The Order of Genes on a Plant Chromosome Is A

question 47

Multiple Choice

The order of genes on a plant chromosome is A, B, and D, where A and B have a recombination frequency of 0.2, and B and D have a recombination frequency of 0.3. A pure- breeding plant that has the dominant A and D phenotypes with a recessive b phenotype is crossed to a pure- breeding plant that has the recessive a and d phenotypes with the dominant B phenotype. The resulting hybrid is crossed to a plant that has all three recessive phenotypes. Under the assumption that the value for interference in this region is zero, what percentage of each progeny type would result from a single crossover between B and D?

• A) 50% AbD/ abd; 50% aBd/ abd
• B) 24% ABd/ abd; 24% abD/ abd
• C) 7% ABD/ abd; 7% abd/ abd
• D) 12% Abd/ abd; 12% aBD/ abd
• E) 9% ABD/ abd; 9% abd/ abd

Core-Mantle Boundary

The interface between the Earth's outer core and the mantle, characterized by a significant change in seismic wave velocities and an important zone for understanding the internal structure and dynamics of the Earth.

Atmospheric Pressure

Atmospheric pressure is the force per unit area exerted against a surface by the weight of the air above that surface in the Earth's atmosphere.

Altitude

the height of an object or point in relation to sea level or ground level.

Ozone Content

The concentration of ozone molecules, typically referenced in the context of the Earth's stratosphere where the ozone layer protects life by absorbing harmful UV radiation.
