Answer:

Explanation:

Valence electron may be defined as the electrons present in the outermost shell. The valence electron has the ability to lose or gain the other electron and also determines the chemical property of the element.

The outermost electrons can be calculated by looking at the outermost shell. In the given example 1s22s22p63s23p4, the number of valence electrons are 6 ( the sum of electron present in the 3s and 3p orbitals.

Thus, the correct answer is option (1).

Sindrei [870]

Answer:

The predicted genotype of the offspring is GgRr.

Explanation:

The gray body is dominant over black body. The genotype of gray body is GG and the genotype of black body is gg. Red eyes are dominant over orange eyes. The genotype for red eye is RR whereas the genotype of orange eye is rr.

GGRR is crossed with ggrr, the offspring produced by this cross is GgRr with gray body and red eyes.

GGRR × ggrr

GgRr.
