Complex Inheritance Patterns Flashcard

Front

What is hemophilia?

Back

A genetic disorder that impairs the body's ability to make blood clots, leading to excessive bleeding.

Front

Which of Queen Victoria's children had hemophilia?

Back

Leopold.

Front

What is incomplete dominance?

Back

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

Front

Provide an example of incomplete dominance.

Back

Red and white flowers producing pink flowers.

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is an example of codominance?

Back

A flower with both red and white stripes.

Front

What is the probability of two heterozygous type A blood parents having a type O blood child?

Back

25%.

Front

What is the term for traits controlled by multiple genes?

Back

Polygenic inheritance.

Front

What is the difference between dominance and codominance?

Back

In dominance, one allele masks the effect of another; in codominance, both alleles are expressed equally.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.
