Answer:

The correct answer would be -

17. 50% chances of round offspring

18. 25% chances two copies of dominant allele in the genotype of offspring

Step-by-step explanation:

17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.

S for square trait and s for a round trait then

S s

s Ss ss

s Ss ss

Thus, the correct answer is 50 percent as there are only two copies of ss.

18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -

P p

P PP Pp

p Pp pp

There is only one out of four rue-breeding dominant offspring will be produced.
