To describe: A genetic explanation for the inheritance pattern of a sickly yellowish trait.
Introduction: According to Mendel's first law of dominance, each gene has two alleles that code for a specific trait. Among these two alleles, one is always dominant, which means that it will always show, while the other allele is recessive meaning its presence can be masked by the dominant allele.
To suggest: A simple test for the inheritance pattern of a sickly yellowish trait.
Introduction: The cross between individuals possessing two pairs of contrasting traits (four alleles) is known as a dihybrid cross. It involves a cross between two true-breeding or pure parents.
To explain: The relationship between chloroplasts and the reduced photosynthesis, sickliness, and yellowish appearance of a plant.
Introduction: The plant organelle chloroplast allows the plant to perform photosynthesis or to make its own food or energy.

- What is a feasible explanation why there is lesser percentage of germination and growth rate in monggo seeds when sprinkled with water added with 3/4 teaspoon as compared to monggo seed set-ups sprinkled with water?arrow_forwardDanish is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover great numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty. Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds.arrow_forwardThis figure summarises the life cycle of a seed plant. The blue circles named A and B represent the sexually mature individual of each phase of the life cycle. 1) What is this life cycle called? 2) Plant B is in the diploid phase. What is another name for this plant? 3) If A is the haploid phase, in which phase would you find sepals? Write just the letter of the individual corresponding to the correct phase 4) If B is the haploid phase, in which phase would you find synergids? Write just the letter of the individual corresponding to the correct phase 5) If B is the diploid phase, in which phase would you find the nucellus? Write just the letter of the individual corresponding to the correct phase 6) If A is the diploid phase, in which phase would you find the sperm cells? Write just the letter of the individual corresponding to the correct phase 7) If A is the diploid phase, in which phase would you find selection on flower colour? Write just the letter of the individual corresponding…arrow_forward
- Banana plants, which are triploid, are seedless and thereforesterile. Propose a possible explanation.arrow_forwardJames is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty.Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds. Remark: The word count limit is 250 words only, no less than 100 words.arrow_forwardThe table shows three related species of potato, and the number of chromosomes each species carries in its somatic cells. S. avilesii is diploid. S. tuberosum is the widely cultivated species. Potatoes propagate by asexual reproduction and do not depend only on gametes for reproduction. Species Number of chromosomes in somatic cells S. tuberosum is likely to be a larger, more vigorous plant than S. avilesii. Classify each statement about these potato species as true or false. Gametes produced by S. microdontum contain 18 chromosomes. S. microdontum is aneuploid. S. microdontum is a triploid with 3x chromosomes. Solanum avilesii True 24 The basic chromosome number (x) for these species is 6. S. tuberosum is a tetraploid with 4x chromosomes. Solanum microdontum 36 The basic chromosome number (x) for these species is 12. S. microdontum could have arisen only from a cross between S. avilesii and S. tuberosum. False Solanum tuberosum 48 S. microdontum could have arisen from a cross between…arrow_forward
- A snapdragon with pink petals, black anthers, and longstems was allowed to self-fertilize. From the resultingseeds, 650 adult plants were obtained. The phenotypesof these offspring are listed here.78 red long tan26 red short tan44 red long black15 red short black39 pink long tan13 pink short tan204 pink long black68 pink short black5 white long tan2 white short tan117 white long black39 white short blacka. Using P for one allele and p for the other, indicatehow flower color is inherited.b. What numbers of red : pink : white would havebeen expected among these 650 plants?c. How are anther color and stem length inherited?d. What was the genotype of the original plant?e. Do any of the three genes show independentassortment?f. For any genes that are linked, indicate the arrangements of the alleles on the homologous chromosomes in the original snapdragon, and estimate thedistance between the genesarrow_forwardRound seed is dominant over wrinkled. Yellow cotyledon is dominant overgreen. Full pod is dominant over constricted. The genes for these traits arefound on separate chromosomes. If a trihybrid plant is self-fertilized, whatproportion of the progeny will have round seeds in constricted pods?Express answer in fraction form.arrow_forwardTomato has diploid chromosomes number of 24.

- Large ear of corn has a total of 433 grains, including 26 Yellow & Shrunken, 73 Purple & Shrunken, 63 Yellow & Smooth, and 271 Purple & Smooth. Determine whether the ratio of corn kernels support the hypothesis that the plant is heterozygous.arrow_forwardA farmer obtained pure seed of wheat variety (Galaxy-13) but unfortunately he has mixed it with other varieties in his field while he was planning to use that seed for next year. Being a plant breeder, suggest a method in detail to the farmer, that how he can get the pure seed again from that mixed lotarrow_forwardBolting is when a plant starts to spend its energy on producing flowers. Initial bolting time is figured by the number of days from germination to bolting. Rosette area is figured by the average rosette area of the plant at the time of bolting. Researchers created strains of A. thaliana to have varying somatic ploidy levels to study the resulting phenotypes. The graphs show how initial bolting time and rosette area relate to the number of chromosomes in each strain’s somatic cells. Which of the following best describes how a change in genotype affects the phenotype of A. thaliana? The largest average change in both phenotypes occurred from the 2n to the 4n strain. The largest average change in both phenotypes occurred from the 4n to the 6n strain. A lesser number of chromosomes results in plants with a later initial bolting time. A greater number of chromosomes results in plants that have larger rosettes areas.arrow_forward
