Question

If heterozygous parents are crossed, which of the following trait/s will have more frequency in the F1 generation?

• A. recessive character
• B. dominant character
• C. co-dominant character
• D. Polygenic character

Answer 1

The correct option is B

dominant character

The trait that will appear in F1 generation depends on the genotype of the parents being crossed. If heterozygous parents are being crossed, there is a possibility of having both, dominant and recessive, traits appearing in F1 generation. Each heterozygous parent will produce two types of gametes, one with dominant and one with a recessive allele. When these gametes fuse, they give rise to all three combinations. But dominant allele will have more frequency i.e. 3/4 of the offsprings will show the dominant character.
