In pea plants, round seeds are dominant (R) over wrinkled seeds (r), and yellow seeds are also dominant (Y) over green seeds (y). A hybrid round pure yellow pea would have the genotype RrYY, where "Rr" indicates it is heterozygous for the round seed trait and "YY" indicates it is homozygous for the yellow seed trait.
This is one of the classic experiments carried out by Gregor Mendel. If you cross pure-breeding green pod plants with pure-breeding yellow pod plants the offspring (F1 generation) will all have green pods. This means that green pod is dominant and yellow pod is recessive. To explain the results, pure-breeding green pod plants must have the genotype GG (homozygous dominant) and yellow pod plants must be gg (homozygous recessive). When they are crossed the F1 offspring will receive a G allele from the green parent and a g allele from the yellow parent, so they will all have the genotype Gg ie they will be heterozygous.
The farmer can determine if his red tomatoes are pure or hybrid by examining the characteristics of the tomatoes. If all the tomatoes have uniform traits like size, shape, and color, they are likely purebred. If there is variability in the traits among the tomatoes, they are likely hybrids. Alternatively, the farmer can refer to the seed package or contact the supplier for information on whether the tomatoes are pure or hybrid.
The genotype of pure lines refers to individuals that are homozygous for a particular trait, meaning they carry the same alleles for that trait. For example, in a pure line of plants, all individuals would have the same genotype for a specific gene, such as AA or aa. This genetic uniformity is desired in breeding and research to study the effects of specific alleles.
A pure-breeding myopic person, who consistently passes on the myopic trait to their offspring, would typically have a genotype that is homozygous for the myopia allele. This means they would have two copies of the allele associated with myopia, often represented as "mm" if "M" represents the normal vision allele and "m" represents the myopia allele. Thus, their genotype would be "mm."
Hybrids from a cross of parental (P) generation, of homozygous parents (one is homozygous recessive, the second one is homozygous dominant) do belong to F1 generation, yes. Their genotype is heterozygous.
Ex. Genotype = Phenotype AA Pure, no cleft chin Aa Hybrid, no cleft chin AA Pure, cleft chin XX Female XY Male
Mendel crossed a pure-breeding round-seeded variety with a pure-breeding wrinkled-seeded one. All the peas produced in the second or hybrid generation were round.
This is one of the classic experiments carried out by Gregor Mendel. If you cross pure-breeding green pod plants with pure-breeding yellow pod plants the offspring (F1 generation) will all have green pods. This means that green pod is dominant and yellow pod is recessive. To explain the results, pure-breeding green pod plants must have the genotype GG (homozygous dominant) and yellow pod plants must be gg (homozygous recessive). When they are crossed the F1 offspring will receive a G allele from the green parent and a g allele from the yellow parent, so they will all have the genotype Gg ie they will be heterozygous.
The genotypes would be: RR, RR, RR, and Rr As for the phenotypes, you cannot tell without knowing what the alleles represent.

The Principle of Dominance states that some alleles are dominant and some alleles are recessive. The dominant trait dominates or presents the expression of the recessive trait. Thus, for round seed: (capital) R - round (small) r - wrinkled RR - pure round Rr - hybrid round rr - pure wrinkled

The genotype of pure lines refers to individuals that are homozygous for a particular trait, meaning they carry the same alleles for that trait. For example, in a pure line of plants, all individuals would have the same genotype for a specific gene, such as AA or aa. This genetic uniformity is desired in breeding and research to study the effects of specific alleles.
The complex combination of pure topologies is called a Hybrid. Examples of hybrid are star ring network and star bus network.
A hybrid is a breed between two are more animals , like a zonkey( hybrid between zebra and donkey) a pure bred imwould be just a zebra or just a donkey.
Yes, definitely.
