Question

The set of dominant characters are

• A. Shrunken endosperm of maize and coloured coat of rabbit
• B. Starchy seeds of maize and long stature of man
• C. Albino colour and horned character of cattle
• D. All of the above

Answer 1

The correct option is A Shrunken endosperm of maize and coloured coat of rabbit

In a heterozygote, one allele, the dominant, may cover up or hide the expression of the other allele, the recessive. Genes are often named by a letter that stands for the dominant trait. The dominant allele is capitalized and the recessive is in lower case. In maize, the shrunken endosperm of maize is a dominant character, the allele for coloured grain is (dominant) to the colourless one; the rounded grain is dominant, R to the wrinkled one, r. In the case of rabbits, four alleles exist for the c gene. The wild-type version, C+C+, is expressed as brown fur. The Chinchilla phenotype, cchcch, is expressed as black-tipped white fur. The Himalayan phenotype, chch, has black fur on the extremities and white fur elsewhere. Finally, the albino, or "colorless" phenotype, cc, is expressed as white fur.
