Genetics Question. Thank You

You\'re a beta fish breeder and have noticed that you have a few fish that display a totally novel ruby red coloring pattern. This ruby red color has since become is very popular in your Easy store, but you are STRUGGLING to develop a pure breeding strain. Like, every time two ruby red betas are crossed, you end up with a fair number of ruby reds, but still a significant number of betas featuring the standard-type coloration. In your most recent ruby red x ruby red mating attempt, you ended up with 57 ruby red betas and 28 standard betas. All other such mating. gave similar phenotypic offspring ratios. Explain what\'s going on here. (lessthanorequalto 4 sentences).

Solution

This is because of independent assortment where alleles of two (or more) different genes get sorted into gametes independently of one another. in this phenomenon Homologous chromosomes which are similar but non-identical,

an organism gets one member of the pair from each of its two parents.When homologous pair line up in random orientation at middle of the cell as they separate we are getting gamete with different combination of parental homologue because of the orientation of each pair is random.
