Genetics Answers

A Mrs Romans claims that her child was wrongly identified a4 hospital, so that she took away a wrong baby. Both Romans and her husband are blood group A. The child's blood group is O. Is Romanas justified in her claim? Make a genetic cross using a punnet square to explain your answer.

if 2 Mexicans have a baby and it was born in america. that would make that baby 100% mexican right and thus classifying them as mexican american and white?

Choose an adaptive trait common to more than one species. For example, birds and bats both have wings. Write a 2-3 page Do not copy and paste from any source.

• Describe what makes this trait an adaptation.
• Briefly describe how the trait evolved; e.g., mutation, genetic drift, migration and/or natural selection. Be sure to support your answer with evidence.
• What is the difference between homologous and analogous traits? How does your trait of choice fit either of these descriptions?
• What is convergent and divergent evolution? Describe whether the trait is a result of convergent or divergent evolution.
• Use in-text citation and provide source references for at least 3 sources. The textbook can be one source. When citing articles or other types of documents, follow standard guidelines as introduced on "Citing references in scientific research papers".

Assuming the allele for black hair (B) is completely dominant to blonde hair (b), construct a Punnett square showing the cross between a homozygous black-haired male and a homozygous blond-haired female. What are the phenotypic ratios for the offspring? What are the genotypic ratios? Are the offspring homozygous or heterozygous?

What amino acid is carried by a tRNA with the anticodon, GUA?

CONTINUATION FOR QUESTION #218928

Compose a response to the following questions. Explain your answer using, and fully explaining, the genetic terms and concepts using the Mendel's experiment. Use headers to label each part of your experiment and/or use sentences to introduce each section.  

Form a conclusion: Were the results close to the expected 9:3:3:1 phenotypic ratio? Do the results support the prediction? What might be observed if far fewer plants were used, given that alleles segregate randomly into gametes? Try to imagine growing that many pea plants, and consider the potential for experimental error. For instance, what would happen if it was extremely windy one day? 

Compose a response to the following questions. Explain your answer fully using the genetic terms and concepts by Mendel's experiments. Use headers to label each part of your experiment and/or use sentences to introduce each section. 

1. Test the hypothesis: You cross the dwarf and tall plants and then self-cross the offspring. For best results, this is repeated with hundreds or even thousands of pea plants. What special precautions should be taken in the crosses and in growing the plants? 
2. Analyze your data: You observe the following plant phenotypes in the F2 generation: 2706 tall/inflated, 930 tall/constricted, 888 dwarf/inflated, and 300 dwarf/constricted. Reduce these findings to a ratio and determine if they are consistent with Mendelian laws. 

Discuss the similarities and differences in DNA replication between eukaryotes and prokaryotes. Are the changes in eukaryotes adaptations? Explain.

If from the sick father of an inherited disease and the mother with normal health all the offspring are sick, tell me according to which type of inheritance this disease is transmitted?
