Gregor Mendel's work

[blank_start]Heredity[blank_end] is the passing of physical characteristics from parents to offspring.

Which of the following are examples of traits?

[blank_start]Genetics[blank_end] is the scientific study of [blank_start]heredity[blank_end], which is the passing of traits from parents to offspring.

What is the process that forms a new organism through the joining of sperm and egg?

A [blank_start]purebred[blank_end] organism is the offspring of many generations that have the same trait.

What do you call the first generation of offspring?

In all of Mendel's crosses, only [blank_start]one[blank_end] form of the trait appeared in the F1 generation. However, in the F2 generation, the "lost" form of the trait always reappeared in about [blank_start]1/4[blank_end] of the plants.

What word do scientists use for the factors that control a trait?

What are the different forms of a gene?

Which allele is always hidden whenever the dominant allele is present?

What is an organism that has both the dominant and recessive allele present for a trait?

Which letters represent the alleles for an organism that is hybrid for the tall trait?

If an offspring inherits a dominant allele from the mother and a recessive allele from the father, which letters will represent that gene?

If an offspring inherits a tall allele from one parent and a short allele from the other, the offspring will be....

Mendel was widely recognized for his contributions to genetics while he was alive.
