Answer:
True.
Explanation:
The immunoglobulins, MHC ( major histocompatibity complex) and TCR (T cell receptor) plays an important role in the immune system. They protect the individual from the harmful antigens.
The evolution of immune system has done the duplication process. The genes gets duplicated and evolved to perform the specific function. The Immunoglobulin, TCR, and MHC gene evolve by the process of duplication. These genes mainly acts against the specific pathogen and shows the selection according to the primordial antigen receptors.
Thus, the answer is true.

Answer:
75%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (T) is dominant over the allele for white flowers (t).
According to the question, two heterozygous purple-flowered plants (Tt) are crossed i.e. Tt × Tt. The following gametes will be produced by each parent; T and t. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt, and tt.
Since purple allele (T) is dominant, offsprings TT, Tt, and Tt will be phenotypically purple-flowered. Hence, ¾ × 100 = 75% of offsprings will have purple flowers.
