sentences: red eye is a dominant trait in fruit flies & sepia eye is a recessive trait in fruit flies & a red eye fruit fly crossed with sepia eye fruit fly produces offspring with sepia eye ->  a dominant red eye male fruit fly crossed with a recessive sepia eye female fruit fly produces offspring with recessive sepia eye  a dominant red eye male fruit fly crossed with a recessive sepia eye female fruit fly produces offspring with recessive sepia eye & red eye is a dominant trait in fruit flies0 & if an offspring has a recessive trait , then each parent has at least one recessive gene ->  each parent fruit fly will have at least one recessive gene  each parent fruit fly will have at least one recessive gene & the dominant red eye male fruit fly is one of the parents ->  the male fruit fly has at least one recessive gene  the male fruit fly has at least one recessive gene & the male fruit fly has dominant red eyes & a fruit fly is a kind of organism & if an organism has dominant trait and one recessive gene for that trait, then the organism contains both dominant and recessive genes ->  the male fruit fly has both dominant and recessive genes  the male fruit fly has both dominant and recessive genes & red eye is a dominant trait in fruit flies1 & a fruit fly is a kind of organism ->  the male fruit fly is heterozygous dominant for the trait  red eye is a dominant trait in fruit flies3 & if a recessive trait is expressed, then the organism only contains recessive genes for that trait & a fruit fly is a kind of organism ->  the female fruit fly only has recessive genes for sepia eyes  the female fruit fly only has recessive genes for sepia eyes & red eye is a dominant trait in fruit flies2 & a fruit fly is a kind of organism ->  the female fruit fly is homozygous recessive for the trait  the male fruit fly is heterozygous dominant for the trait & the female fruit fly is homozygous recessive for the trait -> the male fruit fly is heterozygous dominant and the female fruit fly is homozygous recessive
