When mendel crossed true breeding tall plants with true breeding short plants all the offspring were tall because?
Tallness is a dominant trait and shortness is a recessive trait according to Mendel's principles of inheritance. When true breeding tall plants (homozygous dominant) are crossed with true breeding short plants (homozygous recessive), all offspring inherit one dominant tall allele, resulting in them being tall.
In pea plants tall (T) plants are dominant over short (t) plants. If a heterozygous (Tt) pea plant is crossed with a homozygous dominant (TT) pea plant all of the resulting pea plants should be tall (?
Dominant Allele
How would a baby change if one parent was homozygous dominant for all the traits and the other parent was heterozygous?
If one parent is homozygous dominant for all traits (carrying two dominant alleles for each trait), and the other parent is heterozygous (carrying one dominant and one recessive allele for each trait), there would be a 100% chance that the baby would inherit the dominant alleles from the homozygous dominant parent. Therefore, the baby would also be heterozygous for all the traits, carrying one dominant and one recessive allele for each trait.
When does a dominant allele control a charteristic?
at all times
Curly hair is recessive and straight hair is dominant A woman with curly hair marries a man who is homozygous dominant for straight hair. What are the outcomes for their children?
All of their children will have straight hair, as the father can only pass on the dominant straight hair allele. The children will inherit one straight hair allele from their father and one curly hair allele from their mother, but the dominant straight hair allele will mask the recessive curly hair allele.

Father with homozygous genes for dominant trait?
This means that the father has two copies of the dominant allele for a particular trait. As a result, all of his offspring will inherit at least one copy of the dominant allele from him. This implies that all his offspring will either express the dominant trait or be carriers of the dominant allele.
What fraction of the progeny of the cross BbTt x BBtt will have black fur and long tails?
50% of the progeny will have black fur and long tails. This is because all of the offspring will inherit at least one dominant B allele for black fur, and 50% will inherit a dominant T allele for long tails.

Dominant Allele
What is dominant and recessive allele?
A dominant allele is an allele where its phenotype will always be represented when the allele for that gene is present. A recessive allele can be masked by a dominant allele when a dominant and recessive allele are present for the same gene. A recessive allele will only present itself when two recessive alleles for a trait are present.
What type of allele is in the all of the egg nuclei?
the dominant allele is in all egg nuclei.
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 child will inherit one allele from each parent. Since the mother is homozygous dominant (AA) and the father is homozygous recessive (aa), the child will inherit one dominant allele from the mother and one recessive allele from the father, resulting in a heterozygous genotype (Aa).
How would a baby change if one parent was homozygous dominant for all the traits and the other parent was heterozygous?
If one parent is homozygous dominant for all traits (carrying two dominant alleles for each trait), and the other parent is heterozygous (carrying one dominant and one recessive allele for each trait), there would be a 100% chance that the baby would inherit the dominant alleles from the homozygous dominant parent. Therefore, the baby would also be heterozygous for all the traits, carrying one dominant and one recessive allele for each trait.

If the allele for yellow peas is Y the allele for the contrasting trait green peas is?

Curly hair is recessive and straight hair is dominant A woman with curly hair marries a man who is homozygous dominant for straight hair. What are the outcomes for their children?
All of their children will have straight hair, as the father can only pass on the dominant straight hair allele. The children will inherit one straight hair allele from their father and one curly hair allele from their mother, but the dominant straight hair allele will mask the recessive curly hair allele.
What is an allele that expresses itself in a hybrid?
A dominant allele is an allele that will always express itself in a hybrid individual, masking the expression of a recessive allele. This means that if a dominant allele is present, its trait will be visible in the phenotype of the organism.
