In snakes, eye color is a sex-linked trait and is found on the X sex chromosome. Red eyes are dominant to black eyes. If a red-eyed male mates with a heterozygous red-eyed female, what percent of their offspring will have black eyes?

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
