What is a dominant allele?

Back

A dominant allele is an allele that masks the effect of a recessive allele when both are present in an organism.

Front

What is a recessive allele?

Back

A recessive allele is an allele that is masked by the presence of a dominant allele and only expresses its trait when two copies are present.

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 do chromosomes contain?

Back

Chromosomes contain DNA, which carries genetic information.

Front

How is a dominant allele represented in genetic notation?

Back

A dominant allele is represented by a capital letter.

Front

How is a recessive allele represented in genetic notation?

Back

A recessive allele is represented by a lowercase letter.

Front

What is the process of pollination?

Back

Pollination is the process by which male and female sex cells (gametes) are transferred in flowering plants for reproduction.

Front

What is fertilization in the context of genetics?

Back

Fertilization is the process where the male and female gametes unite to form a zygote.

Front

What is the role of DNA in genetics?

Back

DNA contains the instructions for the development, functioning, growth, and reproduction of all known living organisms.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, representing the alleles it possesses.
