For a monohybrid cross of two true-breeding parents, each parent contributes one type of allele. In this case, only one genotype is possible. All offspring are Yy and have yellow seeds. … Therefore, the offspring can potentially have one of four allele combinations: YY, Yy, yY, or yy.
What are the genotypes of the parents in the monohybrid cross?
Answer Expert Verified
As you can see in the diagram presented below, the correct genotypes of the parents are TT and Tt. Each parent give its children only one chromosome of the chromosome pair, therefore only one allele of the gene.
What is the genotype of monohybrid cross?
A monohybrid cross is a genetic mix between two individuals who have homozygous genotypes, or genotypes that have completely dominant or completely recessive alleles, which result in opposite phenotypes for a certain genetic trait. Typically, this mix determines the dominant genotype. …
What do you call the offspring of a cross between the first parental P1 generation?
The offspring of the P1 generation are the F1 generation (first filial). The self-fertilizing F1 generation produced the F2 generation (second filial).
Are Monohybrid crosses and Punnett squares the same?
For a monohybrid cross (Table below), individual alleles are used, whereas for a dihybrid cross (Table below), pairs of alleles are used. A Punnett square for a monohybrid cross is divided into four squares, whereas a Punnett square for a dihybrid cross is divided into 16 squares.
Who is known as father of genetics?
Gregor Mendel. Gregor Mendel’s work in pea led to our understanding of the foundational principles of inheritance. The Father of Genetics. Like many great artists, the work of Gregor Mendel was not appreciated until after his death.
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 do you determine a genotype?
A Punnett square is one of the simplest ways to determine genotype. The square is actually a mini-chart used to determine the potential genotype for an offspring with respect to particular trait.
