aliina [53]

Explanation:

50%; homozygous recessive; phenotype

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

A negative choice to make to impact one's health is to constantly over-think situations, causing stress and an unhealthy state of mind.
