This passage describes the leaf type trait in tomato plants:Tomato leaves come in many types, including regular leaves and potato leaves. Regular leaves are small and have jagged edges. Potato leaves are large and have smooth edges.In a group of tomato plants, some individuals have regular leaves and others have potato leaves. In this group, the gene for the leaf type trait has two alleles. The allele L is for regular leaves, and the allele l is for potato leaves.A certain tomato plant from this group has regular leaves. This plant has one allele for regular leaves and one allele for potato leaves.Based on this information, click the blue words to correct any errors in the text.This tomato plant's genotype for the leaf type trait is regular leaves.This tomato plant is heterozygous for the leaf type gene.This tomato plant's genotype for the leaf type gene is Ll.Submit

In tomato plants, the tall vine allele (T) is dominant to the short vine allele (t).  Two tomato plants are crossed.  Among the offspring plants grown from seed, 50% have tall vines and 50% have short vines.

A particular pea plant has one allele for a tall stem (T) and one allele for a short stem (t). By observing it, you can see that it has a tall stem as well as many other different traits.Using this example, explain the difference between phenotype and genotype. Which one can be observed? Which one helps to determine the other?

What is meant by the term ‘phenotype’? An individual with two identical alleles for a particular characteristicAn individual with two different alleles for a particular characteristicAn individual’s physical appearance for a particular characteristicAn individual’s genetic makeup for a particular characteristic 2What is meant by the term ‘dominant allele’?A gene that is never expressed even if it is present on both chromosomesA gene that is always expressed even if it is only present on one of the chromosomesA genetic mutation A gene that is only expressed if it is present on both chromosomes3The height of pea plants is controlled by a single gene with two alleles: a dominant tall allele (T) and a recessive short allele (t). Which of the following is the genotype of a homozygous dominant pea plant?TtttTXTT 4A pea plant has a heterozygous genotype for height, where the tall allele is dominant. What height would you expect the pea plant to be?Tall The plant would not survive with this genotypeShortMedium height5The chromosomes for determining the gender or sex of a person are known as X and Y. Which of the following is the genotype of a boy?XYXXYXXYY

In tomato plants, the tall vine allele (T) is dominant to the short vine allele (t).  Two tomato plants are crossed.  Among the offspring plants grown from seed, 50% have tall vines and 50% have short vines.What are the most likely genotypes of the parent plants?

Next we examined the phenotypes of two T2 plant lines (desig-nated as line 3-5 and line 3-11). The parental T1 plants of both 3-5 and3-11 contained homozygous deletions in the second exon of the geneencoding SP (Fig. 1a). Breeding an sp allele with a single nucleotidepolymorphism (SNP) in the coding region into tomato cultivars wasinstrumental in enabling the mechanical harvest of fruits16. Similarly,loss of SP function in S. pimpinellifolium resulted in compact plants withreduced height, reduced number of sympodial units and determinategrowth when compared with WT S. pimpinellifolium (Fig. 1b–g).
