- 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?arrow_forwardWhat is nondisjunction? Why does it cause chromosomal abnormalities? What is aneulploidy? Trisomy? Monosomy? Which kind of monosomy always results in miscarriage in early pregnancy? What do these terms mean: genotype, phenotype, allele, homozygous, heterozygous? Be able to recognize single gene inheritance patterns [autosomal dominant, autosomal recessive, X linked recessive] from a pedigree. Also, how are simple Mendelian traits transmitted? What genotype produces the phenotype? Why do some inheritance patterns result in many more males than females showing the phenotype? What inheritance patterns do Huntington disease and sickle cell anemia, and hemophilia follow (autosomal dominant or autosomal recessive, or X-linked recessive)?

If a man and his wife are both homozygous recessive, will any of their offspring potentially have hitchhikers thumb? What is the man’s genotype and the woman’s genotype? What is the man’s phenotype and the woman’s phenotype? What genotype(s) must the offspring have in order to have the phenotypic trait of hitchhiker’s thumb? Do a cross to determine all potential hitchhiker’s thumb genotypes and phenotypes for the offspring of this man and woman. Is it possible for any offspring of the F1 generation to have hitchhiker’s thumb?arrow_forwardThe human traits described above are said to be controlled by a single gene. Using the character “earlobe attachment”, perform a genetic cross between a heterozygous mother and a homozygous recessive father.

- What do the terms genotype, phenotype, dominant, recessive, homozygous, and heterozygous mean?arrow_forwardA homozygous tall, purple-flowered pea is crossed with short white-flowered pea. Tall and purple-flowered traits are dominant in short and white-flowered traits. Find the genotype and phenotype of the F1 generation. Predict the outcome of F2 generation by crossing the offspring from F1 generation. Give the genotype, phenotype, genotypic ratio, and phenotypic ratio of the F2.arrow_forwardPeople with recessive disorders are usually born to normal parents who are both heterozygotes which means that both parents are carriers of the dominant allele for the disorder but appear normal themselves.
