Which set of parents most likely produce child with type O blood?
Question 3. Remember, because type O blood results from the homozygous recessive genotype (i i ), the only way to produce a type O child is if both parents provide an O allele (i ). Since the father has blood type A, he must be heterozygous (IA i ).
What percent offspring have orange phenotype parent plants are orange RR ‘) and yellow r/r ‘)?
What percent of offspring are expected to have an orange phenotype if the parent plants are orange (RR’) and yellow (R’R’)? So, the answer is B. 50% of the offspring would have an orange phenotype. Mendel hypothesized that reproductive cells have only one factor for each inherited trait.
What is the chance that the couple will have a child with PKU?
When two carriers conceive a child, there is a one in four (or 25%) chance for each pregnancy that the baby will have PKU.
What are the heterozygous genotypes?
(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
Which of the following parents Cannot produce a child with type O blood?
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter….How are ABO alleles inherited by our children?
| Inherited | Blood type of child |
|---|---|
| O from the mother B from the father | B |
What is the chance that a child of these parents will have blood type B?
Remember, in the ABO blood groups, the phenotype is the blood type of the person. Here, a child born of these parents has a 50% chance of inheriting the type A phenotype, or blood type. The chance he or she will have type AB blood is 25%, and the chance of type B blood is 25%.
How offspring inherit genes from their parents?
One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.
Which statement best supports why many offspring look similar to their parents?
Q. Which statement best supports why many offspring look similar to their parents? Offspring inherit characteristics from one parent.
Who is most likely to get PKU?
In the United States, PKU is most common in people of European or Native American ancestry. It is much less common among people of African, Hispanic, or Asian ancestry.
What is the probability that a child of a heterozygous mother and father will be an albino?
When both parents are heterozygous (Cc) carrier, in each pregnancy there is 25% chance of birth of an albino i.e. 1 in 4. So, in each pregnancy, there is 75% chance of birth of a normal (phenotypic) child i.e. 3 in 4.
What is the father’s genotype?
Potential blood types of father
| Mother’s Blood Type | Possible Mother’s Genotype | Possible Father’s Genotype |
|---|---|---|
| A | AA, AO | AA, AO |
| A | AA, AO | AB |
| A | AA, AO | BB, BO |
| A | AA, AO | OO |
Are the parents homozygous or heterozygous?
Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.
