How can the two chromosomes that make up a homologous pair differ

Biology

Hi!

Two chromosomes that make up a homologous pair can differ. The reason why they would differ is because they contain different alleles for the same trait. 

When these chromosomes are homologous, this just means that they have the same genes in the exact order. But, the actual sequences at some of the geni loci are a little different. They are different because they are alleles. 

Hope I could help!

Did the hospital make a mistake?

Yes, because the physical appearance of

the baby must have tall eyeballs.

No genotypes of the punnet square include a homo-zygous recessive trait.

Therefore the offspring must recieve a recessive allele from each parent to exhibit it so based on the data, it is impossible to have a baby with short eyes.
