Rajiv Puri invested part of his $\$ 20,000$ inheritance in a mutual fund account that pays $7 \%$ simple interest yearly and the rest in a certificate of deposit that pays $9 \%$ simple interest yearly. At the end of one year, Rajiv's investments earned $\$ 1550$. Find the amount he invested at each rate.

When researchers compared gene expression in normal breast cells and cells from breast cancers, they found that the genes showing the most significant differences in expression encoded signal receptors. Explain why this result is not surprising.

Question 6 Mary takes red roses and crosses them with white roses. All of the offspring end up being pink. What type of inheritance pattern does this reperesent? O Co-Dominance O Multiple Alleles O Polygenic O Incomplete Dominance O Simple Dominance

Poky is a slow-growing mutant strain of the pink bread mold (Neurospora crassa). If poky is crossed to the normal wild-type mold, all the offspring are poky. But if the reciprocal cross is done, all the offspring are wild type. Why does poky display this type of inheritance, and why is it slow growing?

With regard to heterosis, would the following statements be consistent with the dominance hypothesis, the overdominance hypothesis, or both?
A. Strains that have been highly inbred have become monomorphic for one or more recessive alleles that are somewhat detrimental to the organism.
B. Hybrid vigor occurs because highly inbred strains are monomorphic for many genes, whereas hybrids are more likely to be heterozygous for those same genes.
C. If a gene exists in two alleles, hybrids are more vigorous because heterozygosity for the gene is more beneficial than homozygosity of either allele.

An inheritance of $\$24,000$ is to be divided among three trusts, with the second trust receiving twice as much as the first trust. The three trusts pay interest at the rates of $9\%$, $10\%$, and $6\%$ annually respectively, and return a total in interest of $\$2210$ at the end of the first year. How much was invested in each trust?

Two organisms, with genotypes BbDD and BBDd, are mated. Assuming independent assortment of the B/b and D/d genes, write the genotypes of all possible offspring from this cross and use the rules of probability to calculate the chance of each genotype occurring.
