Explain the benefits of tiger in a dense forest for variation. How can you assume about dominant recessive homozygous-heterozygous and pure hybrid organism from a genetic cross.

A uniform magnetic field of 100 G (IG=10^(-4)T) exists in a region of length about 10 cm and area of cross- section about 10^(-3)m^(2) . The maximum current carrying capacity of a given coil of wire is 15A and the number of turns per unit length that can be wound round a core is at most 1000 turns m^(-1) . How would you utils the coil to design a solenoid for the required purpose ? Assume the core is not ferromagnetic.

According to Mendel what do you mean by dominant and recessive character in monohybrid cross? Evaluate how genetic counselling can help a man to take right decision before and after marriage.

Mendel crossed a pure white -flowered recessive pea plant with a dominant pure red-flowered plant .The first generation of hybrid from the cross should show
