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

Biology
1 answer:
abruzzese [7]2 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>

MissTica

Answer:

Both parents have white fur. <em>The only</em> way that this can happen is if their genotypes are both <em>homozygous (bb)</em>. Therefore, both parents pass the (b) allele to every offspring. When you combine two of these alleles, the resulting genotype is <em>(bb);</em> therefore, the resulting  offspring have white fur.

Explanation:

A homozygous trait can be described as a trait in which both the alleles for a gene are similar. A heterozygous trait can be described as a trait in which both the alleles of a gene are different. If an allele masks the effect of another allele, it is said to be dominant. the allele that gets suppressed is termed as recessive.

Hence, for a recessive trait to occur both the alleles of a gene should be homozygous recessive.

        b       b

b       bb     bb

b       bb      bb

I believe the correct answer is natural selection.

Natural competition and the fight for “survival of the fittest” is what pushes diversity the most.

Describe how the egg gets from the ovary to the site of fertilisation.
Vanyuwa [196]

Answer:

The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.

mixas84 [53]

Answer:

The structure of proteins is complex and unique, and only specific molecules can interact with their surface features. The natural shape of each protein is termed the native state. When proteins are exposed to heat, acid, or alcohol, their shape is disrupted and they become nonfunctional or denatured.

Explanation:

Physical agents such as heat, and chemicals such as alcohol and acids cause protein denaturation, that is, a loss of the spatial conformation and structure of the proteins and with this their functionality. Depending on the intensity of the event there may be total loss of function. The three-dimensional structure of a protein is basic for the protein to perform its function correctly.
