Hello everyone please help with these three questions, thanks in advance! 1. What is the difference between a genotype and a phenotype? 2. How are alleles and traits related? Explain using an example. 3. In pea plants, purple flower color (P) is a dominant allele, while white flower color (p) is a recessive allele. If a pea plant has the genotype Pp, what is its phenotype? Explain your answer.

Answer:

Step-by-step explanation:

Answer 1:

Genotype: The genotype is the set of genes in our DNA which is responsible for a particular trait.

Phenotype: The phenotype is the physical expression, or characteristics, of that trait.

Answer 2:

Allele is one member of a pair or series of genes, and a trait is 2 kinds of alleles. An allele can be dominant or recessive, these alleles determine a person traits, whether there a 2 dominant, 2 recessive, or 1 of each.

Answer 3

Its phenotype would be purple, the dominant purple allele suppresses the white recessive allele. For example

Trait Selected Genotype Selected Phenotype

Eyes Ee One eye

Ears RR Elephant ears

Nose nn Human nose

Mouth mm Smiling teeth

Feet aa No claws

Fur ff Short fur

GG homozygous dominant

gg homozygous recessive

Gg heterozygous

Answer:

1) A genotype is how we would represent the phenotype by using letters.an example could be black fur represented as B(dominant) b(recessive)

While a phenotype is the characteristics of an organism. an example could be black fur.

2) Alleles are the alternative forms of one gene, multiple genes lie on one chromosome, and a trait is a character or expression which is carried by an allele in a form of set of genes.

3)the phenotype would be purple because the dominant alway would be represented more than the recessive (hints it is called dominant it gets shown more).

It would be the dominant allele that gets shown because it is a combination between dominant and recessive, so then the dominant trait would always be shown, either through codominance or incomplete dominance.

codominance--- is where both traits are shown at the same time for example a chicken with speckled black and white on the feathers/fur, but they will both be shown at the same time individually and NOT MIXED

incomplete dominance--- is where both traits are shown but not shown separately, they are mixed while being shown at the same time so say a flamingo is red and another flamingo is white their offspring could have an incomplete dominance because they would be shown as a pink flamingo.
