What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
What type of traits is inherited if an organism receives recessive alleles?
The trait received is recessive.
In which vertebrates is fertilization exclusively internal?
Fertilization is internal in reptiles, birds, and mammals.
What does the union of the gametes during fertilization leads to the production?
Of a zygote.
Is it true or false that during meiosis the two alleles for each gene stay together?
False. During meiosis, the two alleles for each gene can separate and be distributed to different gametes. This is known as Mendel's law of independent assortment, which allows for new combinations of alleles to be formed in offspring.
Is crossing over takes place in sperms before fertilization?
Crossing over occurs during fertilization. This is the mixing of alleles from each of the parents in order to make the offspring.
A husband and wife have two sons one boy has a straight thumb while the other has a bent thumb what causes the difference?
The brothers have different alleles. They received different alleles from their parents
Why are desivable traits not always passed to offspring?
Fertilization involves a random selection of alleles which are combined.
What separates during meiosis?
The answer to this amazing question is alleles!!!! :) alleles
Why are there more egg and sperm cells produced during external fertilization than during internal fertilization?
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
What unites during fertilization?
During fertilization the sperm unites with the egg. This typically occurs in the fallopian tube.
The fusing together of two gametes at fertilization is?
Gametes fuse together during fertilization.
Is fertilization possible during menstruation?
Not the least
When do alleles separate for the same trait?
During meiosis.
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
What process by which the egg cell and sperm cell unite during sexual reproduction?
No. Fertilization is the joining of an egg and sperm.
Mendel called plants that received different alleles for a trait from each parent?
The answer is: hybrids
