It decreases the probability that the gamete will receive a dominant allele for pea shape. D. Heredity 58. Guinea pig coat color is determined by a single gene. The allele for black coat color is dominant to brown. In a cross between two black-haired guinea pigs, 20 offspring are born. If both parents were heterozygous, probability would predict that approximately how many of the 20 offspring would have brown hair? A. 10 15 B. 5 C. D. 0 Mutations & Genetic Variability 59. Errors that are made during DNA replication may result in A. identical twins. B. a viral infection. C. mutations. radioactive decay. D. Mutations & Genetic Variability 60. An organism's describes its specific combination of alleles. For example, an genotype Aa genotype is heterozygous for the allele.

Genotypic variation occurs when alleles are randomly sorted during sexual reproduction. A. Genotypic variation only occurs during binary fission. B. Genotypic variation occurs when alleles are randomly sorted during asexual reproduction. C.
