One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous (“homo” meaning “same”) for that allele.
What alleles will the offspring have?
Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype. Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype.
What is an offspring in genetics?
In biology, offspring are the young born of living organisms, produced either by a single organism or, in the case of sexual reproduction, two organisms. … An important aspect of the formation of the parent offspring is the chromosome, which is a structure of DNA which contains many genes.
What type of gene is an allele?
Gene vs allele: chart
|Definition||A section of DNA that encodes for a certain trait||A variant form of a gene|
|Role||Genes determine individual traits||Alleles contribute the diversity in phenotype expression|
|Determines||An organism’s genotype||An organism’s phenotype|
|Number per genus locus||One||Two|
How many alleles are passed down to offspring?
In most cases in the plant and animal world, individuals have two alleles for each gene; one allele is inherited from their father and the second from their mother. Depending on which alleles an individual has received will determine how their genes are expressed.
Why does each parent contribute one allele to the offspring?
Why does each parent contribute only one allele to the offspring? Because alleles are segregated during meiosis when homologous chromosomes are separated. … What two types of gametes could result from this allele combination?
Which allele is always written first?
The alleles are represented by letters. The letter chosen is usually the first letter of the trait.
