. Which of the following statements best explains why dominant alleles that cause lethal disorders are less common than recessive alleles that cause lethal disorders?
Homework Answers
The dominant lethal allele carrying individual die before they attain the reproductive stage and able to produce offspring. Where as recessive lethal organism becomes adult and attain the maturation stage. Recessive lethal individual can reproduce and produce offspring. That's why there are more recessive lethal allele in a population as compared to dominant lethal allele in a population.

Which of the following statements about Hardy Weinberg equilibrium is true? a. It explains why dominant alleles do not necessarily replace recessive alleles in a population. b. It applies only to populations in which there is gene flow. c. It assumes that populations are small. d. It assumes that individuals prefer to mate with individuals with certain genotypes. e. None of the above. An answer and explanation would be greatly appreciated, thank you!

17) Why are dominant lethal alleles difficult to pass on? What are three circumstances in which dominant lethal alleles can be passed on to future generations? how do dominant lethals usually arise in a population if it is so difficult to pass them on? 18) What does it mean by male mammals being “hemizygous” for sex chromosomes? 19) Select the true statements about sex chromosomes and sex-linked genes.

True or False: there can be carriers for conditions that are inherited through dominant alleles, as well as those inherited through recessive alleles. Select one: True False Which of the following is NOT true regarding dominance/recessiveness relationships of alleles? Select one: O a. The trait of the recessive allele can be expressed but is not evident in a heterozygote. O b. Dominant alleles are not necessarily more common in a population than recessive alleles. O c. They range from complete...

Why do multiple and lethal alleles often result in modifications of the classic Mendelian monohybrid and dihybrid ratios? Select all that apply. Multiple alleles means that there are more than one gene at a given locus. A diploid organism has one gene locus that may be occupied by different alleles of the same gene. This can result in many different phenotypes for traits, which may not follow typical Mendelian ratios. When an essential gene is mutated, it can result in...

3. Which of the following statements best explains why nitrogen gas at STP is less dense than Xe Has at STP? a) Because Xe is a noble gas, there is less tendency for the Xe atoms to repel one another, so they pack more densely in the gas state. b) Xe atoms have a higher mass than N2 molecules, Because both gases at STP have the same number of molecules per unit volume, the Xe gas must be denser, c)...

7. Why do dominant alleles tend to be advantageous and recessive alleles tend to be disadvantageous in most populations? 8. You are studying a population of parrots and you observe that there are two alleles for wing color. Allele 1 codes for green wings and is dominant over allele 2, which codes for red wings. Allele 2 is at a frequency of 70% of the population, what should be the frequency of allele 1 homozygotes? 9. You are studying a...

1) What is the molecular basis of dominant and recessive alleles (for complete dominance; ignore incomplete dominance, epistasis, etc.)? To answer this question, consider the following: a) If alleles are copies of the same gene, why are two types of alleles? What differentiates a dominant allele from a recessive allele (at the molecular level)? Be specific (base pairs, transcription/translation method, protein produced, etc.) b) Why is the phenotype determined by the dominant allele in heterozygous genotype? Be specific. c) What...
