What does a Punnett Square show?

The probability of each genetic mix

When traits that were hidden in F1 reappeared in F2, Mendel realized

that genes stay segregated and can be present but hidden

What happened in Mendel's F2 generation?

The recessive allele showed up again

Alleles are the result of

mutations duplicating genes during meiosis

The letters on the outside of a Punnet square represent

the possible alleles in sperm or egg cells

What happens to the "losing" allele?

It stays apart and can be passed on to future generations.

suppressed unless two copies are present

combination of genes/alleles for a given trait

Are these definitely all PUREBRED red roses?

No, some might be heterozygous (like Rr)

A phenotype is........

the physical observable expression of a gene combination
