Assuming a typical monohybrid cross in which one allele is completely dominant to the other, what phenotypic ratio is expected i

f the F1's are crossed?
Biology
1 answer:
IgorC [24]3 years ago
8 0

Answer:

Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1

This shows the dominance of allele A.

However if two of  the F1 generation are crossed then:

The  F2 is AA,Aa,Aa,aa the phenotypic ratio is

                        3   ;     1

W<u>hile the Genotypic ratio is ratio;</u>

<u>   1AA : 2Aa Aa; 1aa(1 ;2;1)</u>

If present, the ________________ allele will always be expressed as the phenotype.
k0ka [10]

Answer:

Dominant

Explanation:

The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.

I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.
