genetics Flashcards
what is genotype (all-flash cards using the BB Bb bb )
the genetic makeup of an organism; BB Bb bb
what is phenotype
the trait so for example the color… BB Bb bb, this would mean the color would be brown
what is a dominant
mask a recessive
what is recessive
2 alleles eg, bb
what is homozygous
same alleles eg, BB bb
what is heterozygous
different alleles eg, Bb
what is homozygous dominant
Homozygous means that the organism has two copies of the same allele for a gene.
it would be BB brown eyes because they are the same
what is heterozygous dominant
The term “heterozygous” also refers to a pair of alleles. it would be Bb because they are different but the big b is dominant
what is homozygous recessive
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype.
it would be bb because they are the same and they are recessive
