- Q1Dominant TraitIf this trait is passed down, it always appear in the offspring (Capital Letters)30sBIOL.6f
- Q2Recessive TraitThese traits only appear if both alleles are for the recessive trait (Lowercase Letters)30sBIOL.6f
- Q3HomozygousHomozygous means that both alleles are the same.(GG, bb, RR, rr, IAIA)30sBIOL.6f
- Q4HeterozygousHeterozygoys means that the alleles are different.(Gg, Bb, Rr, IAIB)30sBIOL.6f
- Q5What percentage is each box worth in a Punnett square?Each box is 25%30sBIOL.6f
- Q6How do you calculate the total percentages or combinations in a dihybrid cross?You multiply the number from each small Punnett Square30sBIOL.6f
- Q7AlleleThey are the different versions of a gene. (Example: White fur and gray fur are different alleles for fur color.)30sBIOL.6f
- Q8GeneThey are sections of DNA used to make proteins.30sBIOL.6f
- Q9GenotypeThe combination of genes in an organism30sBIOL.6f
- Q10PhenotypeThe physical appearance of the organism30sBIOL.6f
- Q11Simple Dominanceone allele is completely dominant and the other is recessive. (This is what you learn first.)30sBIOL.6f
- Q12Incomplete DominanceA heterozygous organism has an intermediate phenotype (Example:red x white→pink)30sBIOL.6f
- Q13CodominanceA heterozygous organism has a phenotype that is a combination of both traits (Example: white x black → spotted)30sBIOL.6f
- Q14Sex-Linked RecessiveSex linked traits appear on the X chromosome. Males are more likely to receive a sex-linked recessive trait30sBIOL.6f
- Q15What does it mean for a gene to be expressed?Genes are expressed when they are activated and used to make a protein30sBIOL.6f
