4. ### Mendelian Genetics Lab Question?

actually this quite easy.. ^,^ albino gene (a) is a recessive gene, so to be albino in fenotype, someone's gene should be homorecessive (aa) Normal pigmen genotype could be Aa or AA to be a taster, the genotype could be Tt (heterozygous) or TT (homozygous) to be...

7. ### biology-genotype question-help!!?

Since there was a 50% chance of getting a Taster, it means there was a 50% chance of nt gettn a taster so it was a 50:50 score so it happened randomly thus any could turn up. Just like flipping a coin

9. ### Why can't I taste anything? (Genetics lab taste test)?

Being able to taste any of those chemicals is a dominant trait, so if you can't taste them, it simply means you're homozygous recessive for all three traits. I hope that helps. Good luck!

10. ### There is a single gene that controls the ability to taste PTC paper..?

Both PP and Pp PP because both alleles are "tasters" Pp because one allele is "taster", which is dominant and so "masks" the recessive "non-taster" allele.
