What are the phenotype and genotype ratios for a mix between homozygous dominant flower with red (R) pedals and a homozygous recessive flower with white (r) pedals?
RR x rrF1: 100% RrIf complete dominance than phenotype will be 100% red flowersIf incomplete dominance – 100% pink flowers

In humans, if P represents the dominant allele for extra fingers and toes (polydactyly) and p is the recessive 5-fingered allele, which of these genotypes would indicate a person with five fingers?
A person with five fingers will be homozygous recessive and he can have only one genotype possible- pp.PP and Pp genotype would indicate polydactyly.

Does autosomal recessive disease affect the homozygous dominant.
No, it doesn’t. Recessive disease affects only individuals, who have two copies of recessive allele (homozygous recessive). Heterozygotes and dominant homozygotes are not affected by autosomal recessive disease.

Two plants with the genotypes TT and Tt _________________.
a. would have the same phenotype. c. would have different phenotypes.
b. have all dominant alleles d. have all recessive alleles.
a. would have the same phenotypeThe genotypes of both plants are different. One plant has a dominant and a recessive allele (Tt) while another plant has two dominant alleles. However,...

If you cross a homozygous dominant almond shape eyes with homozygous recessive round shape eyes, what is the probability that the offspring will have phenotype of almond shape eyes?
Almond shape eyes - dominant trait, let it be Rround shape eyes - recessive trait, so it will be rThe cross : RR * rrOffspring: Rr (so the phenotype -...

In humans, diabetes is a sex-linked recessive trait. If a homozygous normal woman and a man, whose mother is a diabetic, have children, what will be the phenotypes and genotypes of their children?
If woman is normal homozygous, she has genotype XD XD. If mother of her husband is diabetic, he has genotype XdY and also is diabetic.So if they have children, they...

In rabbits straight ears are dominant to floppy ears. Black eyes are dominant to red eyes. Two rabbits are crossed. SSBB x ssbb what are the parents phenotypes
Phenotype: It is the observable trait in an individual because of the genetic makeup for that trait. Like here, the phenotype i.e. the observable trait in the rabbit are floppy...

. A man who is homozygous dominant for blue hair marries a woman with green hair. They have four children. Predict the children’s’ genotypes and phenotypes
Let's assume that B is a blue hair allele and b is a green hair allele. As a result, the parental genotypes are:Male - BB, possible gametes - B;Female -...

1) In guinea pigs, black fur is dominant over white fur. How could an animal breeder test whether a black guinea pig is homozygous or heterozygous?
If it will be homozygous then all the offspring's of test cross will be of black fur while as if it is heterozygous then black and white fur offspring will...
