This is a variation of a particular characeristic

What is a trait?

100

what is cross fertilization?

using sperm from one plant and joining it with the egg from another plant

100
What is a heterozygous character?
Have different alleles for the character
100
What do you call an observable trait (example: eye color)
phenotype
100
what do you call an organism with the dominant phenotype?
herozygous OR homozygous dominant
200
This is the study of heridity
What is Genetics?
200

What are hybrids?

The offspring of two true-breeding plants

200
What is the dominant allele?
The allele that effects the trait
200
What is a testcross?
Breeds an indvidual with the dominant phenotype with a homozygous recessive individual to determine the dominate individual's genotype
200
what is a genotype
the genetic makeup of an individual
300

One of the first scientists to investigate inheritance patterns

Gregory Mendel

300
what is a monohybrid cross?
Crosses between plants with one characteristic different
300

What is a recessive allele?

The allele that does not seem to effect the trait

300
What is a dihybrid cross?
crosses of individuals with two different characteristics
300
what is the word for alternative forms of genes?
alleles
400
What does Gregory Mendel's hypothesis of inheritance say?
Parents give their offspring separate and distinct factors that are responsible for inherited traits
400
What is an allele?
different forms of genes
400

What is the principle of segregation?

Each gamete carries one allele for each trait.

400

What is the principle of independent assortment?

the alleles for different genes are sorted into gametes independently

400
what is a phenotype?
an observable trait
500
What did Mendel use in his inheritance experiments?
true-breeding pea plants
500
What is a homozygous individual?
Has two of the same allele
500
What is the genetic makeup of an individual called?
genotype
500
What would you call an organism that shows the recessive phenotype?
homozygous recessive
500

what do you call a diagram that shows the different possible combinations of alleles and the probability that each combination will occur?

Punnet Square
