In testcross of H_ and hh individuals, you obtain 20 offspring; 10 of these have the dominant phenotype, and 10 have the recessive phenotype. Based on this, the genotype of the H_ individual is a. heterozygous. b. homozygous dominant. c. homozygous recessive d. none of these are correct
35. A testcross (backcross) is used to determine: a. an individual has a dominant or recessive phenotype. b flowers are red, pink, or white c. whether an individual is homozygous or heterozygous. d. what types of offspring could be produced 36. If red flower color is dominant over white and a homozygous red flowered plant was crossed with a homozygous white flowered plant, what percentage of their offspring in the Fi generation would have white flowers? a. b. с. 100%...

Dihybrid Test Cross PpTt x pptt Heterozygous for both genes makes 4 types of gametes: PPTT x pptt Homozygous dominant for both genes makes 1 type of gamete: Homozygous recessive for Homozygous recessive for both genes makes 1 type of gamete: both genes makes 1 type of gamete: All of the offspring will have What type of offspring will the genotype the phenotype result?
When two loci are completely linked, the offspring observed in a dihybrid testcross in the F2 are: a.) all the recombinant types b.) all the parental types c.) 50% of recombinant, and parental types d.) 25% of recombinant types, and 75% parental types e.) None of the above
Mendelian Genetics problems: 1) What are the probabilities of a particular genotype or phenotype for an offspring for the following parental genotypes? a. Monohybrid cross if one parent is homozygous recessive and one parent is homozygous recessive? What if both are heterozygotes? b. Dihybrid cross if one parent is homozygous recessive and one parent is homozygous recessive? What if both are heterozygotes? 2) What are the probabilities that two parents with the genotypes AaBbccDD x AabbCcDd will have an offspring with the...
Please answer with an explaination and square diagram
A dihybrid cross between a plant homozygous for long and smooth leaves and a plant homozygous for short and hairy leaves produces all long smooth F1 offspring. F1 offspring are then crossed to produce an F2 generation. What would you predict for the ratio of F2 phenotypes?
Question 14 3 pts A testcross is used to differentiate between a homozygous dominant organism and one who is heterozygous for the dominant trait by crossing homozygous dominant organism with a heterozygous one and examining their offspring. True False
Color-blindness is an X-linked recessive disorder. Mike is color-blind. His wife, Meg, is homozygous for normal color vision allele. Using Punnett squares, derive and compare the genotypic and phenotypic ratios for the offspring of this marriage. What is Mikes's genotype?
Using a Punnett square cross a homozygous dominant and homozygous recessive parents. What is the probability that one of the offspring will be an albino (this is a recessive trait)? A. 100% B. 50% C. 25% D. 0%
Would a dihybrid cross between a heterozygous parent (BbSs) and a homozygous dominant parent (BBSS) end up as independently assorted genes? The results of offspring would be 100% dominant.
