How can two offspring from the same parents have different phenotypes?
In other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous (“hetero” meaning “different”) for that allele. Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive.
How are offspring different from their parents?
In asexual reproduction all the genes in the offspring come from one parent. In sexual reproduction one full set of the genes come from each parent. Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents.
How does the genetic code of the offspring differ from its parents what process makes children different than their parents?
The genetic information passed from parent to offspring is contained in genes carried by chromosomes in the nucleus. Sexual reproduction produces offspring that resemble their parents, but are not identical to them. Asexual reproduction produces offspring – clones – which are genetically identical to their parents.
How are phenotype and reproduction related?
Selection acts on phenotypes because differential reproduction and survivorship depend on phenotype. If the phenotype affecting reproduction or survivorship is genetically based, then selection can winnow out genotypes indirectly by winnowing out phenotypes.
How can identical twins have different phenotypes?
This uniqueness is a result of the interaction between our genetic make-up, inherited from our parents, and environmental influences from the moment we are conceived. As a result, identical twins share identical DNA but may show differences in their phenotype due to environmental factors.
Why do monozygotic twins have different phenotypes quizlet?
Why do monozygotic twins have different phenotypes? They have only minor phenotypic variation across a few physical traits but no differences in psychological traits.
Why the offspring produced by the same parent are different in appearance?
The answer has to do with the fact that each parent actually has two different sets of genes. And that each parent passes only half of their genes to their child. And that the half that gets passed down is random. All of this together ensures that each child ends up with a different, unique set of genes.
Why do offspring look similar to their parents?
Children often look like some combination of their parents. This is because each parent gives the child some of themselves {gene}. A child is made from the information found in the cells of the parents. The specific genes found on these chromosomes make up what is called that person’s genotype.
Why are offspring similar to their parents yet somewhat different from each parent?
In humans, each person has two copies of each type of chromosome. That means they have two copies of each gene, but a person will give only one of these genes to their child. So children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children.
What are the phenotypes of the offspring?
Eye color, hair color, pod shape, and flower position are all examples of phenotypes. In this example, it asked you to do a cross between two parents who were homozygous dominant for eye color. Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene.
Do identical twins have the same genotype and phenotype?
Monozygotic or identical twins occur when a fertilized egg splits apart in the first two weeks of development. The result is the creation of two separate, but genetically identical offspring. That is, they possess the same genotype and often the same phenotype.
How are offspring of sexual reproduction identical to their parents?
Offspring resulting from sexual reproduction are not identical to either parent, because half of the offspring’s genes come from one parent, and the other half comes from the other parent. Does sexual reproduction produce offspring that are identical to the parent? yes How do sexual and asexual reproduction differ in inherited genetic material?
When do two genotypes mate and reproduce offspring?
When these two genotypes mate and reproduce offspring have the potential to have one of the parents genotypes or essentially a combination of their parents genotypes which would look like A1A2. In the big picture the genotypes are recognized as the following A1 A1, A2 A2, or A1 A2.
How are alleles and phenotypes passed from parent to offspring?
Alleles, Genotype & Phenotype. An allele is a particular form of a gene and they are passed from parents to their offspring. A genotype is the combination of two alleles, one received from each parent. The physical expression of a genotype is called the phenotype. The specific combination of the two alleles…
How does sexual reproduction differ from asexual reproduction?
Asexual offspring’s are clones of the parent and carry only the parents genes. Sexual reproduction producesoffspring from both parents and have the genes of each parent. Why does sexual reproduction provide more opportunities for genetic variation than asexual reproduction?
