Codominant
Codiminant principle suggests that a plant with the genotype Tt will display a tall phenotype.

Codominant
A gene that shows maternal effect inheritance is one where the phenotype of the offspring is determined by the genotype of the mother, rather than the offspring's own genotype. This means that even if the offspring carries a certain genetic variant, it will only display the phenotype associated with the mother's genotype.
both must be tt or both must be Tt
both must be tt or both must be Tt
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
The phenotype of a plant with the genotype WW would typically exhibit the dominant trait associated with the W allele. Since the WW genotype consists of two dominant alleles, the plant would display the characteristics linked to that dominant trait, which could include features such as flower color, leaf shape, or growth habit, depending on the specific genetic context.
In a testcross, an individual with a dominant phenotype but unknown genotype is crossed with an individual that is homozygous recessive for the same trait. This helps determine the unknown genotype of the dominant individual based on the phenotypic ratios of the offspring. If any offspring display the recessive phenotype, it indicates that the dominant parent is heterozygous. Conversely, if all offspring show the dominant phenotype, the dominant parent is likely homozygous.
Genes that come together with different alleles are called _____.
Organisms or genotypes that are homozygous for a specific trait and always produce offspring of the same phenotype are said to be true breeding. This means that when bred with another organism of the same genotype for that trait, all offspring will display the same characteristic.
A person who is homozygous dominant for the length of their eyelashes has two identical dominant alleles for that trait. This genotype can be represented as "AA," where "A" signifies the dominant allele. Consequently, this individual will display the dominant phenotype associated with long eyelashes.
