100

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
