What genotype must the person have who possessed the recessive phenotypes?
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
How differences in genotypes cause variations in phenotypes?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
Why phenotypes don't always express its entire genotype?
Phenotypes may not always express the entire genotype due to the presence of dominant and recessive alleles. Dominant alleles mask the expression of recessive alleles in a heterozygous individual, leading to only the dominant phenotype being displayed. Additionally, environmental factors can also influence gene expression and contribute to variations in phenotypes.
Which genetic concepts best explain the fact that hybrid parents can produce offspring with recessive phenotypes?
The concept of recessive alleles and the principle of segregation during gamete formation can explain how hybrid parents carrying a recessive allele can produce offspring with recessive phenotypes. When the alleles for a specific trait segregate during gamete formation, a recessive allele from each parent can combine in the offspring, resulting in the expression of the recessive phenotype.

What was the ratio of dominance to recessive phenotypes in the F2 generation of Mendel's experiments?
3:1

The outward appearance of a particular trait is called?
The outward expression of genetic traits are called phenotypes. Phenotypes expression include recessive and dominant genes such as eye and hair color.

(Apex Learning) 3:1.

How do you deterime phenotypes?
phenotypes are decided by the alleles for that particular characteristic, by a dominant or two recessive alleles. For example, cystic fibrosis has a recessive allele so the phenotype of cystic fibrosis would only appear if there were two of the recessive allele, one from each parent, were present. A heterozygous carrier of the cystic fibrosis allele would show the phenotype of not having cystic fibrosis. So to determine the phenotype simply find out which allele is dominant and find what alleles each parent has the the probability of each phenotype can be calculated
The second generation phenotypes resulting from the cross of true-breeding monohybrid pollination will display a ratio of?
3:1 ratio of dominant to recessive phenotypes.
What is the pedigree of a rare recessive phonotypr determined by a recessive allele?
this question makes no sense.
Why do some human traits show a large number of phenotypes?
i don't know but i think it is because of the recessive and dominate traits.
