The correct answer is B. The parents are heterozygous with polka-dot tails, so they both have Pp genotype. The combination of their genotypes (Pp x Pp) could produce 4 genotypes PP, Pp, Pp and pp. Therefore, there is 25% chance for a PP genotype, 25% for a pp genotype and 50% for a Pp genotype. The PP and Pp genotypes produce a polka-dot tail phenotype and the pp genotype produces a solid coloured tail phenotype. In conclusion, there is 75% chance for a polka-dot tail (25% for a PP + 50% for a Pp) and a 25% for a solid coloured tail phenotype (25% for a pp).
E because i looked on quizlet idk look up the answer sorry
Answer:
True
Explanation:
This is because sacromere is the basic unit of cardiac muscles which is made up of thin and thick filaments. Cardiac muscle is consist of the contractile cells of the heart which it's appearance is striated as a result of alternating thick and thin filaments which is composed of myosin and actin. Actin and myosin are both firm contractile protein filaments, the actin form the thin filaments, and myosin form thick filaments.
This is referring to meiosis, which happens just once to make reproductive cells, unlike mitosis which is just simple copying.
In mitosis, one cell splits into two, but the number of chromosomes doesn't change. The original cell makes two copies of its chromosomes and divides them up.

In <em>meiosis</em>, however, our cell doesn't bother making those two copies. It just takes what it has and divides it between two new cells.
