What is the genotype for yellow seeds and green seeds?
Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color. yy is the homozygous dominant genotype (2 y alleles). The phenotype of this genotype is green seed color.
What is the genotype of a pea plant that has two recessive alleles for seed color?
YY
Which color is dominant green or yellow?
Since yellow is dominant to green, all of the offspring were yellow. The green phenotype had disappeared. I allowed the yellow pea plants to self- fertilize to see what the second generation would look like.
Which seed Colour is dominant?
Explore
| Trait | Dominant Expression | Recessive Expression |
|---|---|---|
| Color of seed albumen (Y) | Yellow | Green |
| Color of flower (P) | Purple | White |
| Form of ripe pods (I) | Inflated | Constricted |
| Color of unripe pods (G) | Green | Yellow |
Why were pea plants used by Mendel?
Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
Why is the round seed shape known as a dominant trait?
In Garden Pea, yellow colour of cotyledons is dominant over green and round shape of seed is dominant over wrinkled. When a plant with yellow and round seeds is crossed with a plant having yellow and wrinkled seeds, the progeny showed segregation for all the four characters.
What is the dominant seed shape?
From the above reasons, it is clear that round seed shape is dominant .
What is the dominant phenotype R wrinkled R round?
Since capital R = round and is dominant that means that RR and Rr will all be round seeds. That means that ¾ or 75% of the offspring produced will be round. Since, wrinkled is rr, then ¼ or 25% of the offspring will be wrinkled. The genotype is the gene make-up of the offspring.
What has the most control of traits and inheritance Brainly?
nucleic acid
In which squares should the phrase green pods appear?
Answer: Green pods phrases should appear in squares A, C, and D. Explanation: Further explanation will be posted as an attachment due to technical difficulties.
Why are fruit flies advantageous in the study of human inheritance?
Scientists often use fruit flies as a method to test hypotheses about human genes. Why are fruit flies advantageous in the study of human inheritance? They reproduce quickly and take up little space.
Why did Gregor Mendel use peas in his experiments quizlet?
Mendel studied pea plants because they reproduced sexually and had traits that were easily observable.
Which is the best example of a hypothesis leading to new experimental methods?
Answer Expert Verified. The best example of hypothesis which leads to new experiment methods was done by Morgan where he used fruit flies. Thomas Hunt Morgan continues on genetic research which is of Gregor Mendel.
Which best describes Mendel’s work with pea plants?
Answer. Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Which scenario breaks the law of segregation?
According to Mendel, this separation takes place in such a way that only one allele of the same gene will be present in each gamete at the end of both meiotic division. Hence, according to this question, a gamete produced which has 2 of the same alleles after meiosis II breaks the law of segregation.
