Example: Apples Sold. Here is a pictograph of how many apples were sold at the local shop over 4 months: Note that each picture of an apple means 10 apples (and the half-apple picture means 5 apples).So the pictograph is showing: 1  In January 10 apples were sold.ere is a pictograph of how many apples were sold at the local shop over 4 months: Note that each picture of an apple means 10 apples (and the half-apple picture means 5 apples).

However, for males, there only needs to be one copy of an X-linked recessive gene in order for the trait or disorder to be expressed. For example, a woman can carry a recessive gene on one of the X chromosomes unknowingly, and pass it on to a son, who will express the trait:Therefore, half of the daughters have the gene and can pass it to the next generation.The other half do not have the gene and, therefore, cannot pass it on.owever, for males, there only needs to be one copy of an X-linked recessive gene in order for the trait or disorder to be expressed.

Another way to define a recessive trait is one that is never expressed by the heterozygous genotype. For example, the heterozygous genotype for earlobe type (Ee) produces detached earlobes because the dominant allele (E) hides the effects of the recessive allele (e).ecessive traits are those that are expressed or seen only when a homozygous recessive genotype is present. Homozygous recessive just means having two of the same recessive alleles. Remember, recessive alleles are masked by dominant alleles.
