Question

what would be the sum of phenotypes and genotypes obtained from a trihybrid test cross ?​

Answer 1

Answer:

hey mate...

. During a dihybrid cross,

The phenotypic ratio is 9:3:3:1.so,there are a total of 4 phenotypes produced.

.The genotype ratio is1:2:1:2:4:2:1:2:1.so,there are a total of 9 genotypes produced.

so total number of phenotypes and genotypes are 4+9=13.

thanks...✌️✌️✌️

Answer 2

The sum of phenotypes and genotypes obtained from a trihybrid test cross:

• As a "dihybrid cross", the phenotypic ratio is 9:3:3:1.
• So, there are a total of 4 phenotypes produced.
• Therefore, the total number of phenotypes and genotypes produced in a "dihybrid cross" are 4 + 9 = 13.
• The phenotype ratio concluded for dihybrid cross is "9:3:3:1".
• Of the 16 possible allele combinations: Nine combinations yield offspring with both dominant phenotypes.
• Three combinations each generate offspring with one dominant and one recessive phenotype.
