Let's continue with these two genes that control the color and texture of tomatoes. Allele "R" generates a red coloration, and is dominant. Allele "r" generates a green coloration and is recessive. Allele "S" generates a smooth texture, and is dominant. Allele "s" generates a rough texture and is recessive. You now decide to cross your dihybrid RrSs but this one with a tomato with Rrss. RrSs x Rrss What is the probability of getting Red tomatoes with Rough texture in this new cross? Assume complete dominance and 100% penetrance and expressivity.

ABO blood group is co-dominant for AB and O is recessive. Rh (+/-) factor is completely dominant. A man with O/positive blood and a woman with A/negative blood have six children. All of their children have A + blood type. What can you conclude about the parents’ genotypes? Group of answer choices Both mother and father are likely homozygous at both loci Mother was homozygous at the ABO locus but heterozygous at the Rh factor locus Father was homozygous at the ABO locus but heterozygous at the Rh factor locus Mother was heterozygous at both loci
Can you please not type the answer can you write it on a paper
determine if the possible alleles are complete dominate, incomplete dominance, or codominance.
A farmer is interested in a new colour pattern in his breed of cattle. This trait is controlled by a single autosomal gene (Gene R) with two alleles. The R-allele results in a spotted colour pattern, while the recessive allele causes a solid colour. The farmer has a cow that has the spotted pattern. Can you suggest how the farmer can determine the genotype (RR or Rr) of his cow in a single cross? Describe this cross and provide details on how you would interpret the results.
In the red backed vole (a small mouse-like mammal) there are two traits under investigation. The first trait is a distinct tuft of long hairs at the tip of the tail with a tufted tail being recessive to non-tufted tail. The letter T is used to represent the tail tuft gene. The second trait is a patch of red fur on the head which is known to be recessive to the more common lack of a red patch. The letter R is used to represent this trait. A female to be used in the cross was drawn from a pure breeding line that consistently has both the red patch on the head and a tufted tail. The female is to be crossed with a male from a highly variable wild population. The male used had no red head patch and a normal (untufted) tail. The results were as follows: 7 red head patch with tail tuft, 8 no red head patch with tail tuft, 8 red head patch without tail tuft, 8 no red head patch without tail tuft. What would the results be if the male was crossed with a female that was known to be…
It would be nice if you can give me some explanation please Number 6
Part A) You cross a fly with straight wings with a fly with curved wings to produce the F1 generation, all of which exhibit straight wings. In the F2 generation, you observe 65 straight-winged flies and 16 curved-wing flies. Based upon the results, which phenotype is recessive? Part B) You think this trait is controlled by a single gene, but the F2 numbers don’t quite match a 3:1 expected ratio. Perform a chi-square analysis to determine if the variation you observe is due to chance or not. Based upon this determination, would you keep or reject the “null hypothesis”? Show your work and explain your reasoning.
The Answer is "A" but can you tell me why the answer isn't also "C"
