Why do all offspring have the same fur color?

They have the same alleles for the relevant genes

Why do all offspring have brown fur? a. Because the alleles for black fur color is dominant b. They genes were not mixed well enough c. Because the allele for brown fur color is dominant d. Because the allele for brown fur color is recessive

no

Pedigree interactive

What does it mean when a trait is independent for another trait?

The inheritance of a trait does not affect the inheritance of another trait

yes

Punnett Square interactive

Knowing that Joseph is color blind, what is his genotype? Have a look at the Punnett square below and figure out which genotype inherited from Shannon and dad causes color blindness.

XcY

If Joseph has children with someone who doesn't carry the gene for color blindness, will their children be color blind?

No, none of them will be colorblind
