Answer: incomplete dominance

Explanation:

Incomplete dominance is also referred to as partial dominance or semi dominance. It occurs when the two forms of gene in a trait combine in such a way that one does not have a dominance over the other one. Therefore, there's a blend of both genes in the physical appearance of such organism.

Therefore, a low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice is an example of incomplete dominance.

VladimirAG [237]

Answer:

Explanation:

Symbol          Representation

I-                     laci mutant cannot bind to the operator

Is                    laci mutant always bind to the operator

OC                 Operator mutant that prevent repressors binding

F’                    the wild type operator, O+, and laci gene on a plasmid

L                     lacZYA genes

I+ O+ L+   Inducible

I+ OC L+   Constitutive

I+ OC L+, F’   Constitutive

I- O+ L+, F’   Inducible

Is O+ L+    no transcription

dominant trait.

<h3>What is complete dominance?</h3>

Complete dominance occurs when one of the alleles -the dominant one- completely hides the expression of the other allele -the recessive one- in heterozygous individuals.

Cross: BB   x   Bb

Gametes: B   B     B   b

F1)

50% of the progeny will be homozygous  BB

50% of the progeny will be heterozygous Bb

100% of the progeny will express the dominant trait.    

The correct option is C. All of the offspring will exhibit the dominant trait.
