Question

(4:48) which of the following explains the correct way to layout the alleles (the letters) in a dihybrid cross? capital letter goes first, and like letters stay together lower case letter first, and incorporate the letters

Explanation:

In genetics, for a dihybrid cross, when representing alleles, the standard convention is that the capital letter (representing the dominant allele) goes first and alleles of the same gene (like letters) stay together. For example, if we have two genes \(A/a\) (for one trait) and \(B/b\) (for another trait), the possible gametes would be \(AB\), \(Ab\), \(aB\), \(ab\) following the rule of capital letter first and like - letter (same - gene) alleles together. Lower - case letter first is not the correct convention.

Answer:

Capital letter goes first, and like letters stay together.
