Each parent produces one kind of gamete with an allele for each trait. The gametes are TG and tg. The F1 generation would all be the same, tall and green with a TtGg genotype. The F1 individuals can produce 4 different types of gametes: TG, Tg, tG, tg.
What are the possible gametes for WW?
In the simplest of terms, no two letters in a gamete can be the same letter of the alphabet. If the genotype of an individual is Ww, the gametes will either contain a W or a w but not both.

What are all possible gametes that can be produced by an individual?
All possible gametes are FG and Fg. Explanation: The individual in a given question has genotype FFGg. It is obvious from the individual’s genotype that it has one pair of contrasting alleles.
What is phenotype example?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
How many types of gametes will be produced by the individual with genotype AaBbCcDdEe?
The number of different possible gametes produced by the diploid genotype (AaBbCcDdEe) is 2 x 2 x 2 x 2 x 2 = 32 (2 for each pair of heterozygous genes).
What is the ratio of phenotype?
A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another. When a researcher would like to obtain the gene expression for generations of an organism, they use the phenotypic ratio obtained from a test cross.
What was Mendel’s ratio?
This 9:3:3:1 phenotypic ratio is the classic Mendelian ratio for a dihybrid cross in which the alleles of two different genes assort independently into gametes. Figure 1: A classic Mendelian example of independent assortment: the 9:3:3:1 phenotypic ratio associated with a dihybrid cross (BbEe × BbEe).
What is a genotypic ratio example?
The genotypic ratio describes the number of times a genotype would appear in the offspring after a test cross. For example, a test cross between two organisms with same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr.
