How many different gametes can RRYy parent form?
Four can be formed RY, Ry, rY and ry.
How many different allele combinations would be found in the gametes produced by a pea plant whose genotypes are RrYY?
It depends on the allele combinations of the other pea plant parent. If the other pea plant parent also has a genotype of RrYy, then there are 16 combinations. If the other parent has genotype RRYY, then there are only 4 allele combinations. If the other parent has a genotype of RrYY, then there are 8 allele combinations in the gametes. If the other parent has a genotype of RRYy, then there are also 8 possible combinations in the gametes. Finally, if the other parent has the genotype rryy, then there are 4 gamete combinations.
What two cells come from parent cells?
Two parent cells that join together to form a new individual is what is referred to as reproduction. This is achieved by fusion of the male and female gametes.
Are offspring of gametes haploid or diploid?
Gametes are haploid. When two gametes unite during fertilization, they form a diploid zygote, genetically unique from either parent, and the first cell of the offspring. The zygote is not really considered an offspring of the gametes, but of the parent organisms that produced the gametes. For example, a human zygote is the first cell of a human baby formed when a sperm from a male and an ovum from a female unite during fertilization. The zygote and subsequent baby are the offspring of the mother and father.
From which cell does human life begin?
A human is created by two gametes, one from each parent, fuse to form a zygote, which is unique from the cells of either parent and is the initial cell that eventually becomes the offspring.
Are the gametes produced in insect haploid or diploid?
Gametes produced in insects are haploid. This means they have half the number of chromosomes as diploid cells in the insect's body. When two haploid gametes (one from each parent) fuse during fertilization, they form a complete diploid zygote.
How are similarities passed from parent to offspring?
Through the parental genes forming the two gametes.
Where do zygotes get chromosomes from?
A zygote is produced by the merger of two gametes, which are an ovum and a sperm. The gametes are produced by the two parent organisms. That's where the chromosomes come from. This process is known as heredity.
Which one involves gametes sexual reproduction or a sexual reproduction?
Sexual reproduction involves the fusion of gametes from two parent organisms to produce offspring with genetic variation. Asexual reproduction does not involve the fusion of gametes; instead, offspring are produced from a single parent organism and are genetically identical to the parent.
What are the possible gametes types that can be produced from a parent who is YrRr?
Make two punnett squares- one for Yy x YY and one for rr x RR the possible outcomes for Yy x YY are: YY Yy the only outcome for rr x RR is Rr. so the gametes of the two could be either YY Rr or Yy Rr
What is gamete fusion?
It is the process during the formation of a zygote when two gametes, each carrying a different set of chromosomes, fuse together. This ensures that the developing zygote has a set of chromosomes from each parent and the cells can divide properly.The fusion of gametes is called sexual reproduction. There must be two gametes present for sexual reproduction to occur and they must have to correct number of chromosomes.
Do two sex cells combine during meiosis?
No, two sex cells do not combine during meiosis. Meiosis is a type of cell division that involves two rounds of division, resulting in the production of four haploid cells (gametes) each containing half the number of chromosomes as the parent cell. Two gametes - one from each parent - combine during fertilization to form a diploid zygote with the full set of chromosomes.
