Which of the following statements is true about monohybrid F1 crosses in Mendelian inheritance?

Question

Quizplus · Accepted Answer

The monohybrid cross is used to determine which of the two alleles of a gene is dominant. The cross begins with the parental generation. One parent is homozygous for one allele (which means it has two of the same allele such as FF or ff), and the other parent is homozygous for the other allele (which means it has one of each allele, such as Ff). The offspring make up the first filial (F1) generation and all individuals are heterozygous (Ff). A cross between two F1 individuals will always mean a cross between two heterozygous individuals.
The offspring of such a cross (Ff x Ff) will result in 75% of offspring expressing the dominant trait (FF and 2xFf) and 25% of the individuals expressing the recessive trait (ff).

They are usually a result of mutations in genes that are essential to growth or development and are a characteristic of normal crosses.
