Can males be homozygous?
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.
The anility to roll your tongue (allele T) is dominant to the (allele t) inability to roll your tongue . If mother is a homozygous tongue roller (TT) and father (tt) cant roll his tongue.?
If the mother is homozygous for the ability to roll her tongue (TT) and the father is homozygous for the inability to roll his tongue (tt), all their offspring will inherit one dominant allele (T) from the mother and one recessive allele (t) from the father. As a result, all children will have the genotype Tt, which means they will all be able to roll their tongues. Thus, every child will express the dominant trait of tongue rolling.
What is the blood type of the father if the mother is O plus and the child is A?
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.
How do you use electrophoresis to determine paternity of a baby?
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.
What is the genotype and phenotype ratios for a homozygous dominant female and a homozygous resessive male?
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.
What is the genotype ratio for a father with dimples and a mother with no dimples?
depends... were they homozygous or heterozygous?
Can males be homozygous?
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.
When a mother is A positive and a father is O positive what will baby be?
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
What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?
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.
The anility to roll your tongue (allele T) is dominant to the (allele t) inability to roll your tongue . If mother is a homozygous tongue roller (TT) and father (tt) cant roll his tongue.?
If the mother is homozygous for the ability to roll her tongue (TT) and the father is homozygous for the inability to roll his tongue (tt), all their offspring will inherit one dominant allele (T) from the mother and one recessive allele (t) from the father. As a result, all children will have the genotype Tt, which means they will all be able to roll their tongues. Thus, every child will express the dominant trait of tongue rolling.
If the mother has 0 blood type and the father has b blood type what blood type will the baby have?
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.
Which term describes the example below- A child with no freckles has a mother who has freckles and is heterozygous and a father who has no freckles and is homozygous recessive?
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.
What is the length ofa newborn baby horse?
that depends on the breed, the mother and father
What is the relationship with our daughter to our grandchildren?
Father or Mother
What is a grandpa?
A grandpa is a grandfather, the father of your father or mother.
If a child has blood type O and its mother has type O could a man with type B be the father?
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.
Can a blood type b negative man father a blood type a positive child?
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.
