What is Non-Mendelian Genetics?

Back

Non-Mendelian Genetics refers to patterns of inheritance that do not follow Mendel's laws of inheritance, including incomplete dominance, codominance, and multiple alleles.

Front

What is Codominance?

Back

Codominance is a type of inheritance where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is Incomplete Dominance?

Back

Incomplete Dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two.

What is the genotype for a female carrier of hemophilia?

Back

X^H X^h (where X^H is the normal allele and X^h is the hemophilia allele).

Front

What are the possible blood types of children from a man with blood type AB and a woman with blood type O?

Back

The possible blood types are A and B.

Front

What is the probability of offspring having type O blood if both parents are heterozygous for type A blood?

Back

The probability is 25%.

Front

What is the probability of having a brown-furred puppy from two heterozygous black dogs (B/b)?

Back

The probability is 25%.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present (homozygous).

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present (heterozygous).

Front

What does X-linked inheritance mean?

Back

X-linked inheritance refers to genes located on the X chromosome, where males (XY) are more likely to express recessive traits than females (XX).
