In Mendel’s experiment, nature of seed coat, flower colour, position of flower, pod colour, stem height, etc. are referred to as: Alleles Phenotypes Genotypes Traits

According to Mendel’s monohybrid cross, the characters which appears in F1 is said to be: Recessive Co-recessive Dominant Partially dominant

Transposons are capable of moving from one site in DNA sequence to other mostly: On same chromosome On homologous chromosomes Randomly On non-homologous chromosomes

An allele is said to be dominant if: It is expressed only in heterozygous combination It is expressed only in homozygous combination It is expressed in both homozygous and heterozygous condition It is expressed only in second generation

F1 hybrid is intermediate between the two parents. The phenomenon is: Over-dominance Complete dominance Co-dominance Incomplete dominance

The reverse process of photo electric effect is annihilation of matter pair production production of x-rays nuclear fission

When monochromatic light falls on photosensitive material, the number of photoelectrons emitted per second is n and their maximum kinetic energy is Kmax . If the intensity of the incident light is doubled, then. both n and Kmax are doubled both n and Kmax are halved n is doubled but Kmax remains the same Kmax is doubled but n remains the same

The reverse process of photo electric effect is annihilation of matter pair production production of x-rays nuclear fission

Which of the following is NOT evidence for the wave nature of matter? The diffraction pattern obtained when electrons pass through a slit Interference of light The photoelectric effect The validity of the Heisenberg uncertainty principle.
