Answer: Option [A]The correct answer is Recessive. Genes come in different versions, or alleles, with dominant alleles being expressed over recessive alleles. Recessive alleles are only expressed when no dominant allele is present. In most sexually reproducing organisms, each individual has two alleles for each gene (one from each parent).
Answer: Option [A]A pair of contrasting character is termed as Allelomorphs. Allelomorphs is the another name of the allele . Allele are a pair of alternative form of gene. Single trait is control by each allele. Allele represent the contrasting character.

Answer: Option [C]The correct answer is Ovum. In animals, during the process of sexual reproduction special cells having one half the chromosome number (gametes) are produced as a result of meiosis. The male gamete is called sperm, while the female gamete is called ovum. The haploid gametes (sperm and ovum) fuse to form a diploid zygote, which develops to form embryo.
Answer: Option [B]The character which appears physically in an animal is Phenotype. The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior.
Answer: Option [D]The frequency of a character is found to be increasing when it is inheritable. A single attribute of an animal or plant transmitted at one locus from generation to generation in accordance with genetic principles is called inheritable character. Since, it is inherited from one generation to other its frequency keeps on increasing.
