What else can I help you with?
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
If about 50 percent of the offspring have the dominant phenotype and 50 percent have the recessive phenotype what are the genotype of the parents?
If 50% of the offspring show the dominant phenotype and 50% show the recessive phenotype, it is likely that one parent is heterozygous (Aa) for the trait and the other parent is homozygous recessive (aa). This would result in a 1:1 ratio of offspring showing each phenotype.
Why is it not necessary when the dominant and recessive traits are known to use the term homozygous when referring to the genotype of an individual that has a recessive phenotype?
When the dominant and recessive traits are known, using the term "homozygous" for the recessive phenotype is redundant because it implies that both alleles are the same (rr for a recessive phenotype). It is clear that the individual is homozygous for the recessive allele by observing their phenotype.
Why do we call some alleles dominant?
because it dominates the phenotype
What is the phenotype of a flower in a pea plant that is homozygous recessive?
You would expect 1 homozygous dominant, 2 heterozygous dominant and 1 homozygous recessive offspring. This is because each parent has one dominant and one recessive allele. Therefore there is a 75% chance of a dominant phenotype and a 25% chance of a recessive phenotype.

Would Rr show a dominant or recessive phenotype?
dominant
A man has one recessive allele and one dominant allele. what is his phenotype?
He would have the recessive phenotype for that trait.
What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual exhibit the dominant phenotype?
Given those conditions, the offspring have a 50% chance of demonstrating the dominant phenotype and a 50% chance of demonstrating the recessive phenotype.

What is recessivr allele?
For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent. An individual with one dominant and one recessive allele for a gene will have the dominant phenotype.
Why do we call some alleles dominant?
because it dominates the phenotype
What a recessive trait?
A recessive trait is a trait that is not dominant, and is not really seen in ones phenotype.
Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.
What is the phenotype of a flower in a pea plant that is homozygous recessive?
You would expect 1 homozygous dominant, 2 heterozygous dominant and 1 homozygous recessive offspring. This is because each parent has one dominant and one recessive allele. Therefore there is a 75% chance of a dominant phenotype and a 25% chance of a recessive phenotype.
What is phenotype of Rr?
It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. Is dominant. dominant can be RR or Rr. but when its recessive its rr.
