:) 1. Using the table creating abilities in the text box, make a Punnett square showing what would happen if an organism with the genotypes BbLl and BbLl mated.

2. Using your chart from #1, assume that all offspring with a genotype involving dominant B die off before mating. What genotypes would be left to carry on the species?

3. Mate two of the offspring who are left and show the Punnett square.

4. Mate the remaining two offspring and show the Punnett square.

5. Did the removal of one dominant trait wind up affecting the proliferation of the other dominant trait? Explain.

Explanation:

A Punnett square shows the probability of an offspring with a given genotype resulting from a cross. It does not show actual offspring. ... The probability that the first offspring will have the genotype “aa” is 25% and the probability of the second offspring having the genotype “aa” is still 25%.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
