What should be the genotype and phenotype for the parent cattle be if the farmer wanted only cattle with red fur?

Red. Red is the most recessive gene in coat colouration in cattle, thus the parents can only be homozygous red in order to give a red calf. If red as mixed with another gene, like white or black, it would not show in the calf completely or not show at all, respectively. Thus, the bull must be homozygous red (rr) and the cow must be homozygous red (rr) in order to produce red offspring.

What was the genotype of the offspring that did not share the parent's phenotype?
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
How do you identify the genotype?
normal sexual cross pollination - each parent plant contributes traits from its genotype (which are expressed as the 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 the phenotype is recessive then the genotype must be dd.
How can a test cross reveal the genotype of a parent whose phenotype is dominant?
Try using a Punnett Square.
What is receiving physical characteristics from a parent called?
That is most likely called the phenotype, as apposed to the genotype of the offspring.
What is a genotype for the first parent?
well, genotype can be the two alleles for any given gene, while phenotype is the actual (observable) expression of that gene.
What blood type would a baby have if both parents have blood type O positive?
The gene for blood type O is recessive. The mother can only have the phenotype O if she has the genotype OO. The gene for blood type B is dominant, the father has the phenotype B, but can have the genotype BB or BO. If the father is genotype BB, the child will be B + O = BO genotype; hence B phenotype. If the father is genotype BO, the child can be B + O = BO genotype; hence B phenotype (50% chance). Or O + O = OO genotype (O phenotype, 50% chance). * Phenotype = displayed trait that can be found with a simple blood test. * Genotype = genetic make up (one part from each parent), this requires a DNA test to be confirmed; however, it can sometimes be deduced by logic.
What is the genotype of the offspring that do not share the parents phenotype?
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.
Can 2 organisms have different genotypes but the same phenotype?
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
Can parent with as and AA genotype give birth to ac genotype?
If the male parent has genotype AS and the female parent has genotype AA what is the offspring?
What are alleles and what are the two forms?
They are traits that are passed on from parent to offspring. There are also two types of alleles; Dominant and recessive.
To produce pea plants that only display recessive phenotype of a trait what must be the genotype of the parent plant?
both must be tt or both must be Tt
