Dominant character appears both in homozygous and heterozygous condition, whereas recessive character appears only in homozygous condition.
Dominant character appears both in homozygous and heterozygous condition, whereas recessive character appears only in homozygous condition.
The correct option is A True
The alternative forms of a factor (gene), leading to alternative forms of a character, are called alleles. When two haploid gametes containing exactly the same allele of a factor fuse during fertilization to form a zygote, the offspring that develops from that zygote is said to be homozygous; when the two haploid gametes
contain different alleles, the individual offspring is heterozygous. In heterozygous individuals, only one allele (the dominant one) is expressed, while the other (recessive) allele is present but unexpressed. Its expression is masked by the dominant alelle. For the expression of recessive character, two recessive alleles would be required.
