Front

In guinea pigs, having fur is dominant (R) to being hairless (r). A guinea pig has RR genes and can only pass on an "R" gene to its children. The other parent will also have to give a gene (R or r). What trait could the children have?

Back

All must have fur.

Answer explanation

This guinea pig gave it's kids all an "R" so it doesn't matter what the other parent gives... they'll have the dominant furry trait.

Front

A guinea pig inherits the recessive gene from both parents. It's phenotype is:

Back

hairless

Front

In guinea pigs, having fur is dominant (R) to being hairless (r). A guinea pig has rr genes and can only pass on an "r" gene to its children. The other parent will also have to give a gene (R or r). What trait could the children have?

Back

They could have fur or be hairless, depending on the other parent.

Answer explanation

This guinea pig gave its kids all an "r". If the kids get an R from the other parent, they will have fur.. But an "r" from the other parent will result in being hairless
