Punnett Square
Meiosis
True or False
Know the concepts
100
different forms of a gene (tall or short)
Alleles
100
is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
Punnett Square
100
Meiosis consists of what two cell division?
Meiosis 1 & 2
100
Alleles can have alternative versions. (Do not have to be the same)
False- Alleles can't have alternative versions. (They have to be the same)

How to complete a Punnett Square? (IN COMPLETE STEPS).
- Name the alleles involved.
- Check the parents' genotypes.
- Label the rows with one parent's genotype.
- Label the columns with the other parent's genotype.
- Have each box inherit letters from its row and column.
- Interpret the Punnett square.

Characteristics, category (seed color, flower position , height, seed texture.

What is Homozygous Dominant
WW
200
When do chromosomes line up in a single file?
Metaphase 2
200
There are 4 stages in Meiosis
False, there are 8
200
Explain the difference between Homozygous Dominant and Homozygous Recessive.
One has both capital letters and the other has both lower case letters
300
BOTH dominant traits can be seen in the phenotype.
Codominance
300
What is Homozygous Recessive?
hh
300
What is Telophase 1?
is the final stage in both meiosis and mitosis in a eukaryotic cell.
300
Punnett squares predict only some of the possible outcomes of a genetic cross between 2 parents.
False- ALL the possible outcomes.
300
How are traits passed down from parent to child?
Genes come in different varieties, called alleles. It contain two alleles for every gene, with one allele provided by each parent of an organism.
400
characteristics that are passed down from parent to offspring (height).
Gene

What is heterozygous?
Hh
400
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Meiosos
400
A gene can have a maximum two allele
False
400
The amount of different cells do you have at the end of Meiosis
4 generally different cells
500
Resulting phenotype is IN BETWEEN the original traits.
Incomplete Dominance
500
How many will be short?
Zero
500
What is Anaphase II?
cells split apart
500
During meiosis chromosome number reduction takes place in anaphase II.
False

Difference between Mitosis & Meiosis
Mitosis gives two nuclei, and hence two cells, while meiosis gives four. Mitosis gives identical cells to each other and to the mother cell
