How do traits get inherited?
Through genetics, you have two alleles(different versions for a gene) for each gene, one from each parent
How does probability apply to heredity?
Probability applies to heredity with the inheritance of certain genes and alleles that together make up heredity. The question has to do with probability in that each parent cell can contribute one half of its genes. Because it splits through meiosis a parent cell can have one of two parts. The other parent cell has the same possibility of splits. Therefore, one half times one half is one fourth. That is the probability of each gene being passed on.
Suppose that each year one half of the population have two offspring per person and the other half have none If all members die after one year what is the resulting growth rate?
i think it will stay the same each year
What does the rate in which the second quantity in the comparison is one unit mean?
It is called the unit rate and gives the number of the first unit for each one in the second.
What is the lenght of one side of a cube with a surface area of 1350?
Each side measures 15. Divide the known surface area by 6... this gives you the area of one side. The square root of the area of one side will give you the length of each side.
Each parent gives one set of what to the offspring?
chromosomes.
Each parent gives one set of these the offspring?
genes
What percent of each alleles does each parent contribute to their offspring?
50% from each parent: one allele in each gene, each parent, for a total of two.
How many genes does an offspring receive from each parent for a trait?
23 from each parent... that's a total of 46 genes from both parents :D
How many chromosomes does each offspring have?
4 because the parent cell has four chromosomes arranged in 2 pairs. Each offspring has 4 chromosomes, one pair from each parent.
Describe one way which the plantain can reproduce?
Some protists also can reproduce in pairs. Each member of the pair gives some hereditary material to the offspring. The ofspring are different from either parent. Hereditary refers to properties that are passed from parent to offspring.
How many variants of a gene can an offspring have?
One from each parent
Are all genes passed on from each parent to each child?
Only half of each parent's alleles are passed to their children. This means that parent 1 who is Aa at one gene locus will only pass A or a on to each offspring. Parent 2 may be AA, aa or Aa and will also only pass one allele on to each offspring.
What is meiosis in human?
In sexual reproduction, two parents give rise to an offspring with an unique gene combination from either of them-each parent gives 1/2 of his/ her genes to the offspring. A Gene is a discrete unit of DNA that codes one protein, perhaps one of the many enzymes needed by our bodies.SOMATIC CELL have two sets of chromosomes; one set from each parent.
When fertilization occurs offspring inherit?
One homologous chromosomes in a pair from each parent
To produce the offspring each parent had to have at least one of what type of allele?
homozygous recessive
What is the principle that each parent passes only one allele for a trait its offspring?
Segregation
