Answer and Explanation: The correct answer is (a) one phenotype was completely dominant over another. This means that the pea plant will inherit two alleles for a particular gene (one from each parent), however, only one allele will be phenotypically expressed because it is dominant over the other allele.
Why did Mendel continue some of his experiments to the F2 or F3 generation quizlet?
Why did Mendel continue some of his experiments to the F2 or F3 generation? To observe whether or not a recessive trait would appear.
What was the most significant conclusion that Gregor Mendel drew from his experiments with P plants?
So, the correct option is ‘Traits are inherited in discrete units one from each parent‘.
What is the meaning of the terms monohybrid cross and dihybrid cross?
They are monohybrid and dihybrid. A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only. A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.
What do we mean when we use the terms dihybrid cross?
A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.
Which of the following statements correctly describes the terms Monohybrid Cross and Dihybrid cross?
Which of the following statements is correct in describing the terms monohybrid cross and dihybrid cross? A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents.
Which of these crosses will only produce heterozygous offspring?
Answer and Explanation: The correct answer is (b) AA x aa. In this case 100% of the offspring will have the genotype Aa (heterozygous) with the dominant allele as the phenotype.
What are three conclusions that Gregor Mendel made in his research that contributed to the study of genetics?
He formulated several basic genetic laws, including the law of segregation, the law of dominance, and the law of independent assortment, in what became known as Mendelian inheritance.
What are the three conclusions Mendel came to after his research?
Mendel’s studies yielded three “laws” of inheritance: the law of dominance, the law of segregation, and the law of independent assortment. Each of these can be understood through examining the process of meiosis.
What are the important conclusions made by Mendel Make a list of these conclusions?
—and, after analyzing his results, reached two of his most important conclusions: the Law of Segregation, which established that there are dominant and recessive traits passed on randomly from parents to offspring (and provided an alternative to blending inheritance, the dominant theory of the time), and the Law of
Why did the F1 offspring of Mendel’s classic pea cross always look like one of the two parental varieties group of answer choices?
Why did the F1 offspring of Mendel’s classic pea cross always look like one of the two parental varieties? One phenotype was completely dominant over another.
What were the specific observations Mendel noticed in Monohybrid and Dihybrid crosses?
From these results, Mendel inferred that alleles in a pair of genes in a dihybrid cross behave independently of each other which gave rise to Mendel’s second law. It applies to genes on separate chromosomes. The basis for the law is the independent segregation of different chromosomes at meiotic cell division.
What is common between Mendelian monohybrid cross and dihybrid cross?
Similarities Between Monohybrid Cross and Dihybrid Cross
Genes are involved in both monohybrid cross and dihybrid cross. Both crosses study how characteristics are transmitted to the offspring. In both crosses, gene alleles are not considered as linked.
What is the F1 generation in a dihybrid cross?
A Dihybrid cross is a cross between two different organisms where both the parents are heterozygous for two traits, which means they have both dominant and recessive alleles for each trait. F1 generation means Filial 1 generation, which is the resulting offspring from a cross between two different types.
Why is dihybrid cross important?
The dihybrid cross was initially valuable as an experimental test of Mendelian principles, showing that traits may be inherited independently, with each obeying Mendel’s rules. Later, it was a key tool in the mapping of genes to chromosomes and the elucidation of how genes may interact to determine a phenotype.
What is a dihybrid cross and what principle did it prove?
A dihybrid cross is an experiment in genetics in which the phenotypes of two genes are followed through the mating of individuals carrying multiple alleles at those gene loci. Most sexually reproducing organisms carry two copies of each gene, allowing them to carry two different alleles.
Which of the following statements correctly explains the fact that all seven of the pea plants?
Which of the following statements correctly explains the fact that all seven of the pea plant traits studied by Mendel obeyed the principle of independent assortment? All of the genes controlling the traits behaved as if they were on different chromosomes.
Which of the following statements best describes a monohybrid cross?
This is Expert Verified Answer. Answer: A monohybrid cross is a genetic mix between two individuals who have homozygous genotypes, or genotypes that have completely dominant or completely recessive alleles, which result in opposite phenotypes for a certain genetic trait.
Which of the following statements best describes a dihybrid cross *?
Answer and Explanation: The correct statement is b. They are crosses involving one gene with two alleles. A Dihybrid cross involves a cross between two individuals with two traits governed by two different genes that has two alleles each.
What cross will result in half dominant and half recessive phenotype offspring?
the test cross
Tutorial. In the test cross invented by Mendel, the plant with the dominant phenotype is crossed with a plant that is homozygous for the recessive trait. If the unknown is homozygous, all offspring will have the dominant phenotype. If the unknown is heterozygous, half of the offspring will have the recessive phenotype.
What are the chances of the offspring being heterozygous for both seed shape and seed color?
Answer and Explanation: The pea plant is heterozygous for both seed shape and color, therefore, its genotype is SsYy. The possible gametes it can produce are SY, Sy, sY, and ss and each has an equal chance (25%) of being given by the pea plant to its offspring.
