What must happen before meiosis can begin
DNA doubles and produces sister chromatids before meiosis
begins.
the chromosomes must replicate
What is the difference between a homozygous trait and a heterozygous trait and can you please provide an example for each
a homozygous trait is when an offspring has either both dominant
genes or both recessive genes from its parents. a heterozygous
trait is when an offspring has both dominant and recessive genes.
for example: a long-tailed cat is dominant and a short-tailed cat
is recessive. the long-tailed cat (homozygous dominant) had
offsprings with the short-tailed cat (homozygous recessive). by
doing the punnett square, 100% of their offspring will be
heterozygous.
Is color blindness a dominant or a recessive trait
Color blindness is a recessive sex linked trait.
Why do more people have attached rather than unattached earlobes
Cause attached earlobes are the dominant trait. Unattached
earlobes are reccessive.
In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation
Wrinkled seeds are recessive
The F1generation carried recessive alleles.
Why did Mendel use purebread pea plants
To validate the results of his experiment.
What would most likely stopped Mendel from finding a pattern is his results
if seed color and shape were located on the same chromosome
A mother has one allele for color blindness and one Allele or normal vision what is the probability that her Gamete Will have the Allele for the color blindness
A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype GGKk. What pos
In a certain plant yellow leaves are dominant (Y) and red leaves are recessive (y). A plant with genotype Yy and a plant with YY are crossed. If they have four offspring how many would you predict wou
the answer is one!! (1) apex
Which best describes probability
the likelihood that something will happen
