Solved in 3 steps
- Compare and contrast Maternal effect Maternal inheritance Paternal imprintingList and describe at least two potential consequences to human health due to the paternal-age effect.Define the following terms: gene, allele, dominant, recessive,true-breeding, homozygous, heterozygous, cross-fertilization,and self-fertilization.
- The passing of traits is calledDefine the difference between (a) gene and allele, (b) dominant allele and recessive allele, (c) homozygote and heterozygote, and (d) genotype and phenotype.________________________is the period of development from fertilization to birth, whereas is the period of development from birth to death.
- Use a punnett square to calculate the following: George is the youngest child in a family that includes 4 children. All of the children have the recessive phenotype-attached earlobes. However both parents have unattached earlobes, the dominant trait. Use the letters G, g and answer the following: What is the genotype of the mother? What is the genotype of the father? What percentage of the offspring would express the recessive trait?indicate the stage at which segmentation genes, homeotic genes, and egg-polarity genes would have an effect on development.Describe why polygenic inheritance is much more important that simple single-gene dominant and recessive genetic relationships
