Genetics (Mendelian & Non-Mendelian)

Front

What is Codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in a phenotype that shows both traits simultaneously, such as a calico cat with orange and black fur.

Front

What is the phenotype of a hamster with the genotype Ffbb?

Back

Speckled with tan fur.

Front

What is the genotype for Roan color in cattle?

Back

RW, which represents a mix of red (RR) and white (WW) coat colors.

Front

What is the phenotype ratio for yellow (D) and blue (d) organisms?

Back

3 yellow: 1 blue.

Front

What is the probability of an offspring having a dark beak and short wings if dark beaks (B) and long wings (L) are dominant traits?

Back

25%.

Front

Define Mendelian inheritance.

Back

A type of inheritance that follows the laws established by Gregor Mendel, involving dominant and recessive alleles.

Front

What is a dominant allele?

Back

An allele that expresses its trait even in the presence of a recessive allele.

Front

What is a recessive allele?

Back

An allele that only expresses its trait when two copies are present (homozygous).

Front

What is the principle of independent assortment?

Back

The principle stating that alleles for different traits are distributed to gametes independently of one another.

Front

What is incomplete dominance?

Back

A genetic situation where one allele does not completely dominate another, resulting in a blended phenotype.
