anatomical homologies
What else can I help you with?
What is the definition of homologous?
Homologous means similar to but not the same thing, as a squirrel's foreleg is homologous to a human's arm.
What is the definition of hindlimb?
hind limb: a posterior appendage such as a leg or the homologous structure in other animals.
How do you write the definition of homologous chromosome using the terms gene and allele?
Homologous chromosomes are pairs of chromosomes in a diploid organism that share the same genes at the same loci. Each gene may have different forms, called alleles, on the homologous chromosomes.
What is the definition of homologous chromosomes in biology and how do they contribute to genetic variation?
Homologous chromosomes are pairs of chromosomes that have the same genes in the same order. During meiosis, homologous chromosomes exchange genetic material through a process called crossing over, which leads to genetic variation in offspring.
Body parts similar in origin and structure are what?
homologous
How would you use homologous structure in a sentence?
I learned about homologous and heterozygous structures in Biology.
How many possible homologous chromosome alignments are there?
There are 2n possible homologous chromosome alignments, where n is the number of homologous pairs of chromosomes.
Are sex chromosomes homologous in humans?
Yes, sex chromosomes are homologous in humans.
What are the matching pairs of chromosomes in the diploid cell called?
They are called homologous chromosomes (but can also be referred to as homologues or homologs).
Are homologous chromosomes present in both mitosis and meiosis?
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
What is a sentence using the word homologous?
The homologous is the study of animals.
What is a process in which homologous chromosomes exchange portions of their chromatids during meiosis?
The process is called crossing over or genetic recombination. It results in genetic diversity by shuffling genetic information between homologous chromosomes, leading to unique combinations of genes in the offspring.
