No, not at all. No one factor determines such a complex thing as character.
An offspring receives one blood group allele from each parent. The two alleles inherited by the offspring determines its blood group.
Yes, blood groups are codominant
no
Test Cross.
One way to determine the male's genotype would be to breed him to females with a known genotype of Black-Black. If any resultant calves were born with a white coat, you would then know that the male were Black-White. If calves were consistently black coated, you could be fairly certain he was also of the Black-Black genotype.
In genetics,the phenotype is when genes combine to determine dominant traits
this procedure is generally called a test cross and is used in the agricultural and pet industries lots.
n genetics, a test cross, first introduced by Gregor Mendel, is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. More simply put, test crosses determine the genotype of an individual with a dominant phenotype.
The alleles that are passed from parents to offspring
It is a false statement that "phenotype determines genotype". In fact, it is the opposite. A genotype is the genetics or "instructions" that determine the phenotype. The phenotype is the actual appearance, ex: blue eyes, that is created by a given genotype.
No, genotype actually determines phenotype.
to determine the unknown genotype.
A
Test Cross.
o-
Yes you can accurately determine an organisms genotype by observing it's phenotype, however some phenotypic traits resulting from homozygous or heterozygous combinations of alleles, may make the prediction impossible.
O - . He is rhesus negative
Yes, this is false. It's genotype that determines phenotype. e.g. If you have the dominant gene for brown eyes and the recessive gene for blue eyes (genotype) you will have brown eyes (phenotype)
Make a punnett square
You could cross breed them and depending on what their offspring is, you can determine what their genotype is.
