Concept explainers
To determine:
The possibility of an offspring having both recessive traits when a plant with is crossed with a plant with . Red fruit (R) and tall (T) traits are dominant over recessive traits of yellow fruit (r) and short height (t) of plants.
Introduction:
The dihybrid cross is the cross between the two organisms that carry the same allele for two different traits. The Mendel gave the relationship between the dominant and recessive gene from this concept. The law of independent assortment explains that if the parents are carrying heterozygous alleles for two triats, dominant trait will mask the recessive trait in the generation.
