Condoms are the only type of birth control that protects against STDs. When used correctly, condoms are also fairly effective at protecting against pregnancy — but they're not as successful as hormonal methods like the Pill, patch, ring, IUD, or birth control shot.
1. Allele.
2. Dominant / It has a uppercase letter
3. Genotype/ the different combinations of alleles
4. Recessive/in this case there is only a lowercase letter so it is recessive
Do you have any examples?
That would help a lot! :)
