If long fingers (L) are dominant over short fingers (l), what is the genotype for a homozygous dominant individual?

If dimples (D) are dominant over no dimples (d), what is the genotype for a homozygous recessive individual?

If purple flowers (P) are dominant over white flowers (p), what is the genotype for a heterozygous plant?

Assume big ears (B) are dominant over normal ears (b). You hypothetically cross a heterozygous male with large ears and a homozygous recessive female with normal ears. What is the chance you have an offspring with big ears?

Assume big ears (B) are dominant over normal ears (b). You hypothetically cross a heterozygous male with large ears and a homozygous recessive female with normal ears. What is the chance you have an offspring with small ears?

Assume yellow tails (Y) are dominant over brown tails (y) in an animal. You hypothetically cross a heterozygous male and heterozygous female. What is the chance you have a homozygous recessive offspring?

Assume yellow tails (Y) are dominant over brown tails (y) in an animal. You hypothetically cross a heterozygous male and heterozygous female. What is the chance you have a homozygous dominant offspring?
