Alternate Patterns of Inheritance

Different types of _______ inheritance patterns include incomplete dominance, co-dominance, multiple alleles, polygenic, and sex-linked.

• Non-Mendelian

• Mendelian

The alleles of a gene pair in a heterozygote are both expressed with no blending.

• codominance

• incomplete dominance

• polygenic

• multiple alleles

NGSS.HS-LS3-1

Which statement is true about X-linked genes?

• The male needs two copies of the gene but will express the trait regardless of whether the alleles are dominant or recessive.

• The male needs two copies of the gene but will express the trait only if both alleles are dominant.

• The male needs only one copy of the gene and will express the trait regardless of whether the allele is dominant or recessive.

• The male needs only one copy of the gene but will express the trait only if the allele is dominant.

Neither allele is dominant. Heterozygote has a blended phenotype.

• incomplete dominance

• codominance

• multiple alleles

• sex linked

Trait determined by more than one gene, sometimes hundreds of genes.

• polygenic

• multiple alleles

• codominant

• sex linked

Polygenic inheritance is very common in determining characteristics that are

• Qualitative in nature.

• Quantitative in nature.

• Primarily hidden.

• simple Mendelian traits
