Question

Heterozygous Alleles are said to be silent carriers of a trait. What does this mean?

If two heterozygous parents each pass on a recessive allele their offspring will show a recessive
phenotype
O A Heterozygous individual will always show the recessive trait
O They carry both homozygous dominant and homozygous recessive Alleles
The alleles will influence other genes.

Answer 1

Heterozygous alleles are called silent carriers of a trait because they carry two different alleles for a particular gene, but only one allele is expressed in the phenotype, while the other remains "silent." The expressed allele is usually dominant, while the silent allele is usually recessive. This means that the individual carrying the heterozygous allele will not show the recessive trait, but they can still pass it on to their offspring.

If two heterozygous parents each pass on a recessive allele, their offspring has a 25% chance of inheriting two recessive alleles and showing a recessive phenotype. In this case, the heterozygous parents are carriers of the recessive trait, but do not show it in their phenotype.

Therefore, the correct answer is: If two heterozygous parents each pass on a recessive allele their offspring will show a recessive phenotype.
