Unit of heredity that passes on traits from parent to offspring?
The unit of heredity that passes on traits from parent to offspring is a gene. Genes are segments of DNA that encode specific instructions for the development and functioning of an organism. They are inherited from parents and determine characteristics such as eye color, blood type, and susceptibility to certain diseases.
What is the genotype of a pure-breeding myopic person?
A pure-breeding myopic person, who consistently passes on the myopic trait to their offspring, would typically have a genotype that is homozygous for the myopia allele. This means they would have two copies of the allele associated with myopia, often represented as "mm" if "M" represents the normal vision allele and "m" represents the myopia allele. Thus, their genotype would be "mm."
How many chromosomes dose each parent pass to their offspring?
When a parent is going to have an offspring the offspring only gets half a chromosome from each parent, they combine to make one chromosome then that chromosome gets copied until there are 23 pairs of chromosome's. This is how you get your features.
In humans how many chromosomes does each parent pass on to their off spring?
23 chromosomes are given from each parent.
How are the sets of genes a parent passes down decided?
The sets of genes a parent passes down to their offspring are determined by the genetic material in their sperm or egg cells. During the process of meiosis, genetic material is shuffled and separated into gametes, which combine during fertilization to form the offspring's genetic blueprint. This process results in unique combinations of genes being passed down from each parent to their offspring.
What is the principle that each parent passes only one allele for a trait its offspring?
Segregation
Which hereditary rule explains why a self fertilizing parent that is heterozygous for the A locus can produce offspring that are AA or AA?
This can be explained by Mendel's law of segregation, which states that each parent passes on one allele for each gene to its offspring. In this case, the parent is heterozygous (Aa) at the A locus, so it can pass on either the A allele or the a allele to its offspring with equal probability. Therefore, it can produce offspring that are AA or aa.
One fruit fly is heterozygous for long wings and the other fruit flies home is the core is for short links long wings are dominant to shortenings use the pants where to find the expected percentage of?
If one fruit fly is heterozygous for long wings and the other is homozygous for short wings, the expected percentage of their offspring having long wings would be 50%. This is because when the long-winged parent passes on the dominant long-wing allele and the short-winged parent passes on the recessive short-wing allele, the offspring would have one of each allele, resulting in the offspring having long wings.
Why deos A mother has one allele for dimples and one allele for no dimples What is the probability that she produces a gamete with the allele for dimples?
The probability that the mother produces a gamete with the allele for dimples is 50%. This is because each parent only passes on one of their two alleles for a given trait to their offspring, and in this case, the mother has a 50% chance of passing on the allele for dimples.
What is the nucleic acid that is passes over from parent to offspring?
DNA
Can an ab positive father and an ab positive mother parent an a positive child?
Yes. Both parents have an A allele and a B allele. Each parent can only pass on one of his/her two alleles. If each parent passes an A allele to the child, then the child will have group A blood. If at least one parent passes on an Rh positive allele to the child, then the child would also be type Rh positive. So these two parents could have an A positive child.
Gregor Mendel concluded that a parent passes of the alleles for a trait to their offspring?
One of the allels for a trait to it's offspring.
Type of nucleic acid that passes from parent to offspring and directs all the cells functions?
DNA is the type of nucleic acid that passes from parent to offspring and directs all the cells' functions. It contains the genetic information that determines an organism's traits and characteristics.
If someone cross a purebred mother with type B blood and a father with type AB blood what are the possible blood type outcomes of their offspring?
The possible blood type outcomes of their offspring would be type B or AB. Each parent passes on one blood type allele to their child, so the child could inherit the B allele from the mother and the B or A allele from the father, resulting in blood type B or AB.
If male has type a and female has type ab what are the possible blood types of their offspring?
The blood type will be the same as one of the parents or a combination, so A or AB. If the parents both have the same Rh factor (+ or -) the baby will have that factor, else it could also be either. The risky situation at birth is where the baby's Rh factor is not the same as the mother's.
What is the genotype of a black guinea pig if it is crossed with a whites guinea pig and they have 4 offspring that are black and 2 offspring are white?
The black guinea pig is likely heterozygous (Bb) for coat color, while the white guinea pig is homozygous recessive (bb). The black guinea pig passes on a black allele to all offspring, resulting in 4 black (Bb) and 2 white (bb) offspring.
Is it true that sexual reproduction passes information from a single parent to one offspring?
No. Sexual reproduction passes on a random half of one parent's genetic information and a random half of the other parent's genetic information. This is achieved through meiosis. You are 50% your mom and 50% your dad by genes.
