An example of natural selection is the red color of a male cardinal. the females of the species choose mates based on the vibrant colors of the males’ feathers. if females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time? increased variation in the shades of red because the selection pressure has been relieved increased variation in the shades of red because the cardinals try different ways to impress the females decreased variation in the shades of red because no form of the trait is advantageous decreased variation in the shades of red because the only reason for variation was selection pressure

increased variation in the shades of red because the cardinals try different ways to impress the females

Explanation:

The color isn’t the choice so there will be more shades

Option D, decreased variation in the shades of red because the only reason for variation was selection pressure

Explanation:

Sexual selection is one of the form of natural selection in which one gender  of a species chooses a mate (opposite gender) based on some specific traits such as tail size, colour, eye types etc. which get diversified ( increase of variation in the specific trait of selection) as these two opposite sexes mate with each other to produce new offspring’s. Now,  the female is choosing the male on basis of some other characteristics other than  the red color of the male cardinal. Thus, the variation of the phenotype “red colour male cardinal “ which was dependent only on the sexual selection pressure will now reduce.  

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.
