• male

• female

• red-eyed

• mentally challenged

Hemophilia is a sex-linked recessive gene. If a carrier mother married to a hemophiliac husband, their genotypes are

• X^HX^H and X^HY

• X^HX^h and X^hY^h

• X^hX^h and X^HY

• X^HX^h and X^hY

Red flower cross with a blue flower would produce a purple flower. What pattern of inheritance displayed in the purple flower?

• codominance traits

• incomplete dominance traits

• multiple alleles of flower height

• Mendel's principle of dominant traits

Usually recessive genes/traits that are carried and passed on through either on x or on y chromosomes.

• dominant traits/genes

• intermediate traits/genes

• sex-linked traits/genes

• autosomal inheritance

A section of chromosomes that codes for a trait can be called a(n):

• gene

• nucleus

• base-pair

• nucleotide

In a pedigree, how an individual with sex-linked traits/disorders are represented?

• capital and lower case letters of the alphabet

• clear circle: unaffected male

  clear square: unaffected female

• shaded circle: affected female

  shaded square: affected male

• shaded circle: affected male

  shaded square: affected female

Most sex-linked disorders, such as hemophilia, are carried on the X chromosomes because

• X chromosome is larger than Y chromosomes

• X chromosome is shorter than Y chromosomes

• X chromosome has more genes than Y

• X chromosome has less genes than Y
