Explanation:
This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).
In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:
RRYY- RY, RY, RY, RY
RrYy- RY, Ry, rY, ry
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:
RRYY (4)
RRYy (4)
RrYY (4)
RrYy (4)
According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.
This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%
Answer:
(B) Only those salamanders with the highest evolutionary fitness will survive the bottleneck event, raising the allelic frequencies of their traits.
Explanation:
Toricha toroso is a type of salamander which lives in the coastal areas of California after the bottleneck event. Bottleneck event is a kind of event in which population of organisms are reduced due to harsh climatic condition. In these harsh climatic condition of the environment, Toricha toroso survive because of the fitness of this salamander. Fitness plays a vital role in the survival of organisms.
<h2>
Correct Answer is (B)</h2>
Explanation:
(B) A response to one biotic factor in the environment.
- Three distinctive natural elements influence the opening and shutting of a plant stoma <em>such as light, water and carbon dioxide fixations. </em>
- Plant stomata close in haziness and when conditions are dry. Since plant cells need carbon dioxide for photosynthesis, carbon dioxide fixations are another key factor.
- The Stomatal pores in plants The solutes inside them by opening and The measure of water and shutting their guard cells utilizing osmotic weight.
- The end goal for plants to deliver vitality and keep up cell work, their cells experience the profoundly complex procedure of photosynthesis. Basic right now the stoma.
- <em>A few ecological elements influence stomata opening, including hormone, light quality and force, air moistness, barometrically CO2 focus, biotic and abiotic stresses.</em>
