What do you call the physical trait that is displayed?
It is called an expressed trait.
How do wings of penguins and puffins demonstrate convergent evolution?
No. Both are birds and their wings are a derived trait common to all birds. The wings of penguins and bats display convergent evolution.
Why are males most likely to express a sex linked trait?
Males have only one X chromosome, so a recessive X-linked trait will be displayed in the phenotype [visible on the outside]. Females have two X chromosomes, so both of the chromosomes must have the trait for it to be displayed on the phenotype.
Why are males most likely to express a sex linked recessive trait?
Males have only one X chromosome, so a recessive X-linked trait will be displayed in the phenotype [visible on the outside]. Females have two X chromosomes, so both of the chromosomes must have the trait for it to be displayed on the phenotype.
What percentage of offspring in the F2 generation displayed the recessive trait?
50% because it divided half to
When can the phenotype tell you genotype of a trait?
The phenotype can tell the genotype when the characteristic is recessive and is displayed in the individual.
If 675 plants resulting from the cross display a trait controlled by a dominant allele how many plants will show the trait controlled by the recessive allele?
In a gene loci there can be four combinations of 2 alleles. Suppose these possible allele combinations are called D for dominant and R for Recessive. The possible combinations for two of them are DD, DR, RD and RR. Wherever the D occurs the dominant trait will be displayed. There is only 1 where the recessive trait is displayed and this is the last or RR case. There must be 3 times the number of cases of the dominant trait as the recessive so the recessive trait is displayed in 675 / 3 cases or 225
When two of the same alleles are needed to be seen in the offspring's genotype those alleles are what?
Recessive alleles must be homozygous in order for the trait to be displayed phenotypically.
What was Robinson Crusoe's least admirable character trait?
Robinson Crusoe's least admirable character trait was his tendency toward arrogance and stubbornness. He often displayed a lack of humility and a belief in his own superiority, leading him to make rash decisions and overlook the advice of others. This trait contributed to his isolation and conflicts with fellow humans throughout the story.
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
In a Punnett square a capital letter stands for a allele.?
Capital letters on Punnett Squares represent dominant genes, while lowercase letters represent recessive genes. For example, if the trait "T" is a tall gene and the trait "t" is a short gene. When you get your results (if both parents are heterozygous for tallness, Tt) you get four possible results, 1 TT (homozygous tall), 2 Tt (twice, heterozygous tall Tt), and 1 tt (homozygous short). If there is a dominant gene there, that gene will be displayed. Only if there are two recessive genes will the recessive trait be displayed.
