Answers for Biology Corner Codominance and Incomplete Dominance worksheet?
1. In the fruit fly Drosophila melanogaster, vestigial wings and hairy body are produced by two recessive genes located on different chromosomes. The normal alleles, long wings and hairless body, are dominant. Give the genotype and phenotype of F1 progeny obtained from a cross between a vestigial-winged, hairy male and a normal, homozygous female. If the F1 from this cross are permitted to mate randomly among themselves, what phenotypic ratio would be expected in the F2generation?
What part of the body is Squash good for?
Yellow squash contains carotene and therefore is good for the eyes.
What is an example of a trait inside your body that is affected by your genes?
Male pattern baldness is a common genetic condition passed through the X chromosome that a man gets from his mother.
Trait that improves a species chance of survival?
Adaptation is a trait or structure that improves an organism's chance for survival and reproduction. Benthos is organisms that live on or near the ocean bottom, sometimes attached to surfaces.
Why is water balance such an important in maintaining homeostasis?
For homeostasis you need to keep water levels, temperature at the correct level. For example if you have high temperature enzymes can denature. AS well as for the water level,you need to keep it balanced because too much water or too little can lead cells in your body to stop working. Make the links ;) I've got an exam on this wish me good luck :)
What is a reccessive trait?
A recessive trait is a genetic trait that is only expressed when an individual has two copies of the recessive allele. In a heterozygous individual (having one dominant and one recessive allele), the dominant trait will be expressed while the recessive trait remains hidden. Recessive traits typically show up in offspring when both parents carry the recessive allele.
Does the sickle cell recessive trait decrease the body's resistance to malaria?

What is the difference between a dominant trait and a recessive trait?
A dominate trait will most likely take over the recessive.
Drosophila's body weight is testes?
Is it
Who always wins a dominant gene or a recessive gene?
A dominant gene will be expressed over a recessive gene when both are present in an individual. This means that the trait determined by the dominant gene will be expressed in the individual's phenotype.
What is an Dominant allele?
A dominant allele is a gene that holds a certain characteristic that is superior to a recessive allele. The dominant allele ALWAYS has its trait shown in the body of the recipient, except when both alleles in a gene are recessive.
Is it possible for two parents with a yellow body color to have a blue offspring?
If they both are heterozygous and the recessive gene is blue it can happen
Determine the phenotypes for the genotype yellow body color is dominant to blue?
The phenotypes for the genotype "yellow body color is dominant to blue" would be yellow body color for individuals with at least one dominant allele for yellow (Y allele) and blue body color for individuals with two recessive alleles for blue (yy genotype).
If you performed the Drosophila cross LL x ll what phenotypic ratio would you expect among the offspring?
You would expect a 1:1 ratio of offspring with a long body (LL) to offspring with a short body (ll) due to the incomplete dominance of the gene for body length in Drosophila.
A wild type Drosophila fly has long wings gray body and what color eyes?
Red... I think
Why are sex link traits more common in male than females?
Sex-linked traits are more common in males than in females. This because recessive allele in the X chromosome and produces the trait in males.
What is an exampla of a recessive gene?
the type of cells in your body
