Genetics - Non mendelian (Complex Patterns of Inheritance)

Match

Match

• Complete Dominance

• Incomplete Dominance

• Codominance

• Sex-linked (X-linked)

The dominant trait completely masks the recessive

Neither is dominant: The traits blend

The traits co-exist (at the same time; patterns); both are expressed

The trait is determined by its presence of the sex chromosome (X)

• The dominant trait completely masks the recessive

• Neither is dominant: The traits blend

• The traits co-exist (at the same time; patterns); both are expressed

• The trait is determined by its presence of the sex chromosome (X)

Match

• Sex-linked (X-linked) inheritance

Match

Hemophilia is a recessive x-linked disorder. Match each genotype and its phenotype

• X^HX^h

• X^hX^h

• X^HX^H

• X^hY

• X^HY

Female who is a carrier for hemophilia

Female who has hemophilia

Unaffected female (does not have hemophilia)

Male who has hemophilia

Unaffected male (does not have hemophilia)

• Female who is a carrier for hemophilia

• Female who has hemophilia

• Unaffected female (does not have hemophilia)

• Male who has hemophilia

• Unaffected male (does not have hemophilia)

Multiple Choice

Hemophilia is a sex-linked, recessive trait. A man who does not have hemophilia marries a woman who does not have hemophilia, but she got the gene from her dad . What is the probability of this couple having daughters that have hemophilia?

• 100%

• 25%

• 50%

• 0%

Multiple Choice

Hemophilia is a sex-linked gene. Males are more likely to be hemophilic than females because hemophilia is

• dominant in one sex and recessive in the other

• influenced by the hormones present in the individual

• the male has only one X-chromosome (the disease is carried only on the X-chromosome )

• the female does not have a Y-chromosome (the disease is carried only on the Y-chromosome )

Multiple Choice

Which of the following is an example of complete dominance in genetic traits?

• green pea + yellow pea= yellow peas

• red flower + white flower =pink flowers

• colorblindness inheritance

Multiple Choice

Which of the following is an example of incomplete dominance in genetic traits?

• green pea + yellow pea= yellow peas

• white cattle + red cattle -> roan cattle

• red flower + white flower =pink flowers

• colorblindness inheritance

Multiple Choice

Which of the following is an example of sex-linked inheritance in genetic traits?

• green pea + yellow pea= yellow peas

• white cattle + red cattle -> roan cattle

Incomplete dominance occurs in cats, which allows them to be Black, White, or gray as shown on this Punnett square. What percentage of the offspring will be black?

• 25

• 50

• 75

• 100

Multiple Choice

The image shows the pattern of inheritance for colorblindness.  From this diagram we can tell that colorblindness is

• a codominant trait

• a sex-linked trait

• carried on the Y chromosome

• is associated with a dominant allele

Multiple Choice

Males are more likely to suffer from a sex-linked disease or disorder because

• Males are the weaker sex

• Males have 1 X chromosome, so the disorder is more likely to be expressed

• Males have less DNA

Multiple Choice
