In sexual reproducers, meiosis gives rise to _____________.

White fruit color in summer squash is influenced by a dominant allele W, whereas colored fruit must be ww. In the presence of ww, a dominant gene G results in yellow fruit, and homozygous gg results in green fruit. The F2 phenotypic ratios resulting from a cross of a true-breeding plant with white fruit (genotype WW GG) with a plant with green fruit will result in which phenotypic ratios?

Dolly’s lifespan might have been extended by giving her supplementary ___.

Height, weight, and eye color are examples of phenotypes that illustrate

In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The allele for tall (D) is dominant to the allele for dwarf (d), and the allele for purple (P) is dominant to the allele for white (p). A tall plant with purple flowers crossed with a tall plant with white flowers produces 3/8 tall purple, 1/8 tall white, 3/8 dwarf purple, and 1/8 dwarf white. What is the genotype of the parents?

Chromosome segregation in anaphase I is consistent with which statement?

If a child more strongly resembles one parent’s physical traits than the other parent’s, the explanation could be due to chromosome movements during ________________.

If a diploid organism has a genome consisting of four pairs of homologous chromosomes, it can produce ____ different combinations of maternal and paternal chromosomes in gametes (disregarding crossing over).

In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The allele for tall (D) is dominant to the allele for dwarf (d), and the allele for purple (P) is dominant to the allele for white (p). A tall plant with purple flowers crossed with a dwarf plant with white flowers produces 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white. What is the genotype of the parents?

Protein products of which genes “put the brakes” on the cell cycle when DNA is damaged or incompletely copied?
