The F1 offspring of Mendel's classic pea cross always looked like opne of the two parental varieties because?
Because Mendel crossed two pure-breeding plants. One being homozygous dominant and one being homozygous recessive. All of the progeny ended up being heterozygous, causing them to take on the dominant phenotype and look like the homozygous dominant parent.
What else can I help you with?
What alleles do the f1 offspring have and why?
The alleles of the f1 offspring will depend on the alleles of the parents. In theory all of the alleles in the parental genotypes could be present in the f1 generation.To work out which combinations of alleles will be present in the f1 generation/the proportion with one allele etc. you would need to draw some kind of cross.AA x AaA AA AA AAa aA aASo the f1 offspring have both the A and a alleles, because the two alleles from each parent are separated into the gametesAA gives two gametes both with 'A' alleleAa gives on gamete with 'A' and one with 'a'
Why is the offspring not identical to parent in asexual reproduction?
The offspring is not identical to parent in sexual reproduction because sexual reproduction produces an offspring that is genetically different from the parents. ---- The answer above is actually incorrect. The offspring is identical genetically to the parent because mitosis produces cells genetically identical to the parent cell or cells. But the offspring itself is not identical.
What happens to the recessive allele in a heterozygous offspring?
In a heterozygous offspring, the recessive allele is present but not expressed because the dominant allele masks its effects.
Is it possible for a human and a gorilla to reproduce and have offspring together?
No, it is not possible for a human and a gorilla to reproduce and have offspring together because they are different species with incompatible genetics.
How are pink four o'clock flowers examples of incomplete dominance?
Pink four o'clock flowers exhibit incomplete dominance because the offspring do not show a clear blending of the parental traits. In incomplete dominance, one allele is not completely dominant over the other, resulting in a phenotype that is a mix of the two parental traits. This is why pink four o'clock flowers, a result of crossing red and white flowers, show an intermediate pink color instead of a blend of the parental colors.
Why was it important to Mendels work that peas were true breeding?
because it helped Mendel discover which plants would be crossed to produce offspring.
Kind of trait that seemed to vanish in the offspring produced in mendels first expiriment?
This was the recessive trait - because the plant had to have two copies for this trait to show, the one dominant copy masked the recessive copy.
Why were all of mendels first generation plants tall?
All of Mendel's first-generation plants were tall because they were all homozygous dominant for the trait of tallness. This means they received two dominant alleles for tallness from the parental plants, resulting in expression of the tall phenotype.
Does your analysis support or refute mendels hypothesis of dominant and recessive inheritance?
You are from Kerr. The answer is on the textbook. The analysis does support the hypothesis because some of the offspring's genotype is heterozygous, as they have two different alleles. They do not have the recessive traits expressed, except in organisms that are homozygous recessive. You're so welcome.
Are frogs r or K selected organisms?
frogs are r-selected because they produce many offspring but only a few of them survive. There is no parental investment and they become reproductively active early in their life cycle.
What are the exceptions to the rule of mendels principles?
a scientific answer that all doctors should know
How many phenotypically different types of offspring are possible in a dihybrid cross between two heterozygous individuals?
In a dihybrid cross between two heterozygous individuals, there are 16 phenotypically different types of offspring possible. This is because there are 2^4 = 16 possible combinations of alleles that can be inherited from the parental generation.
How are plant offspring like their parents and why does this happen?
Plants are offspring like their parents because of their parents DNA this happens because of fertilization
Which of mendels principles is most important in explaining the production of males and females?
because thats how we can do it haha i dont even know this answer
Why do lions have fewer offspring then fish?
Lions have fewer offspring compared to fish because they invest more time and resources in raising each offspring. Lions give birth to only a few cubs at a time and care for them extensively, whereas fish produce hundreds or even thousands of eggs at once with little to no parental care, relying on the sheer number of offspring to increase their chances of survival.
Why blending inheritance is an incorrect hypothesis?
Blending inheritance is considered incorrect because it suggests that offspring inherit a mix of parental traits that blend together, leading to a loss of variation across generations. In reality, inheritance is controlled by discrete units of heredity (genes) that are passed on intact from parents to offspring. This mechanism allows for the preservation of genetic variability within populations.
Why do animals eat their offspring?
Because they are tasty
