I would say A. Either tall or short
When Mendel crossed purebred short plants with purebred tall plants, all of the offspring were TALL
The pure-bred tall plant dominated the short
A) There is 3/4 (75%) chance that the offspring will have freckles.
Answer:
(E) bu cv+
Explanation:
Linkage is the phenomena in which two genes present on same chromosome have a tendency to get inherited together.
It is given that the two autosomal genes are linked and in repulsion. This means that the dominant allele of one gene is linked to the recessive allele of another gene and vice versa.
Hence, the parental type gametes will have bu cv+ and bu+ cv combination. Since in linkage parental gametes always appear in higher numbers than recombinant gametes, out of the given options bu cv+ set of genes will be present in most gametes produced by this cockroach.
Answer:
However, a lot of gene regulation occurs at the level of transcription. Bacteria have specific regulatory molecules that control whether a particular gene will be transcribed into mRNA. Often, these molecules act by binding to DNA near the gene and helping or blocking the transcription enzyme, RNA polymerase.
