Final Answer:
1. AA — Homozygous Dominant
Bb — Heterogeneous
Nn — Heterogeneous
DD — Homozygous Dominant
Rr — Heterogeneous
Ee — Heterogeneous
ff — Homozygous Recessive
CC — Homozygous Dominant
Pp — Heterogeneous
TT — Homozygous Dominant
Mm — Heterogeneous
Jj — Heterogeneous
kk — Homozygous Recessive
Gg — Heterogeneous

2. Purple flowers: PP — Purple, Pp — Purple, pp — White
Brown eyes: BB — Brown, Bb — Brown, bb — Blue
Round seeds: RR — Round, Rr — Round, rr — Wrinkled
Tall plants: TT — Tall, Tt — Tall, tt — Short
3. Right-handed (homozygous): RR
Right-handed (heterozygous): Rr
Left-handed: rr
Free earlobes (homozygous): FF
Free earlobes (heterozygous): Ff
Attached: ff
4. RR × rr → all offspring Rr → 100% round
Rr × rr → 2/4 = 50% round (Rr), 50% wrinkled (rr) → 50% round
