Number of different types of gametes produced by male or female individual depends on number of heterozygous pair. Since number of homozygous pair equal to 4 hence number of heterozygous pair equal to 6.
A particular species of grasshopper has 10 gene pairs. Of these, 4 of the gene pairs...
Question 1a) In a male mouse, we are following 10 genes using a new molecular method to determine if gene pairs are homozygous or heterozygous in sperm cells. How many different sperm cells may be formed if six of the ten gene pairs are homozygous and the remaining four gene pairs are heterozygous in the male parent? a. 20 b. 32 c. 60 d. 64 e. 1024 Question 1b) You set up a cross of a pure line of gerbils...
In an individual heterozygous at a particular gene, how many different alleles of that gene are present in the cell? a. too many b. 1 c. 2 d. 4
A cell has 3 homologous pairs of chromosomes (6 chromosomes total). This cell undergoes meiosis. How many different gametes can form? O 32 08 04 16 none of these What would be the sequence of an RNA strand which is complementary to the DNA sequence 5' AAGAACCC 3'? 3' TTCTTGGG 5 none of these 5' TTCTTGGG 3' 3' UUCUUGGG 5' 5'UUCUUGGG 3
A species of grasshopper normally has 8 chromosomes, 4 of which are acrocentric and 4 of which are metacentric. An unusual grasshopper is discovered and is found to have 7 chromosomes, 5 of which are metacentric and 2 of which are acrocentric. Which of the following is NOT likely to be true of the unusual grasshopper? a. it arose as a result of a Robertsonian translocation b. one of its metacentric chromosome is a translocation chromosome c. one of its...
An individual heterozygous for 4 gene pairs AaBbCcDd was testcrossed to aabbccdd, the following progeny resulted. aBCD 42, Abcd 43, ABCd 143 abcD 142, aBcD 10, AbCd 5, ABcd 314, abCD 301. Can you please explain how to tell which gene pairs are completely linked? I am lost on this concept and have a test soon. Thank you.
A particular plant has a gene for flower color and a gene for height with the following phenotypes: RR: red flower TT: tail Rr, rr: white flower Tt: medium tt: dwarf If two plants (RrTt times RrTt) are crossed, how many phenotypes can be produced in F1? 1 2 4 6 9 Eye color is an autosomal (non-sex) trait. Brown eyes are controlled by a dominant allele, and blue eyes are controlled by a recessive allele. Color blindness is an...
Consider the following matrix that shows the similarities between species are for a particular gene. A small number (e.g., 3) indicates the genes are very similar, in that only 3 amino acids are different. A larger number (e.g., 17) indicates the species are more different. Using this matrix, calculate and draw a similarity tree using UPGMA. Label the branch lengths. Take a photo of your labeled tree and upload it. Cow Mouse Gibbon Orangutan Gorilla Chimp 16 Cow Mouse Gibbon...
Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...
Answer the following questions based on the following scenario Consider a gene with 2 alleles, W1, and W2. Each line is homozygous for its respective allele. When the 2 lines are crossed, all the F1 progeny has a phenotype associated with W2. 1. What is the genotype of the F1? What gametes can if produce? 2. Which allele is dominant? Why? 3. Draw the punnet square associate with a self-fertilization of the F1. 4. What proportion of the offspring will...
