What is the probab with attached earlobes when an individual with attached earlobes mates heterozygous for free earlobes? A)000 25% 0% D) 75% 24) An individual who is homozygous A) expresses the dominant trait B) carries two different alleles for a gene C) carries two copies of the same allele for a gene D) expresses the recessive trait 25) What is the key to the recognition of incomplete dominance? A) The phenotype of the heterozygote falls between the phenotyp tinuous distribution. Synapsis of a homologous chromosome pair is achieved by the formation of two synaptonemal complexes between the two p arms and q arms of each chromosome. It facilitates the genetic recombination by exchanging the genetic information and producing new combinations of alleles.
What genotypic ratio individual with attached earlobes mates with an individual heterozygous fo D) 3:1 23) Attached earlobes are recessive to free earlobes. The crossing over occurs during the prophase 1 of meiosis 1. crossing-over, The breaking and rejoining of homologous (nonsister) chromatids during early meiotic prophase I that results in an exchange of genetic material. This is when two homologous chromosomes come together and exchange some of the genetic material. Transcribed image text: 20) Crossing over during prophase I results in A) nondisjunction B) reciprocal translocation C) duplication D) genetic variation 21) Alleles are described as A) homologous chromosomes environmental factors that affect gene expression Iternate versions of a gene ) alternate phenotypes 22) Attached earlobes are recessive to free earlobes. Crossing over is a process that takes place during prophase I of meiosis.
