In F_(2) generation of a Mendelian dihybride cross (w.r.t plant height and flower colour in garden pea), _______ % of the zygote contain heterozyogus condition for tallness.

(a) What will you get in the F_(1) and F_(2) generations in the following cross ? Pure tall pea plant x pure dwarf pea plant (b) Is it an example of monohybrid cross or dihybrid cross ?

In a cross between a pure tall pea plant with green pod, and a pure short plant with yellow pod, how many short plants out of 16 you would expect in "F"_(2) generation?

(a) Dihybrid cross between two garden pea plant one homozygous tall with round seeds and the other with wrinkled seeds was carried. (i) Write the genotype and phenotype of the F_(1) progeny obtained from this cross. (ii) Give the different types of gametes of the F_(1) progeny. (iii) Write the phenotypes and its ratios of the F_(2) generation obtained in this cross along with the explanation provided by Mendel. (b) How were the observations of F_(2) progeny of dihybrid crosses in Philosophical by Morgan different from that of Mendel carried in Pea plants ? Explain giving reasons.

The Alaska pipeline starts at the frozen edge of the Arctic Occan. It stretches southward across the largest and northernmost state in the United States . ending at a remote icefree seaport Village nearly 800 miles from where it begins . It is massive in size and extremely. complicated to operate. The steel pipe crosses windswept planins and endless miles of delicate tundra that tops the frozen ground . It weaves through crooked canyons , climbs sheer monuments , plunges over rocky crags , makes its way through thick forest , and passes over or under hundreds of rivers and streams . The pipe is 4 feet in diameter, and up to 2 million barrels (or 84 million gallons ) of crude oil can be pumped through it daily. Resting on H - Shaped steel racks called" bents". long sections of the pipeline follow a zigzag course high above the frozen earth . Other long sections drop out of sight beneath spongy or rocky ground and return to the surface later on. The pattern of the pipeline's up and down route is determined by the often harsh demands of the arctic and subarctic climate , the tortuous lay of the land , and the varied composition of soil, rock, or permafrost ( permanently frozen ground) . A little more than half of the pipeline is elevated above the ground. The remainder is buried anywhere from 3 to 12 feet , depending largely upon the type of terrain and the properties of of the soil. One of the largest in the world , the pipeline cost approximately $8 billion and is by far the biggest and most expensive construction project ever undertaken by private industry. In fact , no single business could raise that much money , so 8 major oil companies , formed a consortium in order to share the costs. Each company controlled oil rights to particular shares of land in the oil fields and paid into the pipeline construction fund according to the size of its holdings. Today, despite enormous problems of climate, supply short - age , equipment breakdowns , labour disagreements , terrain, a certain amount of mismanagement , and even theft , the Alaska pipeline has been completed and is operating. How was the fund for pipeline construction generated ?
