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.
Are sex-linked traits that are recessive phenotypes most often seen in men or woman?
men
Are earlobes a recessive gene?
Recessive, but there are gray areas for earlobes that are very rare.
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.

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

men
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.
What was the ratio of dominant to recessive phenotypes in the F2 generation of Mendel's experiments?
(Apex Learning) 3:1.
Are earlobes a recessive gene?
Recessive, but there are gray areas for earlobes that are very rare.
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
If both of the parents have attached earlobes what is their genotype?
The phenotypes of attached and unattached earlobes do not fit neatly into the Mendelian theory of two alleles for one trait, and there is a continuum of earlobe phenotypes. That said, unattached earlobes are a dominant trait, so if the individual is homozygous for unattached earlobes, all of her offspring will have the unattached phenotype, even if some or all of them are heterozygous.
What is the pedigree of a rare recessive phonotypr determined by a recessive allele?
this question makes no sense.
Individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
of two different phenotypes
