What else can I help you with?
Mendel observed that pairs of alleles were separated or segregated in gametes and that they were rejoined in fertilization. We know that pairs of are segregated in and then are rejoined through fertil?
Mendel observed that pairs of alleles are segregated during meiosis, the process of gamete formation, where homologous chromosomes are separated into different gametes. During fertilization, these gametes combine, rejoining the alleles from each parent to form a new genotype in the offspring. This segregation and rejoining of alleles is fundamental to the inheritance of traits.
What is mendels theory of the transfer of traits?
Mendel's theory of the transfer of traits, also known as Mendelian inheritance, states that genetic traits are determined by the inheritance of alleles from parents. These alleles segregate independently during gamete formation and randomly combine during fertilization, resulting in offspring with specific traits based on the combinations of alleles inherited.
What is it called when gametes are produced and each gamete receives one of two possible alleles?
The process is called meiosis, specifically during the formation of gametes, where alleles segregate. Each gamete receives one of the two possible alleles for a given gene due to the law of segregation, which states that allele pairs separate during gamete formation. This ensures genetic variation in offspring when gametes combine during fertilization.
Does alleles fuse during self-pollination?
No, alleles do not fuse during self-pollination. Self-pollination involves the transfer of pollen from the anther to the stigma of the same flower or between flowers of the same plant. The fusion of alleles occurs during sexual reproduction when gametes from two different individuals combine to form a zygote with a unique combination of alleles.
Is one result of gamete formation through meiosis and fertilization during sexual reproduction that promotes biodiversity within a species?
Yes, gamete formation through meiosis and fertilization during sexual reproduction promotes biodiversity within a species. Meiosis introduces genetic variation through processes like crossing over and independent assortment, resulting in unique combinations of alleles in gametes. When these gametes fuse during fertilization, they create genetically diverse offspring, which enhances the adaptability and resilience of the population in changing environments. This genetic diversity is crucial for the long-term survival and evolution of species.

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.
What Percentage Of The Offspring Will Be Expected To Have The TTYy Allele Combination?
50% of the offspring are expected to have the TTYy allele combination. This is because the TY and Ty alleles segregate independently during meiosis, resulting in a 1:1 ratio of TY:Ty alleles in the gametes that combine during fertilization.

Why are desivable traits not always passed to offspring?
Fertilization involves a random selection of alleles which are combined.
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.
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
Does alleles fuse during self-pollination?
No, alleles do not fuse during self-pollination. Self-pollination involves the transfer of pollen from the anther to the stigma of the same flower or between flowers of the same plant. The fusion of alleles occurs during sexual reproduction when gametes from two different individuals combine to form a zygote with a unique combination of alleles.
The theory of segregation applies more specifically to events occurring in preparation of?
The theory of segregation primarily applies to events occurring in preparation for meiosis, particularly during the formation of gametes. It describes how alleles for a gene separate from each other so that each gamete carries only one allele for each gene. This principle is a fundamental aspect of Mendelian genetics, ensuring genetic diversity through the combination of different alleles during fertilization.
When do alleles separate for the same trait?
During meiosis.
