Question

question 1
match each mode of inheritance to a statement listed below.
the frizzle gene in chickens affects many traits, including feather type, metabolic rate, blood flow rates, and digestion.
a parent with curly hair and a parent with straight hair produce a child with wavy hair.
the color of wheat kernels is controlled by the interaction of two separate genes with one gene affecting the expression of the other gene.
a humans ability to roll their tongue is dependent on a single gene that is either dominant or recessive.

Explanation:

1. The frizzle gene in chickens affecting multiple traits is pleiotropy as one gene influences multiple phenotypic traits.
2. A parent with curly hair and one with straight hair producing a child with wavy hair is incomplete - dominance where the heterozygous phenotype is intermediate between the two homozygous phenotypes.
3. The color of wheat kernels controlled by the interaction of two separate genes with one affecting the expression of the other is epistasis.
4. A human's ability to roll their tongue dependent on a single gene that is either dominant or recessive is a Mendelian trait.

Answer:

1. pleiotropy
2. incomplete dominance
3. epistasis
4. Mendelian trait
