Suppose the two possible alleles for the height gene are tall and short. If short is recessive to tall, provide the symbol repre
navik [9.2K]

Phenotype - short , Tall

Genotype - tt (short) , TT or Tt (tall)

<u>Explanation:</u>

In Mendelian Genetics, <em>Dominant traits</em> are represented by capital letters and <em>Recessive traits</em> are represented by small letters.

So if height is the character considered, then the traits would be short and tall.

Tall is the dominant phenotype and short is the recessive phenotype.

The alleles of the gene for height are T and t.

The genotype for Tall trait is TT or Tt.

The genotype for short trait is tt.

Therefore, the symbol representation of phenotype (Tall) is TT or Tt and for phenotype (short) is tt.

Compare and contrast the techniques of microscale and miniscale distillation in terms of efficiency of distillation. what are ad
Kitty [74]
Distillation is a process of separation of two liquids on the basis of their difference in the boiling points. There are two types of distillation process- Microscale distillation and miniscale distillation depending on the type of apparatus used for distillation.
In case of microscale distillation, microscale apparatus is used when the volume of liquid to be distilled is less than 5 ml. Whereas, in case of miniscale distillation, miniscale apparatus is used when the volume of liquid is more than  5 ml.
Hickman distilled head is used for microscale distillation whereas a bit larger vessels are used in miniscale distillation.
Micorscale and miniscale techniques have their own advantages. Both these techniques are cost effective, use less equipments and environmental friendly. Miniscale distillation is used yields more product which is easy to measure. Microscale distillation are difficult but it avoids large cumbersome distillation process and instruments.
