Answer: It is because it makes it more efficient to study organisms.
Explanation: Biologist classify organisms by considering similarities between them. The organisms which have closely related characteristics are placed in a separate domains by biologists. Domains are further divided into 6 Kingdoms. According to modern classification system, domain is largest unit of biological classification.
The offspring is unique and is not like its parent plant.
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
