Animals dont need to breed to survive for themselves, but they do need food, water and shelter
is that whats being asked? this is a bit confusing
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
Answer:
Barrier island
Explanation:
Barrier islands represent a class of coastal landform composed of sand and sediments that forms parallel to the coast. These islands are constantly changing, being shaped by different factors which include water currents (ocean currents), erosion and waves. Some of the most important parameters that influence the length and width of barriers are tidal range (i.e., the height difference between high tide and low tide), wave energy (i.e., the energy restrained from oceanic waves), the amount of sediment supply and sea-level trends.
