The father of modern genetics.
Who is Gregor Mendel?
100

A process of cell division that reduces the number of chromosomes by half through 2 rounds of cell division resulting in 4 haploid cells.

What is Meiosis?

100
In pea plants T=tall and t=short. If I breed a homozygous tall plant with a homozygous short plant, what is the probability that their offspring will be short?
What is 0%.
100
traits that are passed from parents to offspring.
What is heredity?
100
An allele whose trait always shows up in the organism when the allele is present.
What is a dominant allele?
200

Mendel's original occupation before he started studying genetics.

What is a Monk

200

During this stage, "crossing over" occurs. This allows genetic information to be exchanged.

What is Prophase I?

200

Why is a hybrid pea plant stem height tall?

The dominant allele for tall stems mask the recessive allele for short stems

200
An organisms physical appearance or traits.
What is phenotype?
200
An allele that is covered up when the dominant allele is with it.
What is a recessive allele?
300

What country did Mendel hail from?

What is Austria?

300

In Meiosis II, the second division, the chromatids pull away in which cell phase?

What is anaphase II?

300

What will be the result if I cross two heterozygous pairs of alleles? Provide the ratios

1:2:1

300
An organism's set of alleles that determines the expression of a particular characteristic or trait.
What is genotype?
300

Has two mostly identical alleles, same length, same centromere placement. Just different descriptions of same trait.

What is homozygous?

400

The results Mendel got when he bred his F1 generation plants

What is 3 tall and 1 short plant?

400

In meiosis, in telophase I, after cytokinesis the results are how many cells?

What is 2?
400

Do the Punnett Square, Bb and bb B = Black Dominant bb = White Recessive One rabbit is heterozygous while the other is homozygous recessive The ratio of white to black offspring is______

What is 2:2

400
The different forms of a gene.
What are alleles?
400
Has two different alleles.
What is heterozygous?
500

Name 2 reasons why Mendel chose garden pea plants as his control subject?

-They reproduce sexually

-Pea plants usually self pollinate, so he could control the pollination through cross pollination

-He could study one trait at a time

500

____________ are reproductive cells. Examples egg and sperm cells that have 23 chromosomes. The results of meiosis.

What are gametes?

500

What will be the phenotype trait result of incomplete dominance for crossing a pure bred red snapdragon and a pure bred white snapdragon?

 What is pink?

500

A cell with a full set of genetic material, consisting of paired chromosomes. (one set from each parent)

What is a diploid cell?

500

The occurrence of one or more extra sets of all chromosomes in an organism and give an example.
