10 Questions
What is the purpose of studying the genotypes of parents?
To predict the probability of offspring having specific genotypes and phenotypes
In a dihybrid cross Punnett square, why does the number of boxes increase exponentially?
As a result of having two different traits being considered
What does having a 6.25% chance of offspring possessing both homozygous recessive traits indicate?
There is a low probability of both traits being expressed
Why are alleles segregated in sperm and egg cells during sexual reproduction?
To ensure each gamete carries only one allele for each trait
How does knowing the alleles of parents help in predicting genetic disorders in offspring?
It enables the identification of potential genetic disorders in offspring
What is one outcome of this dihybrid cross with a 56% chance of producing offspring with brown fur and short tails?
Some offspring can have different genotypes despite expressing similar phenotypes
What can be concluded if an offspring's genotype is known but not their parents' genotypes?
Possible genotypes possessed by the parents can be deduced
Why is studying genotypes important for predicting phenotypes in offspring?
It allows for predicting potential genetic disorders in offspring
In a dihybrid cross, what can we infer if an offspring has both homozygous recessive traits?
There is a low probability that both traits will be expressed
How does a Punnett square help geneticists make predictions about offspring?
By demonstrating all possible combinations of alleles in offspring
Learn about Mendel's Law of Segregation which explains how alleles for each gene are segregated during the formation of sex cells. Discover how traits can disappear in one generation only to reappear in a later generation.
