100

The unit that determines traits

What is a gene?

100

The man whom history credits as the founder of heredity, or, genetics

Who is Gregor Mendel?

100

An organism's complete genetic makeup. 

What is a genotype?

100

The physical appearance of an organism

What is a phenotype?

100

the observed physical description of the organism

What is phenotype?

200

A fertilized egg

What is a zygote?

200

The allele that is expressed in the offspring  

What is a dominant allele?

200

how likely something is to happen...expressed in numbers between 0 an 1, inclusive.

What is probability?

200

The allele that is not expressed in the offspring

What is a recessive allele?

200

Passing of genes from one generation to the next is called?

Heredity

300

The two letters representing the genotype of a plant heterozygous for tall

What is big T; little t? Tt

300
The grid where we determine each possible genetic outcome an offspring may have
What is a Punnett square
300

A genotype that contains two of the same allele

What is a homozygous genotype?

300

The information needed to fill in a Punnett square

What are the parents genotype?

300

A cell that contains a single set of chromosomes

What is haploid?

400

The probability of a heterozygous offspring when two heterozygous parents procreat.

What is 50%?

400

The two types of alleles possible

What is dominant and recessive?

400

In Mendel's pea plants, the first-generation hybrids expressed the dominant trait how often?

100% of the time

400

The genotypes of the parents if the offspring is tt

What is tt? (homozygous recessive)

400

When the phenotype is an intermediate version of the parents...a red flower crossed to a white flower produces a pink flower

What is incomplete dominance?

500

The letters representing homozygous recessive: HH, Hh, or hh

What is hh (little h/ little h)?

500

This genotype is represented by Hh.

What is heterozygous?

500

Crossing a homozygous dominant genotype with a homozygous recessive genotype always results in this genotype

What is heterozygous?

500

Gray eyes are a recessive trait. Cross a homozygous recessive mother and a heterozygous father. The odds of the child having gray eyes is

What is 50%?

500

The probability of a recessive phenotype when both parents are heterozygous  

What is 25%?
