2
___: ____
Another name for homozygous
purebred
What is an allele
Type of gene
When determining the parent gametes in a dihybrid, which of Mendel’s laws applies?
Law of independent assortment
(alleles for different traits sort independently of one another into separate gametes)
What are gametes
Sex cells
What is fertilization
Male and female reproductive cells joining
genetic makeup of an organism
genotype
Another name for heterozygous
Hybrid
Father of genetics
Gregor Mendel
What are hybrids
heterozygotes
What is a phenotype
Physical attributes
Formula for percent deviaiton?
(Sum of the differences between expected and observed)
____________________________________________
totall # of occurances
then multiple by 100 to get a %
Formula for probability
1 / total number of occurance
Physical apperance due to the expression of a genotype
Phenotype
Type of cross involving the crossing of one trait at a time
monohybrid
How many alleles are found in a parent genotype in a dihybrid cross?
4
What is the formula for the phenotypic ratio for a monohybrid cross?
Most dominant phenotype: Most recessive
Number of gametes from each parent during a monohybrid
2
What are different ways that probabiltiy can be expressed?
- decimal
- fraction
- %
- ratio
What is genetic segregation
Separation of alleles
