Complete Dominance, Incomplete Dominance, Codominance

Front

What is Complete Dominance?

Back

A genetic scenario where one allele completely masks the effect of another allele in the phenotype.

Front

What is Incomplete Dominance?

Back

A genetic scenario where neither allele is completely dominant, resulting in a phenotype that is a blend of both alleles.

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.

Front

What is the genotype of a purebred black-finned whale?

Back

FF (homozygous dominant) for black fin color.

Front

What is the genotype of a white-finned whale?

Back

ff (homozygous recessive) for white fin color.

Front

In a cross between FF and ff, what is the probability of black-finned offspring?

Back

100% black-finned offspring.

Front

If a red flower (RR) is crossed with a white flower (rr), what is the phenotype of the offspring?

Back

All offspring will be red (Rr) due to complete dominance.

Front

In a cross between a red flower (RR) and a pink flower (Rr), what is the probability of pink offspring?

Back

50% pink offspring.

Front

What is the expected phenotype ratio in a monohybrid cross?

Back

1:2:1 genotype ratio and 3:1 phenotype ratio.

Front

What is the significance of Mendel's experiments?

Back

Mendel discovered the basic principles of heredity, including the laws of segregation and independent assortment.
