what is the 7 pea characteristics studied by gregor mendel?

Question

its for a science project

Answer 1

yeah charcters are mentioned above.add to your project these characters are present on the four chromosomes that is 1 4 5 7 found by stig blixit.

Answer 2

Are good materials but answers are not clear as I expected. if you look on 7 traits studied by G. Mendel should be classifies well in form of table to describe dominant and recessive alleles for each character. I advice readers of these concepts to find more resources that define in detail the 7 seven traits studied by Mendel, in good order.

Answer 3

Gregor Mendel is famous today but was relatively unknown outside Czechoslovakia in his lifetime. He was the first scientist to deduce clear and rational laws which could explain the process of inheritance. Unfortunately, few medical students are interested in the genetics of peas! However, it turns out that the rules which Mendel deduced from studies of peas are equally applicable to human inheritance and it is convenient to follow his train of logic beginning with characteristics determined by a single gene and moving on to the complications introduced by multiple genes. If you are interested to read a translation of his original paper then
Single gene
Mendel began by collecting varieties of pea which differed from each other in clearly defined ways. The pea flower has anthers and a stamen which are very close together. It will self fertilise in normal cicumstances. It is possible to remove the anthers before they are ready to produce pollen and to cross fertilise the pea plant by bringing pollen from another plant on a paint-brush. Mendel allowed his plants to self fertilise for a number of generations until he was certain that they were true breeding, i.e. that the offspring always resembled the parent for the characteristics under consideration. Then he began his experiments.

Characteristics studied by Mendel
Characteristic
Dominant allele

axial or terminal flowers
axial flowers

round or wrinkled seeds
round seeds

yellow or green seed interiors
yellow interiors

violet or white petals
violet petals

tall or dwarf plants
tall plants

fat or shrunken ripe seed pods
fat pods

green or yellow unripe pods
green pods

First he took a pair of parental strains differing at a single characteristic, for instance, a round seed strain and a wrinkled seed strain, and wisely he intercrossed them in each direction (i.e. "round" pollen onto "wrinkled" stigma and also "wrinkled" pollen onto "round" stigma). In fact it made no difference that he tried each parent as the male or the female but it might have done. The plants resulting from this mating, the first filial generation or F1, were all examined. All had the appearance of one of the parental strains, in this case, the round one. Mendel defined the visible characteristic as the dominant one. The F1 plants were then allowed to self fertilise to produce a second filial generation or F2.
surprising result occured in the F2 generation, wrinkled seeded plants reappeared! Mendel counted more than enough F2 plants to be able to say that the "wrinkled seed" plants were one quarter of the offspring. The characteristic which had disappeared and had now reappeared Mendel described as recessive. Mendel went on to allow each F2 plant to self fertilise. He found that the wrinkled seed plants (and their offspring) were true breeding like the original wrinkled seed parental strain. One third of the round seeded plants were also true breeding (as were their offspring). The remaining two thirds of the round seeded plants behaved exactly like the F1.

The Law of Segregation
The phenomenon could be explained if it were assumed that each plant had two copies of the factor influencing the trait. We now call the factor responsible a gene, we say that more than one form of the gene can exist and we call those alternative forms alleles. Mendel explained the results by suggesting that each plant contained two alleles which did not blend together but which remained unchanged. In the next generation the plants passed one or other allele at random into a gamete to be combined with a gamete from the other parent. The non-blending followed by separation into the next generation is the Rule of Segregation.

We can distinguish in the above cross two sorts of individual, true breeding individuals with both alleles the same, and individuals in which the two alleles continue to segregate. We call the former homozygotes and the latter heterozygotes or carriers. The gene which we are considering is said to be homozygous or heterozygous respectively. We can also distinguish between an individual's outward appearance, its phenotype, and its inward genetic constitution, its genotype.

A convenient method of predicting the relative ratios of the progeny in any cross is by means of a Punnett Square an example of which is shown in the above diagram. The gametes from each parent are placed on the margins and at the intersections of the rows and columns are written the resulting offsprings' geneotypes and, if we wish, their phenotypes.

The Relationship of Genes to Chromosomes
The alternation of two genes in individuals and one gene in gametes is of course reminiscent of the behaviour of chromosomes, diploid in most tissues but haploid in sperm and egg. We now know the reason why this is so, genes are carried on chromosomes, encoded in the DNA.

Answer 4

He studied your mom! OHHHHHH! Lol joking

Answer 5

the seven characters are.........
shape of seed........round / wrinkled
colour of cotyledons......yellow / green
shape of pod..........full / constricted
colour of pod..........green / yellow
position of flower.........axial / terminal
colour of seed coat.......grey / white
height of stem.........tall / dwarf
