A cross is performed between a plant with genotype TtYy and a plant with genotype Ttyy. If the two genes independently assort, the probability of that the offspring will be homozygous for gene T is 0.25.
Further Explanation:
Genotype of an organism is referred as genetic makeup. An individual appearance is described by its Phenotype. The phenotype of an organism is depends upon its genotype. If an organism consists of two copies of the identical alleles then the genotype of an organism is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.
A recessive trait is defined as a trait that gets expressed by an individual, when they show a homozygous recessive condition. This means that if an individual showing a recessive trait will definitely possess both the recessive alleles for that trait as recessive trait gets concealed by the presence of allele for dominant trait. According to Law of Independent Assortment the separation of alleles for one gene takes place independently of any other gene.
A plant with genotype TtYy is crossed with a genotype Ttyy of a plant. So, the cross is formulated between both the plant, then the probability of an offspring would be homozygous is 0.25. The punnet square of the cross between both the plants is given below.
