Patterns of Inheritance Pre-Lab Worksheet (complete this sheet individually, and turn it in at the start of lab) If the diploid cells of an organism have 90 chromosomes, its gametes will have exactly l0chromosomes. If a gene called G has six different forms, GI, G2, G.3...G6 may be used to designate the different True or false: Dominant alleles are always more common in populations than recessive ones If an organism's genotype is Hh, what are the genotype(s) of gamete(s) it could produce? If a heterozygous organism's appearance is intermediate between that of the two homozygotes, the alleles are exhibiting What is the blood type of a person whose genotype is Ii? Use the notation from section V to write one possible genotype for a pea plant that is both purple-flowered and short. Half of the sperm cells produced by a human male will contain this small chromosome, which is not the same size as the other member of its homologous pair Explain what makes this statement incorrect The Punnett Square shown in Part lIl of the lab write up suggests that if these parents have already produced three healthy children, their fourth child will have Tay-Sachs disease. On the second day of Lab #9, we will also begin the set up for Lab #10, in which we will investigateExplanation / Answer
If a diploid organism has 90 chromosomes, its gametes will have 45 chromosomes (This is due to reduction division in meiosis)
G1,G3,....G6 may be used to designate the different alleles (alleles represent the different forms of the same gene)
True. Dominant alleles are always more common in a population ( The dominant allele is present in homozygous dominant genotypes as well as in the heterozygous genotypes)
If an organism has Hh genotype, the genotype of the gametes wiil be H and h (The organism will produce two types of gametes due to two different alleles)
If a heterozygous organism's appearance is intermediate, the alleles are exhibiting incomplete dominance or partial dominance or semidominance (In this case one allele is not completely dominant on other allele)
Section V is missing
Half the sperm cells produced will contain a small chromosome called as Y chromosome (A male has one X and one Y chromosome. Y is smaller than X)
Part II is missing
