Mendelian and Non-Mendelian Genetics

Mendelian traits are traits that are passed down by ​ (a)   alleles of ​ (b)   .

• dominant and recessive
• one gene
• multiple alleles
• Non-Mendelian Traits

​ Non-Mendelian traits are traits that ​ (a)   dominance or recessive alleles from a gene. ​ (b)    is a general term that refers to any pattern of inheritance in which traits ​ (c)   in accordance with Mendel’s laws.

• don't have complete
• have complete
• Non-Mendelian inheritance
• do not segregate

Green pod color (G) is dominant over yellow pod color (g) in pea plants. Determine the genotypes of the offsprings from crossing homozygous dominant (GG) and heterozygous (Gg) parents.

• GG, GG, Gg, Gg

• Gg, Gg, Gg, gg

• GG, GG, GG, GG

• gg, gg, gg, gg

Green pod color (G) is dominant over yellow pod color (g) in pea plants. Determine the phenotypic ratio of the offsprings from crossing homozygous dominant (GG) and heterozygous (Gg) parents.

• 50% green pod and 50% yellow pod

• 100% green pod

• 100% yellow pod

When pure breeding red cows (RR) are bred with pure breeding white cows (WW), the offsprings are roan (a pinkish coat color) (RW). Based on the phenotype of the offsprings produced, is this Mendelian or Non-mendelian?

• Mendelian

• Non-mendelian

• Both Mendelian and Non-mendelian

• Cannot be determined

Co-dominance and Incomplete dominance are two types of ​ (a)   . ​ (b)   essentially means that no allele can block or mask the expression of the other allele. On the other hand, ​ (c)   is a condition in which a dominant allele does not completely mask the effects of a recessive allele.

• genetic inheritance
• Co-dominance
• incomplete dominance
• Mendelian trait
