Intro to Mendelian Genetics

What is a F1 Generation?

hybrid offspring produced from crossing 2 breeding plants

sexual reproduction

When plants reproduce by self pollinniation on ________ with another true breeding plant, the offspring will have the same trail.

How is F2 Generation produced?

2 individuals of the F1 generation creates a new generation with mixed traits

What is F2 Generation a result of?

monohybrid cross

What is the dominant factor?

factor that is expressed in all F1 generation

What is the dominant factor?

factor that remained but was hidden in the F1 generation

What is an Allele?

alternate versions of genes

what is homzygous

if both alleles are identical

what is heterozygous

if 2 alleles are different

what are dominant alleses represented as?

dominant alleles are represented with uppercase letter

What are recessive alleles represented as?

Recessive alesis are represented with lowercase letters

What does the law of segregation state?

1. each organism carries 2 factors 2 genes one from each parent
2. parent organisms donate only 1 copy of each gene to their gametes

What is a phenotype?

trait of an individual that is expressed

What is a genotype?

genes that an individual has

What is a monohybrid cross?

when only 1 trait is being investigated

What is discontinuous variation?

When characteristics do not interact with each other

What is continous variation?

Traits that affected by genes around it that may have an additive or negative effect on its gene

What is a dihybrid cross

this is when looking at the inheritance of 2 pairs of alleles

How many possible gametes can an individual who is heterozygous for 2 characterics produce

4

What is law of independent assortment? (2)

1.Inheriting one allele has no impact on the inheritance of another
2.so parents heterozygous for 2 different alleles are just as likely to produce any of the 4 gametes
