Karl correns found that when plants with red flowers are mated with plants with white flowers they give plants that have pink flowers why does this happen?

This happens due to incomplete dominance, where the alleles for red and white flowers mix to produce a phenotype that is a blend of both colors (pink). Incomplete dominance occurs when neither allele is fully dominant over the other.


What will be the result in phenotype of two alleles are condominant to each other you can use the example of two flower colors red and white?

When two alleles are co-dominant to each other, it is called complementary factor. For example gene A & B are responsible to contribute red flower color. When present individually in dominant condition, only white flowers are produced. When both these genes combine, the result brings red flowers. Thus when such individuals with white color are crossed, all F1 plants produce red flowers but in F2 generation, the plants segregate in the phenotypic ratio of 9:7. That is 9 plants with red flowers and 7 plants with white flowers.

Why were all of mendels first generation plants tall?

All of Mendel's first-generation plants were tall because they were all homozygous dominant for the trait of tallness. This means they received two dominant alleles for tallness from the parental plants, resulting in expression of the tall phenotype.

Pp, where P represents the dominant allele and p represents the recessive allele.

How do dominant and recessive alleles affect pheno type?

Dominant alleles are always expressed in the phenotype when present, masking the expression of recessive alleles. Recessive alleles are only expressed in the phenotype when two copies are present. This results in a wide range of phenotypic variations depending on the combination of alleles present in an individual.


According to Mendel what kind of genes disappear in F1 pea plants?

According to Mendel's principle of segregation, recessive genes disappear in the F1 generation of pea plants when they are crossed with dominant genes. This is because the dominant gene masks the presence of the recessive gene in the phenotype of the offspring.

If a homozygous dominant plant crossed with a homozygous recessive plant what is the genotype and phenotype of their offspring?

If two homozygous plants with contrasting traits are crossed, the expected genotypes for the offspring will be heterozygous. The dominant trait would be expressed, but they'd be carriers for the recessive trait.

The F1 offspring of Mendel's classic pea cross always looked like opne of the two parental varieties because?

Because Mendel crossed two pure-breeding plants. One being homozygous dominant and one being homozygous recessive. All of the progeny ended up being heterozygous, causing them to take on the dominant phenotype and look like the homozygous dominant parent.


Does a Tt plant have the same genotype as a TT plant?

Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).
