Question

1. When will a recessive trait show its effect?
a. Even if no recessive genes for that trait are
present
b. In the presence of one recessive gene
c. When two recessive genes for a trait are present
d. Only if the mother has the recessive gene

Answer 1

Answer:

Option c

Explanation:

A recessive trait will only appear if the if two recessive alleles for a trait are present. if present coupled with a dominant allele, its effect will be masked by the dominant allele. Although for an X linked condition that shows the recessive pattern of inheritance. In the males, they only need to have just one copy of that particular recessive allele.

Answer 2

Answer: Option C.

When two receive genes for a trait are presence.

Explanation:

Recessive allele or genes is the gene that is not expressed in a trait when there a dorminant gene. It's effect is always masked by dorminant gene .

A recessive trait can be expressed phenotypically if a person inherit

homozygous recessive allele.

For example the recessive allele for dwarf is t. If a person inherit two receive allele for dwarf need (tt), the dwarf trait will be expressed phenotypically.
