In some pine trees, long needles are dominant over short needles. which of the following statements is true?

1.) a pine tree with long needles must be homozygous dominant

2.) a pine needle with short needles must be heterozygous recessive

3.) a hybrid pine tree will have the same phenotype as a homozygous dominant pine tree

4.) a hybrid pine tree will have the same genotype as a homozygous recessive pine tree

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
