What are physical characteristics of an organism that are passed down from on generation to another?
The physical charactersitics that are passes on from one generation to another are called Phenotypes
What are the phenotype of the f2 generation that Mendel observed?
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).
How do geneticists develop a human pedigree?
A human pedigree is developed by showing phenotypes of a particular genetic trait from one generation to the next in a family. ChaCha
How many phenotypes does the trait have?
Aa AA aa If A dominant, two phenotypes.
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
What phenotypes are present in F1 generation?
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).
What are the likely phenotypes of these seeds when they germinate?
about one-fourth will be white and three-fourths green since it is similar to a monohybrid cross between heterozygotes

What was the ratio of dominance to recessive phenotypes in the F2 generation of Mendel's experiments?
3:1

What was the ratio of dominant to recessive phenotypes in the F2 generation of Mendel's experiments?
(Apex Learning) 3:1.
How does natural selection determine which phenotype are favorable?
they are evident in characteristics that have remained from generation to generation as it is thanks to these phenotypes that a species survived and reproduced passing on the advantageous gene.
What happened to the proportions of the two phenotypes as the F1 generation grew from 10 to 100 offspring?
2015 CSI mamen, especialmente MANDY
Why did Mendele pick the pea plant Pisum sativum?
the pea plant is largely self pollinated the pollination can be externally manipulated to ensure that only what we desire is fertilised it has relatively less no. of phenotypes(external characteristics)
In incomplete dominance genotypes can be expected to appear in a ratio of?
The expected phenotype for a Mendal F1 monohybrid cross is 3:1. Looking at heterozygous parents (F1) who share the same dominant trait, e.g. Straight tail.Crossing two heterozygous parents from the F1 generation results in an F2 generation that produces a 75% chance for the appearance of the dominant phenotype, of which two-thirds are heterozygous, and a 25% chance for the appearance of the recessive phenotype, giving the ratio 3;1.Inheritance pattern of dominant and recessive phenotypes when each parent is homozygous for either the dominant or recessive trait. All members of the F1generation are heterozygous and share the same dominant phenotype, while the F2generation exhibits a 3:1 ratio of dominant to recessive phenotypes.
