It depends on the alleles inherited from the parents. If dominant and recessive allele were inherited from each parent you have 1 offspring that has 2 dominant alleles, 1 offspring that has 2 recessive alleles and 2 offspring that has both a dominant and recessive allele. The example below shows (T) as dominant allele and (t) as the recessive allele. The bold letters represent the parent alleles that the parents passed on to offspring.
T t
T TT Tt
t Tt tt
Explanation:
A new study on the socioeconomic impact of the Gautrain indicates that the rapid-rail system adds R6. 64-billion to the Gauteng economy's gross domestic product (GDP) – or 0.56% – during a typical year of operation. Carbon emissions from the Gautrain are considerably lower per passenger transported than for private vehicles, notwithstanding the higher speeds and even when there are no major traffic incidents. Energy use by rail is three to five times more efficient than cars per person kilometer based on full capacity.
