Are humans diploid organisms? Based on human reproduction and the assigned lesson, why or why not?
a. Are sexually reproducing organisms usually diploid?
b. What is a gene allele? Gene "bingo" is present once in a complete haploid set, how many alleles does a diploid individual have? How many copies of gene "bingo" are present in a diploid individual?
Question 1: Yes humans are diploid species. They consist of 23 pairs of homologous chromosomes.
a. Are sexually reproducing organisms usually diploid?
yes sexully reproducing organisms are diploiid from single cell organisms to multicellular organisms. but the number of vegetative homologous chromosomes and sex chromosomes are different. Upron fertilization from haploid gametes of male and female roduces dipliod zygote leads to Adult.
b: Answer
Gene allele:
A gene is a widen form of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms;
An allele is found at a fixed spot on a chromosome. Chromosomes occur in pairs so organisms have two alleles for each gene.
When the haploid sperm and the haploid egg combine (at the moment called fertilization) they create a diploid offspring cell. Bingo.
Each Bingo has chromosome of its own individual number and each chromosome consists of smaller segments of DNA known as genes (a number copies representing each trait)).. These genes contain specific bits of genetic information that come in different flavors, called alleles.
