Biology Unit 11: Genetics
What does and doesn't a punnet square show? - correct answer-Does:
-all possible results of a genetic cross
-the alleles in the gametes of the parents
-the genotyoes of the offspring
Doesn't:
-the actual results of every genetic cross
Dominance - correct answer-Situations in which one allele for a gene is completely dominant
over another allele for that gene
If neither one of the parents show the trait and yet the child does, that means the trait is... -
correct answer-Recessive
dominant trait - correct answer-the apparent or visible trait
the trait that is visible in a ____________ pair is the ________ trait - correct
answer-heterozygous, dominant
Who was Gregor Mendell - correct answer-an austrian monk who is known as the father of
genetics
cross-pollination - correct answer-the process of cutting away the male parts of a flower and
dusting the female parts with pollen from a different flower
Hybrid - correct answer-the offspring of crosses between parents of different traits
What does P1 stand for - correct answer-Parent generation
What does F1 stand for - correct answer-first fillial (daughter/son) generation
gamete - correct answer-human sex cell
homozygous - correct answer-having two identical alleles for a particular gene (TT)
heterozygous - correct answer-having two different alleles for the same gene (Tt)
phenotype - correct answer-physical characteristics of an organism
genotype - correct answer-genetic makeup of an organism
co-dominance - correct answer-a condition in which both alleles of the gene are expressed.
eg. when a chicken is heterozygous, it is black and white speckled
