Incomplete and Codominance

Front

What is incomplete dominance?

Back

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 traits.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that shows both traits equally.

What is the genotype for blood type O?

Front

If a black chicken (BB) is crossed with a black and white chicken (BW), what is the probability of getting a black and white chicken?

Back

50%.

Front

What is the phenotype of a heterozygous radish that is red (RR) crossed with a white radish (WW)?

Back

Purple (RW) due to incomplete dominance.

Front

In a cross between a red radish and a white radish, what are the expected offspring phenotypes?

Back

All purple radishes.

Front

What does the term 'allele' mean?

Back

Different forms of a gene that can exist at a specific locus on a chromosome.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits.

Front

What is the expected phenotypic ratio in a monohybrid cross?

Back

3:1 ratio of dominant to recessive traits.

Front

What is the significance of the Punnett square in genetics?

Back

It is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.
