You are tall, dark, and handsome but only average in intelligence. You want your future sons and daughters to be intelligent, so you wanted to marry a very intelligent woman. Luckily, you met a woman who is short, fair-skinned, cute, and intelligent, married her and had kids who are what you dreamed them to be. This situation shows what mechanism of evolution? * Recombination Founder effect No answer Gene Flow Random Mating

Which of the following best describes a pair of homologous chromosomes? a- A pair of chromosomes that have the same alleles of the same genes arranged in the same order b- A pair of chromosomes that have the same genes, but arranged in a different order, and with potentially different alleles of some of the genes c- A pair of chromosomes that have different alleles of the same genes arranged in different order d- A pair of chromosomes that have the same genes in the same order, but possibly with different alleles of some of the genes
Over the last several decades, the scientific community has gathered a large amount of information regarding genetics and genetic variation. What is a main source that leads to increased genetic variation? Top of Form Selective breeding Chromosomal mutations Recombination Genetic drift
Eye colors are passed down through generations, but sometimes genetic variations can lead to surprising results in eye colors (dark eye color, still rocks!?) Some examples are found below. Is there truth behind the following? Provide explanations for your answer. Two parents with blue eyes cannot have a brown-eyed child and vice-versa. Eyes with more than one color stems from parents with two different eye colors. People with violet eyes are mutants. People with red or pinkish eye color can have dark-eyed parents.
.what is the purpose of homogenization? it increases the absorption of DNA molecules it decreases the amount of DNA that can be spooled onto a straw it releases the DNA from the nuclei by breaking apart the cell walls, plasma membrane, and nuclear envelopes. it removes attached proteins from DNA it removes attached carbohydrates from DNA - . which of the following is an example of quantitive data? the freshman class of the students contained 643 students, 372 males, and 271 females. the absorption peak of cobalt chloride was 510nm bromelain has optimal enzyme activity at a pH of 7 the color of cobalt chloride was pink the mass of the onion was 50 grams
To what does the term allele refer? Group of answer choices a separate gene at another location on the same chromosome a gene found only in bacteria an alternate version of a gene (same location on chromosome) a linked gene
In sexually reproducing species, each individual begins life with DNA inherited from both parent organisms. , Apply this idea to what occurs when organisms of two species that have homologous chromosomes mate and produce ( F1 ) hybrid offspring. What percentage of the DNA in the F1 hybrids' chromosomes comes from each parent species? As the hybrids mate and produce F2 and later-generation hybrid offspring, describe how recombination and natural selection may affect whether the DNA in hybrid chromosomes is derived from one parent species or the other.
The four chromosomes depicted here are Y chromosomes from men in different parts of the world. The light purple bands represent specific genesthat are identical in all four men. The red bands represent genetic mutations (M) that appeared at different times; M168 appeared about 50,000 years ago, M9 about 40,000 years ago, and M3 about 10,000 years ago. Based on whatyou have learned in this chapter, identify the geographic source of men carrying each of these chromosomes: African, Eurasian, Amerindian, and first migrants out of Africa.
Natural selection means that the environment favors survival of some genotypes. From where does diversity in genotypes come?
If two closely related organisms mate successfully to produce an offspring that is infertile or sterile, how would you classify the parent organisms? They are a) Different species b) Members of the same species c) practicing recombination d) undergoing genetic drift and natural selection
why Recombination Frequencies BetweenTwo Genes Never Exceed 50%
You are studying two genetic loci that are on the same chromosome. One of the loci is a gene that produces darker feathers in dark environments in birds. The second locus is a gene associated with metabolism. In your research you find that the second locus is not under selection, but the first locus is undergoing positive selection. The positive selection at the first locus is increasing a specific allele at the second locus. This discovery of yours is best described as which of the following? a. Recombinaton b. Linkage equilibrium c. Genetic hitchhiking d. Chromosome inversion
You perform a cross between two plants, one MmPp and one mmpp, and obtain offspring with the following phenotypes: 42 MP; 374 Mp; 367 mP; 27 mp. What can you conclude from these data? Group of answer choices The M and P genes are on different chromosomes The recombinant progeny are mP and Mp The M and P genes are far apart on the same chromosome The recombinant progeny are MP and mp
