What is the phenotype of TTRr?
Let the gene for red-flowered be represented by ‘R’ and that of white-flowered be represented by gene ‘r’. Then, the genotypes of the parents would be Heterozygous tall, red-flowered- TTRr and Homozygous dwarf, white-flowered – ttrr.
What is TTRr and TTRr?
Let us consider TTRr as male gametes and ttrr as female gametes. TTRr gives 4 alleles (TR, Tr, TR, Tr) and ttrr gives tr, tr, tr, tr. When this both male and female gametes are crossed, it resulted in 16 progenies.
How do you determine genotypes?
The frequency of genotype AA is determined by squaring the allele frequency A. The frequency of genotype Aa is determined by multiplying 2 times the frequency of A times the frequency of a. The frequency of aa is determined by squaring a….
| Genotype | Expected Frequency |
|---|---|
| Aa or A1A2 | pq + pq (or 2pq) |
| aa or A2A2 | q * q = q2 |
What is the proportion of genotype AABbCC in resulting generation by selfing a plant having the genotype AABbCC?
1 : 2 : 1
AABbCC will produce two type of gametes ABC and AbC. Thus in F, generation three genotypes will be obtained. These are AABBCC, AABbCC and AAbbCC in the ratio of 1 : 2 : 1. Phenotypically AABBCC and AABbCC are same.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What is genotype in genetics?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ.
What is genotype answer?
Genotype. = A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules.
