What are the gametes of TT?

The parent with the genotype Tt has two different alleles, and half of its gametes will have the T allele, and half will have the t allele. So in regard to the Tt genotype, the parent organism will produce two different types of gametes, T and t .

What is phenotype for TT?

The phenotype of a plant with the genotype Tt would be tall. Here tallness (T) is a dominant trait over dwarfness (t), which is recessive. Tallness and dwarfness (stem height) are one of the seven contrasting pairs of traits in pea plants studied by Mendel.

What are the gametes of a genotype?

Genotype refers to the genetic makeup, composition, or structure of a specific organism. Gamete refers to the cell. It can be a male cell. It can be a female cell.

What are gametes?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. … These cells develop into sperm or ova.

What are gametes example?

In short a gamete is an egg cell (female gamete) or a sperm (male gamete). … This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell).

Is TT purebred?

The result of this cross was all tall hybrid pea plants (Tt). When these second-generation plants were crossed, the result was one tall (TT) purebred; two tall (Tt) hybrids; and one short (tt) purebred. Mendel concluded that tallness in pea plants was dominant, and became the expressed trait, (uppercaseT).

Is TT tall or short?

The “TT” and “Tt” crosses both have at least one “T” allele, so they are tall plants. However, the last cross “tt” doesn’t have any “T” alleles and is short, because it is homozygous recessive . Since 1 out of 4 pea plants are short, or 1/4, the probability of a short pea plant from a heterozygous cross is 25%.

Is TT a hybrid genotype?

If the two alleles are the same (TT or tt), the genotype is considered purebred. If the two alleles are different (Tt), the genotype is considered hybrid. This example shows the inheritance of a single characteristic (height). A cross that shows the inheritance of a single characteristic is known as a monohybrid cross.

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.

What are the gamete possibilities of an organism with the genotype TT?

The parent with the genotype Tt has two different alleles, and half of its gametes will have the T allele, and half will have the t allele. So in regard to the Tt genotype, the parent organism will produce two different types of gametes, T and t .
