What words would describe the following genotype TT?
If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero- means different). Phenotype is a way to describe the traits you can see. The genotype is like a recipe for a cake, while the phenotype is like the cake made from the recipe.
Is height a genotype or phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
How are the plant height genotypes TT and TT similar?
Tallness is the recessive trait for plant height; therefore, the genotypes with Tt and TT would have the same phenotype . ... Tallness is a recessive trait in pea plants. C. Tallness is the dominant trait for plant height; therefore, the genotypes with Tt and TT would have the same phenotype.
Does TT mean tall?
| Genotype Definition Example | Heterozygous One dominant allele and one recessive allele Tt | Homozygous dominant Two dominant alleles TT | Homozygous recessive Two recessive alleles tt |

What is the genotype ratio of TT TT?
Complete answer: When cross takes place between Tt and tt two different types of alleles are form, Tt X tt = Tt, Tt, tt, and tt. The genotypic ratio for this cross is 1:1 and the phenotypic ratio is 1:1, where Tt is heterozygous dominant and tt is heterozygous recessive.
What does a TT mean?
The TTY (TeleTYpe), TDD (Telecommunications Device for the Deaf), and TT ( Text Telephone ) acronyms are used interchangeably to refer to any type of text-based telecommunications equipment used by a person who does not have enough functional hearing to understand speech, even with amplification.
Are alleles DNA?
Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits. ... The short answer is that an allele is a variant form of a gene .
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous .
Is YY blue or yellow?
| Homozygous Heterozygous | Genotype YY Yy | Phenotype yellow yellow |

Does height come from Mom or Dad?
As a general rule of thumb, your height can be predicted based on how tall your parents are . If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents. Genes aren’t the sole predictor of a person’s height.
Can two short parents have a tall child?
Yes, short parents regularly do have a tall child . Complete nutrition during development also results in taller children, though not taller than the determining genetic factors. ... Some genetic traits are dominant, recurring in each generation.
Is height only genetic?
The main factor that influences a person’s height is their genetic makeup . However, many other factors can influence height during development, including nutrition, hormones, activity levels, and medical conditions. Scientists believe that genetic makeup, or DNA, is responsible for about 80% of a person’s height.
What are the phenotypes of TT and TT plants?
| Genotype Symbol Genotype Vocab Phenotype | TT homozygous DOMINANT or pure tall tall | Tt heterozygous or hybrid tall | tt homozygous RECESSIVE or pure short short |

Is FF homozygous or heterozygous?
| Genotype Phenotype | F F Homozygous dominant No cystic fibrosis (Normal) | F f Heterozygous Carrier (has no symptoms but carries the recessive allele) | f f Homozygous recessive Cystic fibrosis (has symptoms) |

Is AA homozygous or heterozygous?
If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous. Keep in mind that an organism can’t simply be ‘homozygous,’ period.
