The arrangement of homeotic genes along chromosomes of vertebrate and invertebrate animals corresponds to the expression pattern of the genes along the anterior-posterior axis of the developing embryo.
<h3>What are homeotic genes?</h3>
- Homeotic genes are a group of body pattern forming genes which control the development along the anterior- posterior axis of the developing embryo.
- These encode transcription factors which control and specify the genes involved in body patterning. These provide identity to the segments during embryo formation.
- Genes located in the 5’ end act on posterior side whereas the genes on 3’ end act on anterior region.
- Homeotic genes are evolutionary conserved and control body specification, patterning and differentiation.
- The loss of function of any of the gene changes the body pattern and affects the development.

The sporophyte are produced before the gametophyte. Is is through the spores that sex cells are made up. The sporophyte contain the genetic material that will used to make the gametes. Therefore, the gametophyte will have half of the genetic material of the sporophyte.
Answer:
a- brown eyes
b- blue eyes
c- brown hair
d- widows peak
e-short arms
f- can roll tongue, long arms
g- brown eyes, brown hair
h- widows peak, short arms
i- brown eyes, can roll tongue
j- brown eyes, brown hair, no widows peak, long arms, can't roll tongue
Explanation:
So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...
RR would show the dominant trait of white fur
Rr would show the dominant trait of white fur
rr would show the recessive trait of brown fur
