According to the Punnett square, offspring from these two parents have a 50%chance of inheriting two b alleles. Individuals that inherit two b alleles are homozygous recessive . Inheriting two b alleles confers the phenotype of blue eyes.

Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For instance, co-dominance, both of a gene's alleles are present, and notable in the phenotype.

The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.

The magnitude of an earthquake is a number that represents the what

Llana [10]

One useful point about the moment magnitude scale is that it is logarithmic, where each whole number represents a factor of 32. Therefore, the difference in two whole numbers of the magnitude means that an earthquake is 1,000 times stronger. For example, a 7.0 magnitude earthquake releases 1,000 times more energy than a 5.0 one.
