You inherit two alleles, one maternal and one paternal. Because both parents are homozygous, each only has one variation to pass down. This means that any offspring will be heterozygous and have one allele with a repeat of 200base pairs and one with 400bp.
Yes, males can be homozygous for traits that are located on the sex chromosomes, such as the X and Y chromosomes. For example, a male could be homozygous for a trait on the X chromosome if he inherits the same allele from both his mother and father.
Must be AA, or AO because the mother having O blood, which is homozygous recessive, must be OO. The signs mean little here except the father must carry them and the child inherited them from the father.
When a homozygous dominant female (genotype AA) is crossed with a homozygous recessive male (genotype aa), all offspring will inherit one dominant allele from the mother and one recessive allele from the father, resulting in a genotype of Aa for all offspring. The phenotype ratio will show all offspring displaying the dominant trait. Thus, the genotype ratio is 100% Aa, and the phenotype ratio is 100% expressing the dominant trait.
Children receive half of their genetic material from each parent. There are specific sites on DNA, known as restriction sites, that are recognized by restriction enzymes. These are used to determine paternity. Samples of DNA from the mother, father and child are taken. They are all digested ('cut') by the same restriction enzymes. These DNA fragments are then separated by gel electrophoresis (which separates fragments based on size). The bands of the child are compared to the mother and father's. If the band is not the same as the mother's, it must have come from the father. If these do not match up, then the sample was not taken from the biological father.
Assuming the dystonia is hereditary and is a recessive gene which will be called "d" for simplicity, that means the man must be "dd" and the woman is "Dd". This is the only way they could have a child who is "dd" like the father, but not the mother.
depends... were they homozygous or heterozygous?
Yes, males can be homozygous for traits that are located on the sex chromosomes, such as the X and Y chromosomes. For example, a male could be homozygous for a trait on the X chromosome if he inherits the same allele from both his mother and father.
All babies will be A, if the mother alleles are homozygous (AA) and the other option they will be in 50% A and 50% O if mother alleles are heterozygous (Ai) ,, :) Hope that helps
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.
If the father is homozygous (ii, BB): the baby will be type B. If the father is heterozygous (ii, Bi): the baby will be type B or O.
that depends on the breed, the mother and father
We'llsay F is dominant for freckles and f is recessive for non-freckled. The father is ff The mother is Ff The child is ff. Probability of this cross producing a homozygous recessive child is 50%. There isn't a precise term for this cross.
Father or Mother
A grandpa is a grandfather, the father of your father or mother.
Yes it is possible. Blood type O is recessive. So it is true that the child would need an OO blood type. But if the mother is OO and the father is BO..... Then in this case the mother would contribute an "O" and the father a B or an O. If the father contributes an O then the child will be type O. Of course in order for this to happen the father must be heterozygous and not homozygous for the dominant blood type.
Must be AA, or AO because the mother having O blood, which is homozygous recessive, must be OO. The signs mean little here except the father must carry them and the child inherited them from the father.
Yes, it is possible for a blood type B negative man to father a blood type A positive child. The ABO blood type system is inherited from both parents, with each parent passing on one of their two ABO genes to their child. This means that the child could inherit an A gene from the mother and a B gene from the father, resulting in a blood type of A positive.
