Complete Dominance Monohybrid Crosses

Front

What is a homozygous recessive allele?

Back

A homozygous recessive allele consists of two identical recessive alleles, represented as 'tt' in genetics.

Front

What is the difference between phenotype and genotype?

Back

Phenotype refers to the observable traits of an organism, while genotype refers to the genetic makeup or alleles present.

Front

What does the term 'complete dominance' mean in genetics?

Back

Complete dominance occurs when the dominant allele completely masks the effect of the recessive allele in a heterozygous genotype.

Front

Who is known as the father of genetics?

Back

Gregor Mendel is known as the father of genetics for his work on inheritance patterns in pea plants.

Front

What is a Punnett square used for?

Back

A Punnett square is a diagram used to predict the genetic outcomes of a cross between two organisms.

Front

What is the genotype of an organism with brown eyes if brown is dominant over blue?

Back

The genotype could be either BB (homozygous dominant) or Bb (heterozygous).

Front

If T = tall and t = short, what is the phenotype of a Tt plant?

Back

The phenotype of a Tt plant is tall, as the dominant allele T masks the effect of the recessive allele t.

Front

What trait is inherited from parents in dogs?

Back

The color of a dog's fur is an inherited trait from its parents.

Front

What does it mean if two organisms have the same phenotype but different genotypes?

Back

It means they exhibit the same observable traits but have different genetic compositions.

Front

What is the significance of Gregor Mendel's experiments?

Back

Mendel's experiments established the basic principles of heredity, including the laws of segregation and independent assortment.
