Alleles are different forms of a gene that can produce varying traits or characteristics, such as eye color or hair texture. When we inherit alleles from our parents, the combination we receive influences how we look. For example, if one parent passed on a dominant allele for brown eyes and the other a recessive allele for blue eyes, the dominant brown allele would likely determine our eye color. Thus, alleles play a key role in determining our physical appearance.
In a heterozygous individual, the alleles for a trait are different. Each allele may be represented by a different letter (e.g., Aa), where one allele is dominant and the other is recessive. The dominant allele is typically expressed in the phenotype, while the recessive allele is not unless the individual is homozygous recessive.

You have 2 alleles for each trait you may have. One is on the chromosome from you mother, the other is on the other chromosome from your father. You have 2 of each of our 23 chromosomes (one from mom, one from dad). This is why you look a little or a lot like your parents.
Scientists can tell if evolution is occurring by observing changes in the genetic composition of a population over time, such as the frequency of certain traits or alleles. They also look for evidence of natural selection, genetic drift, or gene flow influencing the population. Comparing populations over different generations can help determine if evolutionary changes are taking place.
Even identical twins are heterozygous for many alleles. Recombination would produce gametes with many different combinations of those alleles in each individual. Their offspring, as a result, could have very different genotypes than either parent, and thus look different as well.
It will get taller but you also can tell by how small it was before and how big it is now.
Sister chromatids dont over cuz they dont look it up lmfao
It can provide different looks because each allele gives a different look
nothing can determine what the offspring will look like except for the dominant alleles for eye color
look it up on some other website please because i dk I love dgf
Brothers and sisters are not identical because they have different combinations of alleles.

It's spelt homozygous, which may explain the difficulty when you tried to look it up haha. I don't know your level of knowledge, but it refers to genetics. There are two alleles (allele = different type of a gene) at each locus (locus = physical location of a gene on a chromosome) on a chromosome. If these alleles are the same, they are considered homozygous. I'll give an example: we have a snake that either has spots or it doesn't, and spots is the dominant phenotype (phenotype = physically expressed trait). If it has spots, then it has the S allele, and if it doesn't have spots, it has the s allele (spots is uppercase and no spots is lowercase). If the organism does not have spots, then it is homozygous recessive with two s alleles (ss). If it had spots but had one S allele and one s allele (Ss) then it is heterozygous (two different alleles). If it had spots and had two S alleles (SS) then it is homozygous dominant. I hope that clarified.
Unfortunatly, that is a very specific topic to find in any magazine. But, if you look on different bathroom design websites, you will find an article to help you.
rain all depends on the water cycle. It takes a long time to explain but look at thisif that doesn't help and you want specifics then look at this This is the best i have
