Answer:
C
Explanation: DNA is A-T-C-G, RNA is A-U-C-G
it is true that male genotype is XY and female genotype is XX but therefore a female does not contain a 44 number of gene(chromosome) each pair of a human "gene" have 23. in ym case it it false
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.
