UNIT 3: INSTRUCTIONAL SEQUENCE 1 FLASHCARD

Front

What is a dihybrid cross?

Back

A genetic cross that involves two traits, each represented by two alleles.

Front

What is the probability of obtaining a specific phenotype in a dihybrid cross?

Back

The probability can be calculated using a Punnett square, considering the ratios of the traits.

Front

What is the phenotype of an organism?

Back

The observable physical characteristics of an organism, determined by its genotype.

Front

What is the genotype for a homozygous dominant organism?

Back

An organism with two identical dominant alleles for a trait, represented as 'AA'.

Front

What is the genotype for a homozygous recessive organism?

Back

An organism with two identical recessive alleles for a trait, represented as 'aa'.

Front

What is a heterozygous genotype?

Back

An organism with two different alleles for a trait, represented as 'Aa'.

Front

Who is known as the father of genetics?

Back

Gregor Mendel, who conducted foundational experiments on inheritance.

Front

What is complete dominance?

Back

A form of inheritance where one allele completely masks the effect of another allele.

Front

What is codominance?

Back

A form of inheritance where both alleles in a heterozygote are fully expressed.

Front

What are multiple alleles?

Back

A situation where a gene has more than two alleles, such as the ABO blood type system.
