Is it possible for plant breeders to develop a true-breeding pink-flowered snapdragon?

Biology
1 answer:
abruzzese [7]3 years ago
6 0

Answer:

No.

Explanation:

Pink flower colour in snapdragon is as a result of incomplete dominance. The pink flower colour has no allele in nature. Instead, the pink colour results from incomplete dominance of the allele that codes for red flower colour over the allele that codes for the white flower colour.

Assuming that the allele for red flower colour in the plant is R and the allele for white flower colour is r, true breeding red and white flower colour plants will have the genotype RR and rr respectively. In heterozygote state (Rr), the phenotype is usually pink, showing that the R allele has incomplete dominance over the r allele.

<em>Hence, there is no way for plant breeders to develop a true-breeding pink-flowered snapdragon. without some genetic manipulations/mutation.</em>

Snowcat [4.5K]

Answer:

A Jewish couple is about to be married but they both worry about their family history. The man's uncle and the women's aunt died of Tay Sachs disease. Infer why the couple is hiring a genetic counselor analyze their families pedigree.

Reasons are not far-fetched, both intended couple might carry a dominant gene for Tay Sachs disease or one of them has a dominant gene for such, it is pertinent a genetic counselor analyze their family pedegree in order to avoid having such disease or passing it to their offspring.

The chances of either of the intended couple to carry such dominant gene of the disease is imminent.

An E. coli F(+) cell
Phantasy [73]

Answer:

The correct answer will be option- C.

Explanation:

The bacteria can transfer its genetic material through three processes: transformation, conjugation and transduction. The process of conjugation takes place through the formation of the conjugating tube formed of the pili, the membrane extensions of the bacteria.

These pili are known as fertility pili or F-pili as they transfer the F-plasmid or fertility plasmid from the F⁺ bacteria containing the F-plasmid to the F⁻ cells or the bacterial cells which lack the F-plasmid.

Thus, option- C is the correct answer.
