Is genotype A heterozygous AA?
Individuals with genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus).
What is the genotype of two heterozygous?
The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). … The heterozygotes have a phenotype distinct from normal cats.
What is an example of a heterozygous genotype letters?
Heterozygous refers to a genotype with two different alleles (i.e. Bb, Rr, etc.) and homozygous refers to a genotype with two of the same alleles (i.e. BB, bb, etc.). We can make an even further distinction by saying something is homozygous dominant (BB) or homozygous recessive (bb).
Is the genotype DD heterozygous?
Susan’s genotype is “Dd”, so she is considered HETEROZYGOUS (has two different alleles for a specific gene). Although Susan has both the allele “D” to make dimples and the allele “d” in her genotype, her phenotype is the presence of dimples.
What is the genotype?
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. … Each pair of alleles represents the genotype of a specific gene. For example, in sweet pea plants, the gene for flower color has two alleles.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What is the genotype of the heterozygous offspring?
Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.
