$A$ $1: 1$ phenotypic ratio in a test cross indicates that the

Two pea plants were subjected to cross-pollination. Of the $183$ plants produced in the next generation,$94$ plants were found to be tall and $89$ plants were found to be dwarf. The genotypes of the two parental plants are likely to be

In a Mendelian monohybrid cross,the phenotypic ratio in the $F_2$ generation is $3:1$. How many types of gametes are formed in the $F_1$ generation?

How many types of gametes will be produced by an organism with the genotype $AABbCCDD$?

If two individuals with genotype $Bb$ are crossed and they produce two offspring,what is the probability that the second offspring will show the recessive trait,given that the first offspring shows the dominant trait?
