Answer:
D. If all of the offspring are short-tailed, the unknown individual is the homozygous dominant genotype.
Explanation:
The short tail phenotype is completely dominant over the long tail phenotype. When a short tailed salamander with unknown genotype is crossed with a homozygous recessive long tailed salamander, the cross is called testcross. Lets assume that the allele "S" gives "short tail" phenotype while the allele "s" gives "long tail" phenotype.
If the "short tailed salamander" with unknown genotype is homozygous dominant (SS), the process of the testcross will express only dominant trait (cross 1). On the other hand, if the "short tailed salamander" with unknown genotype is heterozygous dominant (Ss), segregation of alleles during gamete formation would form two types of gametes (cross 2). The 50% progeny would express the "long tail" phenotype while rest 50% will express the "short tail" phenotype.

Answer:
The correct answer is haploid cells.
Explanation:
A kind of cell differentiation in which the number of chromosomes present in the cell of the parent gets reduced by half and gives rise to four gamete cells is known as meiosis. During sexual reproduction, the process of meiosis is used to generate gametes in the form of sperm and egg cells.
The process of meiosis generally begins in the diploid parent cell, that is, the cell exhibiting two chromosomes copies. In the process, the parent cell goes through the process of replication of DNA, which is followed by two distinguished nuclear division cycles. In the process, the diploid cell, eventually gives rise to haploid daughter cells, which are four in number, showing that each comprising half of the number of chromosomes found in the parent cell, which was diploid.
