The advantages and disadvantages of the situation in which individuals of some species of bony fishes change sex, some to maintain more males than females and others to maintain more females than males. Introduction: Bony fishes are the great majority of fishes. There are more than 31,000 species of bony fishes present. They are characterized by thin, flexible, and overlapping cycloid or ctenoid scales. They are characterized by the presence of a gill cover or an operculum. Body shape of bony fishes varies as an adaptation to the habitat.

H gene assorts independently from the I gene. Both on autosomes. One man and one woman, both of HhIAIB genotype. Determine the blood type of progeny and fractions out of 16

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
