75%
There is a 25% chance that the offspring will exhibit polydactyly if both parents are heterozygous for the trait.
To determine if a particular plant is homozygous or heterozygous, you would need to perform a test cross with a homozygous recessive individual. If the offspring display the recessive trait, the original plant would likely be heterozygous. If all offspring exhibit the dominant trait, the original plant would likely be homozygous dominant.
100% of the offspring in a cross between parents with the genotypes EE and EcEc will exhibit cataracts, as all their offspring will inherit at least one copy of the cataract-causing genotype, Ec.
In this case, the genotypic expectancy would be 50% heterozygous and 50% homozygous offspring. The phenotypic expectancy would depend on the specific traits being studied and whether they exhibit dominance or recessiveness. If the trait is dominant, the phenotypic ratio would likely be 100% expressing the dominant trait.
A genotype that is heterozygous means an individual has two different alleles for a particular gene. This can result in a mix of traits or characteristics, earning the term "hybrid" from the blending of genetic information. In cases where one allele is dominant and the other recessive, the individual may not exhibit the recessive trait but can pass it on to offspring, hence being referred to as a "carrier."
Sickle cell disease is an example of codominance, not heterozygous dominance. In individuals who are heterozygous for the sickle cell allele, they exhibit a milder form of the disease called sickle cell trait, which demonstrates codominance of the normal and mutant hemoglobin alleles.
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
To determine if a particular plant is homozygous or heterozygous, you would need to perform a test cross with a homozygous recessive individual. If the offspring display the recessive trait, the original plant would likely be heterozygous. If all offspring exhibit the dominant trait, the original plant would likely be homozygous dominant.

By the process of hybridization, breeders cross two genetically different organisms. The purpose is to have the best traits of both parents.
The individual is called a carrier. This means they carry a recessive allele for a genetic disorder, but they do not exhibit symptoms of the disorder themselves. However, they can pass on the recessive allele to their offspring.
They share the same genes
It does because the corn plants that it reproduced from have the same traits as there offspring.
few offspring and good parental care
Sickle cell disease is an example of codominance, not heterozygous dominance. In individuals who are heterozygous for the sickle cell allele, they exhibit a milder form of the disease called sickle cell trait, which demonstrates codominance of the normal and mutant hemoglobin alleles.
To find the possible phenotypes of offspring, you need to understand the genotypes of the parents and their mode of inheritance. Then, you can use a Punnett square to determine the possible combinations of alleles that can result in different phenotypes in the offspring. By analyzing the genotypes of the parents, you can predict the ratios of different phenotypes that may appear in the offspring.
A heterozygous person is called a carrier for the specific trait or gene they carry. This means they have two different alleles for a particular gene, with one dominant and one recessive allele. It is important to note that being heterozygous for a genetic disorder does not necessarily mean the individual will exhibit symptoms of the disorder.
A person with a heterozygous gene has different alleles for a particular trait, with one dominant and one recessive allele. This individual will exhibit the dominant trait in their phenotype while carrying the recessive allele in their genotype.
