When Mendel crossed yellow seeded and green seeded pea plants all offspring were yellow seeded?
When Mendel crossed yellow seeded and green seeded pea plants all offspring were yellow seeded?
Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6022 yellow and 2001 green (8023 total). The allele for green seeds has what relationship to the allele for yellow seeds?
What is the genotype of the yellow seeded plant in the P generation?
Yy
Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color.
What is the genotype of the yellow seeded parent?
YY
The dominant seed color is yellow; therefore, the parental genotypes were YY for the plants with yellow seeds and yy for the plants with green seeds.
What happened when Mendel crossed a true-breeding green seeded plant with a true-breeding yellow seeded plant?
When Mendel crossed true-breeding yellow seed plants with true-breeding green seed plants, the offspring were genotypically: made up of a combination of yellow and green alleles.
Why did all of the F1 offspring of Mendel’s purple and white flowered pea cross always look like one of the two parental varieties?
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. traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.
Why did Mendel use true-breeding pea plants?
True-breeding pea plants were important to Mendel’s experiments because the true-breeding pea plants acted as the control group, meaning that Mendel used the true-breeding pea plants to compare the results of his cross-breeding pea plants. Without them, he would have nothing to compare his genetic variations to.
When Mendel crossed a true-breeding yellow seed plant AA with a heterozygous yellow seed plant AA?
If you crossed a true-breeding yellow seed plant (AA) with heterozygous yellow seed plant (Aa): offspring genotypes would be 1 AA : 2 Aa. offspring genotypes would be 1 Aa : 1 aa.
What is the difference between heterozygous and homozygous mixtures?
Homozygous is a genetic condition where an individual inherits the same alleles of a gene from both the parents. Heterozygous is a genetic condition where an individual inherits different alleles of a gene from the two parents.
