punnett square. Which cross would yield the highest number of long watermelons?

A team of biologists is trying to determine the potential forrapid evolutionary responses of plants to changing seasonal conditions. They do alaboratory selection experiment on flowering time in an annual plant to test for the presence ofadditive genetic variance for this trait. They measure the time between germination andflowering for 400 plants under controlled laboratory conditions and then use 25% with theshortest flowering times to find a second generation in the lab (with pollination based onrandom number sampling). The mean flowering time for the overall parental population was 80days. The mean for the selected 25% of individuals was 60 days. In the offspring generation, themean flowering time was 70 days. 6a.

Explain your answer in briefly.arrow_forwardFrom an agricultural point of view, discuss the advantages and disadvantagesof selective breeding.
