Question

I was confused on how to obtain the ratios and solve these genetics problems.

I need to know how to do a mono, di, and tri hybrid cross. I know there is 2 ways but if you can pick the easiest/quickest way and explain it to me simply that would be great.

Answer 1

-phenotype means what we see from outside or physically. E.g. tall or small

-genotype means the genetic makeup like TT,Tt,tt.

-homozygous means the same allele like tt or TT.

-heterozygous means different allele like Tt.

-so in this way u can cross a mono,di,trihybrid

-i have tried to make u understand how to make gamates

-so simple method is just to make gamates and then cross by taking help of punnet square and once u have done so far then from there u can give answer to any question because the whole picture is in your front

-try by your own by taking examples of your own.

Try taking ration of phenotype and genotypes

Try taking ratio of heterozyous and homozygous progenies

Try the trihybrid corss i have left for u

- if u get any problem,fell free to ask the questions

NOTE- please rate if my efforts are aorth it and comment if u have any queries
